  1. Geo

    Hey! Was wondering, the 1000mg stuff, would I be able to make 10 x 100 mg 10ml bottles of juice. Would be like 1ml of base per bottle to get the 100mg each? Sorry for the daft question! Thanks in advance 👍 oh, and the terps you use, are they extracted from weed, or plant derived to build the profile?

    • Clara

      Hello Geo, Thank you for your interesting questions 🙂

      We decided to release Harmony Pure CBD base for that exact purpose, so you can add CBD to any of your favourite e-liquids. The certified CBD concentration in a 10ml bottle will allow you making 10 x 100 mg 10ml bottles of CBD e-liquids

      We are using a complete combination the terpenes β-Caryophyllene, Myrcene and Limonene to recreate the profile of the strains OG Kush, Super Lemon Haze and Mango Kush flavour. You can see the amazing reactions of people trying our CBD e-liquids here: The Harmony Effect

      Have a great day Geo!

  2. linda gomez

    Can I vape this as it is without diluting it in any way?

    • Clara

      Hello Linda, Thank you for your message 🙂 The Harmony CBD Pure Base is made to add a CBD boost to your favourite e-liquid. It is made to mix with another e-liquids and can’t be vaped alone. Have a great day!

  3. Katie

    LOVE this stuff, I put it in most of my eliquids and makes me wanna try your cannabis flavoured products too 😀

    • Clara

      LOVE you Katie!! Feel free to send us a message at [email protected], we will be happy to send you a promo code to try our cannabis flavours 😀

  4. Lorenzo

    10 ml – 100 mg CBD base
    How much of the base would be enough for a normal 10ml e-liquid, in order to get the effect?
    I’m really confused as to how much of the base I should add to my normal (no nicotine) e-juice..
    Hope you can help me! 🙂

    • Clara

      Hello Lorenzo!Thank you for your comment 🙂 The correct dose of CBD varies significantly from individual to individual. When trying to determine the correct amount of CBD Pure Base you need to start small. a few CBD pure base drops in your normal 10ml e-liquid is a good way to begin, if you feel it is not enough then you will be able to go up gradually! If you have any more question, please come back to us! Have a great day

  5. Ricky

    Hi, Just ordered some ‘HARMONY CBD PURE BASE’ from a local vendor! And am stuck on the last part! What ratio of VG / PG of E-liquid would be best if I added the whole 10 ml (1000mg CBD) to a 30ml of E-liquid. I presume 100% VG E-liquid for a final 75/25 ratio? But maybe that’s just to much :D. Thanks guys!

    • Clara

      Hello Ricky! Thank you for your purchase! The ratio obtained by adding 10 ml PG to 30 ml VG is far from our usual recommendation of 80/20 PG/VG. We wouldn’t recommend such a high VG ratio since the solution would not be stable and therefore you will need to add PG to it. Feel free to let us know how it went with HARMONY CBD PURE BASE, we would be happy to have your feedback! If you have any more question, please come back to us!

  6. Antonio

    Prodotto incredibile, il rapporto qualità-prezzo è altissimo. Lo metto in tutti i miei e-liquids e finora non sono riuscito a trovare di meglio sul mercato, si sposa alla perfezione con tutto. Per liquidi al CBD consiglio un ratio PG/VG 80-20, in modo da mantenere il liquido stabile e non rovinare la sigaretta.
    Un saluto e grazie!

    • Clara

      Grazie mólto Antonio <3

  7. xorxe kakout

    hello! im e-smoker i smoke base 50/50 with 4% nikotine inside my question is better put in my 150ml the three bottles of pure base or the three bottles of classic hemp because of terpenes i want terpenes and i think the pure base dont have..and its ok for the dose 150ml of my base 3 bottle of cbd?.thanks

    • Clara

      Hello Jorje! Thank you for your interest! We wouldn’t advise you to mix Harmony CBD Hemp e-liquids with another juice since you will lose the unique aroma of it. In order to enjoy Harmony e-liquids to their best, it is better to vape them alone. On the other hand, Harmony Pure CBD Base is made to mix with your favourite e-liquids for an added CBD boost. It only contains PG and CBD so you can create your personal ratio fitting your vaping preferences. Three bottles of CBD Pure Base is okay for a 150ml juice bottle. You will be able to adapt the dosage according to what you want 🙂
      If you have any more question, don’t hesitate to ask! Have a great day!

  8. Joe

    God I’m so happy this came out. As soon as I finish my last drop of original Hemp Harmony one I’ll buy me one of these. Not that the taste was bad, but you can’t really mix it with other flavors (well, maybe you can, but it’s too much of a hassle for me to find the right combination). GREAT customer care as well with good vibes all around. Love. Joe

    • Clara

      Hello Joe! Amazing to hear! Good vibes possible thanks to users like you <3 Thank you!

  9. Ernesti

    Hello, I just purchased your 1000mg pure base CBD from House of Vapes London. How much CBD is there in one drop?

    • Clara

      Hello Ernesti! Thank you for your purchase! It is an interesting question challenging to give an accurate answer since it will depend on various parameters as the drop size. Knowing that each Harmony Pure Base CBD 10ml bottle contains 1000mg of CBD, we know that 1ml will contain 100mg of CBD. From there you can easily scale the CBD to meet your needs 🙂

  10. Lorenzo

    Hi, I really would like to try for the first time the CBD pure Base (300mg) but it’s the first time for me because till now I just used the “original hemp e-liquid”. Can you advice me how I can use it? Anyway I want a final e-liquid with an high concentration of cbd (around 300 mg/ml). Thanks a lot

    • Clara

      Hello Lorenzo! Hope you are doing great! Harmony CBD Pure Base is really easy to use, you just have to add a few drops to your favourite e-liquid, shake and you are ready! The highest CBD concentration for that products is 1000mg of CBD or 100mg per ml.You can easily scale by mg to mg to meet your needs 🙂 Don’t hesitate to come back to me for any question! Have a great day

  11. Ahmed

    can someone explain so you add this to your favourite e liquid then what does it get you high or something like that can someone please explain

    • Clara

      Hello Ahmed! Thank you for your question 🙂 Indeed, Harmony Pure CBD Base is made to be added directly to your favourite e-liquid! CBD being non-psychotropic, you won’t feel any high from it! Don’t hesitate to ask if you have any further question! Have a great day!

  12. Jasper

    Hey! I have a question. How much bottles of this CBD booster do I need to add to my shake and vape bottle(50ml) to have a good effect? 🙂

    • Clara

      Hello Jasper! Thank you for your message 🙂 It is hard to answer precisely to that question as it will depend on the CBD concentration of Harmony CBD Pure Base chosen. As a general guide, please find the CBD percentage of CBD concentration by adding Harmony Pure CBD Base into the 50ml base:
      – Pure CBD Base 100MG into 50ml base = 2mg/ml = 0.2% CBD
      – Pure CBD Base 300MG into 50ml base = 6mg/ml = 0.6% CBD
      – Pure CBD Base 600MG into 50ml base = 12mg/ml = 1.2% CBD
      – Pure CBD Base 1000MG into 50ml base = 20mg/ml = 2% CBD
      Let me know if you have any other question 🙂 Have a great day!

  13. Cesar

    Hello Clara.. I have one question .. is ok mix the Crystal CBD with the OG-Kush or with the CBD Pure Base zu Vapen ?? when is yes …How much crytals in 10 ml ?

    • Clara

      Hello Cesar! Good to hear from you again 😀 Indeed you can mix Harmony Pure CBD Crystals into your favourite e-liquids or into Harmony Pure CBD Base ( don’t forget that the Harmony Pure CBD e-liquids can’t be vaped alone). Concerning the Pure CBD Crystals dosage, the best is to begin low, for example, 10-20MG, if you feel it is not enough then you will be able to go up gradually 🙂 Feel free to share your experience 😀

  14. Jo

    Thanks Harmony! I’ve been looking for something like this! I have a collection of different flavour e-liquids and wanted to add some CBD and this one is great. Lasts ages, literally just add a few drops to my e-liquids and i’ve got a nice CBD boost! Harmony’s customer service was really nice too, explaining exactly how to use the products. Will recommend it to friends 🙂

    • Clara

      Hello Jo! A Nice customer support is made possible by nicest users! Your great words are greatly appreciated <3

  15. jakob

    What’s the purity of your CBD?

    • Clara

      Hello Jakob! Thank you for your message 🙂 Harmony Pure CBD Crystals are 99.9% pure. You can find all our certificate of analysis by clicking here. Have a great day!

  16. Chanise

    Hi, would like to know how many drops per bottle in the CBD Pure Base eliquid so that I calculate how much mg I am using daily when I add this to my usual eliquid. Thanks

    • Alana

      Hey Chanise! That’s a challenging one to give an accurate answer as it will depend greatly on the size of the drop. Knowing that for the Harmony Pure Base CBD 10ml bottle containing 100mg of CBD, 1ml will contain 10mg of CBD. It is hard to say exactly how many drops are in 1ml but we estimate it is between 20-40 drops depending on the size. With that being said if you are in the 30 drop range each drop will contain ~,33mg of CBD. Hope that helps!

  17. sandieastleysmith

    Such a great product. I love how I can add to all of my e-juice. Fast delivery in the post. Thank you harmony I am impressed.

  18. nevertango

    Absolutly amazing producrs, i have bought quite a few different kinds for my wife to take away some of her pain from her illness. The effect have been so impressive that you guys need the praise and you just got yourself some new customers for life and the recomendations for you was given on pretty much at day one!

    • Magda

      Thanks so much! We really appreciate the kind words and are happy you’re part of the Harmony family for life! <3

  19. mohamed.diop

    can i use it with my e-cigarette Istick Pico 25 with liquid with 30% PG and 70 % VG and 3mg nicotin?
    I read that the CBD blendeds with nicotins loses its effects.

    • Magda

      Hey, yes that vaporiser will be suitable for vaping Harmony e-liquids. Harmony CBD is similar in consistency to most e-liquids, so feel free to vape it at your preferred wattage. In general, we advise keeping the setting between 10-30 watts depending on the coil you are using. This will provide a great flavour while not vaporizing too much e-liquid. Vaping at higher than 40 watts can alter the flavour by disrupting the delicate terpene profiles.

      Harmony CBD e-liquids do not contain nicotine as we believe CBD is a much better alternative as it is a non-toxic and non-addictive compound. However, it is possible to mix Harmony Pure Base with a nicotine e-liquid if you wish. Hope that clears things up for you 🙂

  20. Charlotte

    I’m very confused! Could you advise me on the right e-liquid to mix with pure base please? I’m unsure about the PG/VG levels.
    I am a complete newbie to vaping and CBD!

    • Magda

      Hi Charlotte, thanks for reaching out! The Harmony Pure Base is a flavourless e-liquid made up of just PG and CBD. Therefore it cannot be vaped alone but is intended to be mixed with a VG based flavoured e-liquid.

      If you prefer, you can also try one of the flavoured Harmony CBD e-liquids which already contain both PG and VG (plus CBD and terpenes!) so they don’t need mixing, simply add them to your vaporiser tank and go 🙂

      Let me know if you have any more questions!

  21. mark

    hi there have a bottle of 300mg purebase how much would i put in a 10ml bottle of vape juice to mix thaks

    • Athena CS

      Hi Mark – we’ll need some more information to answer your question. Can you email us at [email protected] so we can help? Talk soon!

  22. Chizn

    Thc, how many percent thc is in here?

    • Athena CS

      Thanks for your question. There is no THC in any of our e-liquids, including the Pure Base

  23. Richard

    Why does the english ingredients description say “Propylene Glycol” (PG) but the German “Vegetable Glycerine”, so VG ???
    How can such a mistake happen?

    • Alana

      Hey Richard, good catch! It looks to be a typo on our German version, not to worry though it is the same great PG formulation inside 😀

  24. Ed

    I try to avoid e-liquids with high PG as they always give me a sore throat. I can see you recommend an 80/20 ratio (PG/VG) however this would be too much PG for me. Is there a minimum/maximum ratio of PG/VG you could suggest for me? Thanks

    • Athena CS

      Hi Ed! Thanks for your comment. Good point: everyone’s different and the ratio affects everyone differently. We use the 80/20 ratio to ensure good solubility of the high-quality CBD in our formulations. Our product team conducted hundreds of tests to come up with this “magic number.” Our advice would be to try different combinations until you find one that feels right for you. Let us know how it turns out!

  25. arnold

    Why I can’t vaped The Harmony Pure Base 1000mg alone?

    • Alana

      Hey Arnold, our Pure Base shouldn’t be vaped alone as the base is pure PG. The PG gives the throat hit meaning it can be harsh when vaped on its own!

  26. Massimiliano Raffaele Mileti

    I did leave a nice review yesterday as I received my first bottle of CBD pure base. I expect it was too much so I will just keep it short and sweet. Amazing product thank you.

    • Alana

      Hey Mass! Glad to hear you’re enjoying it and it was exactly what you were looking for 🙂

  27. Jade

    The 1000mg pure base recrystallises no matter what brand of e liquid I add it to. I always add 0.5ml to a 2ml . tank of 50/50 VG/PG e-liquid. I even tried 60/40 PG/VG…Am I doing something wrong?

    • Alana

      Hey Jade, with the 1000mg Base you will tend to have more crystallization due to such a high CBD content. Typically the higher the PG content the less likely you will be to have this problem. Hope that helps!

  28. John

    Hi there, I am interested in the 300mg strength, as I make up bottles of e-liquid of 100-120ml, how many drops would I need to put in. I use a mix of 80/20 & 6mg nicotine.

    • Susie

      Hey John! Thank you for reaching out 🙂 If you want to have the same concentration as our 300mg pure base, you would need 3000mg of CBD for 100ml making the concentration 3%. If your simply looking to add the 300mg base to your 100ml for added CBD, it really depends on how much you want to have. Keep in mind 1ml of pure base will have 30mg of CBD. Hope this helps, if not send us an email with any further questions!

  29. David

    can i mix this with THC e-juice?

    • Susie

      Hey David, thanks for your comment! Sure you can 🙂

  30. abschweitzer

    I’ve tried various CBD products and this pure base is one of the best around. 10/10 will buy again. 🙂

    • Alana

      Hello!!! So glad you’re loving it! Send us an email before you buy next time, we would love to send you something <3

  31. Ant

    lab reports?

    • Susie

      Hey Ant! thanks for reaching out. I’m happy to share with you our certificate of analysis. We’ve sent you an email!

  32. George

    Hello, I’m a common vaper of e-liquids with or without nicotine, now I’m looking for a CBD e-liquid that helps me to relief the pain in my knees, I’ve already tried many of your flavors with 100 mg of CBD without any luck (null effect). AFAIK this pure CBD is the one with the highest CBD concentrate and should help me, but reading previous comments you said It’s required to mix it with another e-liquid, could you please give me an explanation for dummies about how much ml of pure CBD liquid should I mix with my normal free-nicotine liquid to obtain highest CBD ratio and non burning my coils? (My vaporizer is the SMOK Mag)

    • Susie

      Hey George, it all depends on how much CBD you would like to be adding to your current liquid. To give you an idea 1ml equals around 20-30 drops (depending on the size of the drop). With the 300mg, 600mg or 1000mg Pure Base as they are high in concentration you can start with a few drops and then go up to 50% of your tank. Furthermore, our products contain CBD and it is important to understand that they are not medicine. Feel free to email us for further details 🙂

  33. atrsplace

    great product, i love the mint flavour also. highly recommend harmony to all my friends that use cbd

    • Susie

      Hey! Thanks for your comment 🙂 Glad you love it!

  34. Issy

    I am a complete novice as never caped CBD before.. I currently cape a menthol nicotine 6mg e-liquid. Which if your liquids would give me a minty/menthol flavour?.

    • Susie

      Hi! thanks for reaching out feel free to search in our shop page on the website we to have a Moroccan mint flavour e-liquid!

  35. Kelvin Campelo

    I have using OG Kush(100mg), but now I’m thinking to buy a 1000mg pure base to make my own e-liquid. Can I just merge with Chemnovatic 70/30 VG/PG Base? I want to get a 100mg/10ml e-liquid.

    • Alana

      Hey Kelvin! Yes you can add it into that, I would recommend with starting with less Pure Base and scaling up though as with higher VG amounts the CBD could recrystallize.

  36. Ronny.b.moen

    Hey. how does this work exactly? on the 10mg/ml base.
    1ml base and 9ml juice will give 10ml with 10mg/ml ?

    • Susie

      Hey, thanks for your comment! It all depends on how much CBD you would like to be adding to your current liquid. To give you an idea 1ml equals around 20-30 drops (depending on the size of the drop). With the 100mg Pure Base that means each 1ml contains around 10mg of CBD. We recommend to start out by adding a few drops into your liquid and scaling up from there up to not more of one third of Pure base in your tank. Let me know if you need more info! 🙂

  37. Reiss

    Hi. I’m looking to buy some pure base and want to know if you would recommend buying the 300mg or the 1000mg and using sparingly as, I read that the 1000mg could crystalise? Does that mean it could crystalise in the pot it comes in after a while or after being mixed with normal e-liquid, and if it does, can it still be used?

    Also, I’ve heard th OG Kush is good and would like some recommendations on some other flavoured options that are smooth on the throat and have a good flavour and effect?

    Lastly, I get the impression from other reviews that various products have varying effects. Can you advise on what product(s) may be best for each of the following;
    1) Insomnia
    2) Anxiety
    3) Body relaxation




    • Alana

      Hey Reiss, Our pure base can crystalize when you mix it which is usually due to the base ratio you are mixing it with. For the 100mg it is best to have a higher amount of PG than VG in order to keep that from happening! If you are interested in the OG Kush I would recommend trying out the Exodus Cheese or the NYC diesel which are the less sweet and more woody of the flavours 🙂 Keep in mind our products contain CBD and it is important to understand that they are not medicine. They don’t treat, diagnose or cure any disease, physical ailment or condition. With our CBD products, you can enjoy a great taste and, at the same time, be sure about what you are consuming thanks to our high-quality control standards.
