    Hydroton, Baking to Sterilize?

    @xtsho, I have done the soak in hydrogen peroxide myself, with a rinse after a few days. Because of epilepsy I am sometimes stuck in bed for a little while, while I recoup from a seizure (or several that cluster) and the last thing I need is a vat of h202 evaporating in my garage and then...

    Hydroton, Baking to Sterilize?

    @Coalcat, I would be careful doing this... The outer coating on the hydroton is a metal oxide.

    Hydroton, Baking to Sterilize?

    @coreywebster, Thanks for the PDF, it shows that I was right about the outer portion being Iron (III) Oxide. This stuff should come with a warning to not use it with hydrogen peroxide above 3% and certainly to not allow hydrogen peroxide to evaporate on it. Actually if you were to grind this...

    Hydroton, Baking to Sterilize?

    Here's a video showing hydrogen peroxide squirted into a bucket of red iron(III) oxide.

    Hydroton is made out of Poop (or flyash or about 100 other things)!!!

    For anyone who reads Chinese, here's the PDF of the patent. Here is the google patents website that has a partial translation https://patents.google.com/patent/CN101148346A/en

    Hydroton is made out of Poop (or flyash or about 100 other things)!!!

    Hello All, So check this out... What we think is hydroton is actually ceramsite and it comes from China. When we think of hydroton what we are actually thinking of is "Haydite" which was invented in 1917. Then some time ago they stopped making haydite and the hydroton soucres ran dry...

    Hydroton, Baking to Sterilize?

    Hello All, Has anyone ever baked their hydroton to sterilize it? I am considering some different ways to clean up my hydroton before the next grow and I am just curious if anyone has ever baked theirs. IF so what temperature and how long? Does it stink when it bakes? I am currently using...

    Minimum Alcohol % Needed to Dissolve Cannabinoids

    @cannabineer, Toulene is only “not as toxic” by theory, because there hasn’t been sufficient testing. For all we know it could be worse than benzene. Plus “not as toxic” in chemistry is like saying sulfuric acid isn’t as strong as aqua regia… They will both eat right through you… Just one will...

    Minimum Alcohol % Needed to Dissolve Cannabinoids

    @Thundercat, I would love to be able to use basic tinctures, but I am super sensitive to THC, so I have to know exactly how much I am working with so I can then dilute it down so the THC doesn’t trigger an anxiety attack. To be honest the process of distilling is no more complicated than iso...

    Minimum Alcohol % Needed to Dissolve Cannabinoids

    @OPfarmer, The Source Turbo looks pretty cool, it’s sort of a high tech “Super Flower Tower.” This is very similar to the process of using an airstill, except the return on yield is 95% instead of 70-80% like with the air still. The final product is going to be 20:1 CBD:THC, which I will...

    Minimum Alcohol % Needed to Dissolve Cannabinoids

    @Fadeddawg, I was planning on using a fractionating distiller with vacuum and if need, also molecular sieve 3A to extract the water but leave the ethanol. I do have concerns about using a “pot” still so while the modified BHO generator is cool, this would be a problem legally. Lab-ware on the...

    Minimum Alcohol % Needed to Dissolve Cannabinoids

    @cannabineer, I know, but benzene is the most commonly used entrainer and I didn’t want to go listing all the non-polar solvents that could be used. I figured if the alcohol needed to be higher than 95:5, I could always use a molecular sieve and then reclaim the sieve for regeneration and...

    Minimum Alcohol % Needed to Dissolve Cannabinoids

    OPfarmer, I am just curious. I am thinking of making my own alcohol for extraction. I use iso but I would prefer something that isn't a straight up poison. I cannot buy everclear where I live and to have it delivered is crazy expensive. I can buy all the equipment to make it myself for what a...

    Minimum Alcohol % Needed to Dissolve Cannabinoids

    Hello all, Does anyone know the minimum alcohol content required to dissolve cannabinoids? We all assume it’s 99%, right? But people people use everclear all the time, which is an azeotrope of alcohol and water, 95:5. This is strongest you can get alcohol by simple steam distillation. To go...

    Growth rate?

    @Way2-High, You callin me old? LOL

    Can anyone guess yield?

    We need a few more details... What has been your nutrient schedule (preferably in EC)? Watering schedule? Any setbacks (bugs, root rot, etc...) You said it's your first grow, but the way those plants are tended, either you have been doing your homework or you have someone who knows what they...

    Growth rate?

    Were you doing it back in the VHO days? I had an IceCap solid state VHO ballast and that was cutting edge tech back in the day, coupled with Actinic tubes, there wasn't anything I couldn't grow! I suspect these days everyone is using LEDs and T5's. Just about the time I got out of the hobby was...

    I like Big Clive's videos, he likes to take things apart, show you how it's made and then explain how if you use it, it's going to burn your house down!!! LOL...
