So Im sure everyone knows how to brew alcohol… suger+water+yeast gets alcohol…right.
So in depth; 1 mol (chemistry term) of sugar produces 2 mol of co2 gas. So… in a typical brew yielding 1 gallon of pure ethyl alcohol about 30 mol’s of co2 are produced (you do the math). 30 mols of co2 is about 720 liters of co2…alot. So for about $8 (the cost of the sugar), you get a gallon of alcohol and 720 liters of co2. This process takes about 3 days.
In come the hempy buckets
So you hook up your co2 regulator to your slightly pressurized co2 off gas from your brew, with the timer, and then circulate the co2 from the bottom of the hempy bucket (very bottom center), up through the media and then out into the grow where the co2 is monitored. Co2 to the root zone can be even more beneficial than co2 in the actual tent.
One downside, micros that require oxygen will not live in this.
And presto! For about $2.50 a day you are growing bomb weed.
Yeah, you could even incorporate a reservoir on the bottom of the hempy bucket . Bubble the co2 though the rez up though the mix. Double bucket hempy bucket!!
People have been growing with soilless media and hydroponic nutrients for decades.
However, the hempy bucket as we know it was popularized by a user on icmag called “dalaihempy”. Hundreds of pages of threads on it.
There is no benefit to supplementing CO2 in the root zone. You might tank your bucket pH from the carbonic acid, however. No need to reinvent the wheel, it’s been done every which way.
In 1910 : Man trip and fall into a tub of perlite and hummus and synthetic nuts - unable to get out he grew his plants right there in the same nasty tub. To his surprise m, he grew some dank! Mans name was Hempy!
He was finally able to get out of his own bucket post-season with the help of his runaway dog and quickly began to share his secret ideas with the Illuminati. I just made this up don’t believe a word of it
On a spliff note: I don’t think running c02 this way into a grow is beneficial. I think to understand why we must look at photosynthesis… I could be wrong though ! I’ve seen some weird shit lately
No señor just asking a few people - that link was good but I need to know how they apply and other contrasting experiments
“While elevated RZ CO2 did not alter biomass accumulation and nutrient concentrations in pepper grown aeroponically, it decreased foliar Mg and S concentrations in lettuce grown aeroponically even though nutrient contents (concentration x biomass) did not differ between treatments, due to 22% more biomass than control plants. In addition, elevated RZ CO2 enhanced N, P, Cu and Zn contents relative to control plants, indicating greater uptake of those elements. Nevertheless, there was no consistent relationship between plant growth promotion and altered plant nutrition, suggesting alternative mechanisms of growth regulation.“
It is hard to get consistent CO2 levels from fermentation. I know this for a fact, because I did it with aquariums, which has some overlap with Cannabis growing but growing plants immersed is a bit of a different animal. It’s fine for very small tanks, I guess.
You are going to drop your pH at the root zone from Carbonic acid, probably a full point downwards. It’s not gonna work. I’m just telling you to avoid wasting your time. You’re gonna have far better results sticking with the fundamentals of the incredibly simple hempy bucket than trying to make it a Rube Goldberg machine. Air is a far more effective way to deliver CO2. Root uptake is minimal.
If supplementing CO2 to the root zone was so great, why don’t any growers who actually use pressurized CO2 use it in their reservoirs? It is important to master the fundamentals and then ask yourself “why isn’t this already a thing?” before you try reinventing the wheel. Get a few hempy grows under your belt then try fucking with the program.
Check out the (multiple) hempy bucket threads on icmag. Hundreds and hundreds of pages to keep you busy.
