im growing a couple mothers in a very small closet 3 x 2 feet 8 feet high. wuts an easy way to supplement my plants with the co2 they need?
do you mean with brewers yeast in a 2 liter bottle? he could possible get the ppm high enough to have an effect since the space is small. possibly... ive never measered the amount/rate of co2 given off by yeast? has anyone?all that bullshit 2liter bottle shit is pointless in my opinion
it will very hard to increase the ppms to 1500 of CO2 using those methods with so little release of co2. folks who claim to are something like placebos and such!!!
