Whats a Cheap and Easy way to make CO2??

LOL! Lucky coincidence.

just have sex near your plants

I like Harris7's comment, except the only place you could do it around my plants is up against some fiberglass :(

Does it actually work to just open a canister of co2 from a bb gun and spray it on the plants twice a day?

if done at the right times and amount id say yes! :) you can use 2 much co2 though! the plant cant take it in. there’s a certain mix of parts per million that is ideal for the plants! :)

Air (nominally 80% nitrogen, 20% oxygen) and Carbon Dioxide are completely miscible in all proportions. Although it's heavier than air (air has an average molecular weight of 28.8 vs carbon dioxide's molecular weight of 44 -- so it still dissolves in air and can be dispersed throughout the atmosphere of the world

ya,i know....but hear me out....get a 1 gallon plastic container,put enough co2 ice,and water in to start a reaction,cap it...have a small diameter hose ,run it to collection chamber,(preferably above your lights(to warm gas)or you can just let it sit til warm(rm temp)...i've done this with zip lock bags(makes a pillow bag)and squeezed the results over the plants...i know ,sounds stupid,i have no idea how much c02 these plants need:wtf:...i guess any they get, is better than none...maybe ,i'll have Mrs desertdweller sit in front of them and yak away for an hour a day:D

I am new to indoor grow but I have a ? suggestion- isn't dry ice formed from c02 if so how about putting a block in your passive air intake- or is it too heavy to be drawn ito room by extractor fan?
