yeah but you cant do it if you have a fan pumping air out cause its just a wasteEh clowdy the home made c02 is simple.
you will need a 2 litre bottle some active yeast, sugar and water. You add 1tbs active yeast and 2 cups of sugar to 2 litre bottle and fill the 2 litre up with water about 3/4 full and shake it vigorously and vualla you have home made c02. The c02 will not start until 1 hour after making the concoction and last anywhere from 1-2 weeks.
Defintly more effective during flowering and no you need to turn your fans off. The best times of feeding c02 is in the mornings and evenings when the stomatas are open. Although, the homemade version is always pumping c02 and can burn your plants if the lights are off, so keep an eye on it.....yeah but you cant do it if you have a fan pumping air out cause its just a waste
it is more effective in flowering
Umm..ok , but why? I've noticed that until the lights have been on at least an hour, there is no gas being made due to low temps..Lol...........
The Scary Clown said to remove bottles when dark I wondered why. i've noticed when cool, co2 production slows..ever tried to have bread rise under 90d? No happen!!, Hungry yeast doesn't like cold, so it stops eating= no co2. Also, contrary to pop opinion, co2 RISES above 75d so put the nozzles under the plants..ur talking about witht the lights on/off another?
