Fact fans underneath plants cause huge growth spurts..

[willyweed]

sounds like your grow envroment is more dialed in then other persons. fans set at different levels in the grow help to move air around inside fans blowing onto the plants help to build stronger stems. fans blowing in the garden like in mine help to dry out the medium much faster thus allowing for more waterings and feedings

fans dont creat CO2 but water, sugar, and some yeast will

yes they do and just watch the plants near the bottles of warm water sugar and yeast grow bigger than the others $2 week in a 120/120/200
