very good idea to keep temps down in a small space without a cooltube +rep for that
maybe a scrog net would up your yields alot, have you thought of that?
so today as i was taking my last hit from the bottom of my stash(mostly kief), as i was about to pull it through it sparked and sortof like had a mini explosion. wtf could cause this?
backintheday everything was based on experience and luck. if you have no experience growing a strain there is no way to harvest at the peak time without a scope.
would be nice to add some lower in the canopy to supplement light. more light is rarely a bad thing. that is if you can keep temps in check.
to really determine if it is worth it you need to find your limiting factor(whats holding you back from more yield) and if it isnt light then it wont make...
