Just moved my two plants into the loft, all seems ok, i've got them under a 125 watt envirolite, probably add a couple of small cfl's when they're bigger. For ventilation i've got a bathroom extractor fan blowing air out at the top just passive intake though the floor for now. Temps are 26 C now but i need to check them at night to make sure it doesn't drop too cold. Gonna start the nutes tonight, using Bio Bizz's Bio-Grow, think i've left it a bit longer than i should, was going to start at two weeks but forgot due to being busy building my new grow space. When does everyone else start nutes? Here's a pic to show the progress in the last week. :rasta:
