from what i have been able to tell, it takes a few weeks before the plants start changing the way they grow. at some point they get stuck in a vegetative state where they constantly grow, usually in slightly different ways than they do with a normal photoperiod.
for instance, a plant that normally grows very dense leaf clusters will grow incredibly leggy, or vice versa.
anyway, i have been lazy with taking pics of the tank because i have neglected it to the point where i couldnt see clearly through the front glass.
before i cleaned the glass, before the massive trimming.
after i cleaned the front and after the massive trimming.
this is the tank on november 25th. it was still recovering from the move across the country.
september 23, right after i filled it back up with water after the move.
the day before the move:
during the move. had i room to turn the tank sideways, i would have been able to save more of the plants i think...
just before the move, at the beginning of october:
the lights are just 48 inch dual bulb shop lights from walmart. there are two of them on the tank, for a total of 4 bulbs.
