Here's 3 plants that I've been growing under 400 watts hps they're 7 weeks old and I just started 12/12 since they've gotten rather large used fox farm ocean forest and canna terres nutes the tall one is White widow while the other two are some indica blend that I can't remember at the moment
that white widow plant is going to produce so many fuckign buds. you should get another light to make it really pump out the goods, put it on the other side.
There already pretty damn tall.. you need a stronger light or more lights that 400 isnt gonna reach the bottom too well
the two smaller plants are biggie smalls from dr.chronic, had them sitting in a drawer for a few months and almost forgot they were there. I just got another 400 watt sun system metal halide ballast and reflector off ebay for $70, think I should hook that up too? and how much more would that cost me on my electric bill? I'm not all that worried about cost but I'm kind of curious.
i doubt itll be that bad. whatever it is, you'll make it up in how much more bud you'll have. good call on the extra light.
