i actually got everything except 2 of the fixtures and the warm-white bulbs for free. i paid about 25 bucks for the entire lighting. that's the main reason i didn't buy an HPS. but i didn't know HPS were needed for deeper penetration. i just thought it was about how many lumens you have. but...

i have 10 4' flouros. a mix between grow-lux, cool-white, warm-white, and daylight bulbs. i have an intake fan and an exhaust fan. oh, and i have a compact flouro, i think about 20 watts, above the plants.

okay Al, i see your point. but let's say i have 4 plants growing in this space. they're about 2-3 feet tall and started flowering a week ago. what would be the best pruning strategy in this case? would i really need to cut anything, since almost all of the plants would get equal amounts of...

also, sea of green requires a lot of floor area for the grow. i have limited floor area but 7 feet of height available. i don't think i should trim the bottom half of the plant if it can still get light from the sides. that's the real reason to trim the bottom, or am i mistaken?

So I thought it was the pH. I did a flush while I was waiting for the test kit to get here. That didn't help. Also, it turns out that the pH was correct the whole time (unless the flush fixed it). It was between 6.5 and 7. Everything I've tried hasn't worked. I tried folair feeding...

yeah, I was worried about that. I ordered a pH meter and the stuff to adjust it a few days ago. It should be here this week.

what do you mean? I water them when the soil dries out, and I water until it drips out of the bottom. It hasn't gotten too dry for any length of time. Could this be caused by overwatering?

Hi. I was hoping one of you could tell me what is wrong with my plant. Pics are attached. I germinated the seeds 3 weeks ago, and then planted them a few days later when they sprouted. I put them in kind of small pots, hoping to sex them before transplanting them into the larger pots, as I...
