I have 3 female clones that i have been vegging under a T5 HO and 4 23 watt CFL's they are now about 13' tall and im planning on flowering them under a 1000 watt HPS that i got from a friend for free. Will that strong of a light burn my plants? Will they stretch too much? I grow in Soil
3 plants, 1000 watts, average gardening procedure, you should most likely see over a pound of dried, badass buds . im thinking 5-8 ounces per plant when all is said and done. edit- re-reading your post i now realised you are growing clones. i know nothing about clones and how they grow compared to plants grown from seed. may be a difference in yields and quality, but really, i dont know or care. good luck.
wow more than i expected off of 3 plants. Ill share the final yeild when i have it im starting flowering in a week
ya that much light and only 3 plants... i would do some extra long vegging and lots of training untill there canopies can cover the whole space you could get a monster load of buds off a lady with the right amount of TLC they will veg just fine under the HPS too
If they are 13' tall then I think you vegged too long. Sorry I had to Anyway, like Jones said, as long as you can vent out the heat, the more light the better.
