11! i hope they r small. but those lil UFO's dont do much, u might as well put them an the walls pointing to the side of 1 plant, or even on the soil pointing up! they ARENT much tho fer power, the 400 is wats gunna do it.

Two different
2 x 400 watt chrome dome grows. Check out my albums evil.
ANYONE use these? I have great results everytime using them. Less heat, better spread, no hood. averaged .7 grams a watt. good for some 400s.
3 plants seed to flower 45 days
currently 5 seed to flower 30 days, expecting same results.

hi all heres an update im on week 7 flowering now there doesn't seem to be any difference in the veg stage between the two light types but the flowers are different in the way that the main top bud cola under the hps are taller and narrower and the colas under the led are shorter and fatter does this make any sense this is my first grow and i am using canna products and growing in coco coir i will post pictures tonight so if you guys can let me know what you think.

I would keep the 90 watters. HID guys do hate on LED's for the most part, but I understand. I mean, hps and mh = big harvest, so why change? But IMO the led's are better watt for watt. Now when i say that, I do not mean that a 90 watt light actually replaces a 400 watt hps like most companies try to say, rather a 90 watt led is more powerful and efficient that 90 watts of hps. I would consider running all LED lights, if you can afford more UFO's. some are on ebay for 150 with a 630nm wavelength which is what you want. If you were to run 8 of those, you would have a KILLER harvest. Your bill would also go down and you would have more control with your light setup. I think anyone living in an apartment should consider LED's because they do not produce heat, which I find to be the biggest cause of smell during late flowering. Just my two cents. :leaf:
