i just looked at your journal and i would say definetely keep to the HPS. my LED dont compare to 1k watt. but in response to your question, they dont emit almost any heat. they came with three built in fans made to cool the whole thing. i dont have a therm in there to check room temp so i couldnt really say what the increase is.
if you have ALOT of heat issues and the A/c's that you use aren't keeping up or it's runnings your pockets thin . Look into some CFL's. They produce with out as much hassle with heat .Envirolite is a big hit in the CFL technology. check them out.
In most cases that I HAVE SEEN , they tend to do that but produce a nice stash if done correctly
the UFO is like 60 red and 30 blue i think or something like that. And if your judging the stretch off the plant in the front then take a look at the others. the one in the front is a ww which is sativa dom and im trying to contol the height so it doesnt get too stretched for the others. all of the others are within 6 inchs with lots of growth.
ya width and lenght wise im pretty much out of space but plenty to grow up. i was supposed to flower sunday which would have stopped the need for space but with the one light being out of commision i gota keep them in veg for alttle longer.Those plants look happyOnly problem I see is that you mightrun out of space...
HID for now but one day i think LED may catch up
