yea just dont have it real close, like u would with cfl's.....i put my seeds in paper towel and put the paper towel ona saucer with seran wrap over it, run fresh water over it daily and when they are sprouts out of the shell, i put em in dirt under my hps cant afford T-5s right now but when i can i will be using that for vegging but hps works just fine....make sure you have a fan in there tho....

yup you got that rite...took me a while to get that threw my wifes head lol.....but after the first harvest she was like oh yea! lol......as for supplying oxygen to the plants u have to have your intake at the bottom of your grow room opposite your exhaust (exhaust is gonna be up top if u didnt already kno that) i have a 4 inch exhaust and a 6inch intake...hope this helps ...

intake isnt as important....the exhaust will suck air from all ur openings....but for an optimal setup and optimal harvest, u will want one

no its not but when i had my intake the same size as the exhaust the temps were running almost ten degrees higher.....having an intake helps alot, but i built a box too tho so there arent many othere cracks or holes lol

oh yea the temps will drop alot more than they are...i added a 165cfm fan from hydrofarm with a speed controler and i dont have the speed all the way up, my temps use to be upper 80s even got into the 90s at times now they dont get above 78-79.....so i think your temps will drop for sure

thats good to hear then mate, will the plants suffer if i dont get an intake? or will it be fine ?

well depends how "air tight" your grow box is, if its fairly air tight and not much air gets in then you wont notice much change in temps thus harming your plants (heat stress), if its not as air tight and it sux enough air threw it then u should be fine....

right on, you may be fine...you might have to experiment with it a little like i did till i got mine perfect, i finally got fed up with the high temps and did alot of research on passive intakes and such and then i finally just cut my intake hole bigger thats when i was like oh yea thats better lol

lol i think thats all im going to have to do, well il get my exhaust fan and pipe this weekend hopefully see what difference that makes, then if its still to high il have to get a intake, because i think it gets enuf oxygen when i open the door to look at the plants etc?
