yoyo mulletman thnx for the comments. yea my intake hooks directly up to my light hood so the fresh air is dropped right onto my plants. also the outgoing air is connected to the hood as well to take away some heat and smell. im not doing anything yet about smell but in a few weeks ill take the outgoing duct off the hood and hook it up to a carbon scrubber. with the fan on the temps under the light r just warm. i can easily let my hand rest under the bulb without feeling a burn. also ye i drilled a lot of holes into the bottom of the buckets. i see you did the same as i did, upgrade your 250 to a 400...my plants love it. as far as nutes go, yes i am planning on using them. i just dont have them yet lol, im so mad. i ordered fox farms whole line of nutrients and im going to follow their feeding scedule chart. i ordered from BGHYDRO.com 2 weeks ago and they just shipped it a few days ago. it should be here soon. im sure my plants will love it. anyway let me know if u got any more questions or comments. peace n pot bro lol
