First Time Grower, Need a bit of help.

hello mates, i kinda agree with all of you, i think if its your first grow then start at the bottom cos no doubt ya gonna make some mistakes, tubes are great for clones and young plants but i dont realy think they pack enough punch to thicken the buds towards the finish, however you can grow with them, i personly would go with a 250 hps all the floors, walls, and ceilings i would cover in tin foil,this would not only reflect light around the plants but would protect the wooden cubard your using, a small osilating fan would cool and cerculated air,you would of course have to make an opening to allow fresh air in, and if smell was a prob then you should vent it up a chiminy all the best bro,

Mylar for cheap: walmart, emergency blankets, in the camping section. $1.96 4' 4" x 7'

yea well if its in a closet, you dont need a fan or anything for the amound of plants you are planning, you just need to open the closet door for 5 min every day.
And no mather what ever growers say, in my experience tin foil is way much better than white painting...
so good growing
