any feedback or suggestions would be appreciated... this is my first attempt and i'm planning on building a small box to Scrog a small amount. the box i've built so far is 3 ft H x 2ft W X 1ft D(not much space i know,but i really cant go much bigger than this at the moment)...i have 1 intake hole,1 vent near the top both aimed slightly offset from the light so i can control lamp heat a bit easier, and also a small oscilating desk fan mounted and aimed towards the plants.i'm thinking a 70w HPS would be fine to start with for now.being that the box is only 2 sq ft,and the 70 w hps i have gives off 6300 lumens,which would give me 3150 lumens per sq ft.(hoping i calculated that right!)hopefully maybe someone can point me in the right direction with a timer set up and power supply ideas,i'm open to any suggestions...thanks!
