So as my first post i just wanted to share my set up. Everything is clean and fresh. First off we have... A 4x2x4 Veg tent with a Four foot 6 bulb T5 with all 6500k bulbs A 90 watt growco LED ufo (nothing to special) just rounds off that spectrum. for air we have a 6 inch inline fan pulling air into the tent at 270 cfm and for exhaust we are pulling air out of our little veg tent straight into our next topic... A 4x4x7 Flower tent with the VANTECH 6" 470 cfm inline fan as previously stated, its pulling air in from the veg tent. ( most likely have co2 pads hanging in the veg tent.) As for lighting we just set up our brand new MARS II 900W led fullspectrum surounded by our original KESSILL H150 KESSIL H150 magenta x2 KESSIL H150 BlueW x1 KESSIL H150 REDW x1 And we can't forget the Good ole' GL300 LED panel, a full spectrum panel with flower emphasis (heavy in the 610-700nm range) In total is 1800 theoretical watts OR... MARS II 900 (400 actual watts) KESSILL (36x4=144 actual watts) LG300 (180 actual watts) Weighing in a 724 Actual watts. And for exhaust we have a 6 inch scrubber hooked up to an 8 inch inline fan pulling out approx 400 cfm a dehumidifier, a couple ocilating fans to play around with i have a 6 spot hydro/aero convertable table system meant for learger plants. along with a nice (if i may say so myself) 44"x44" screen of green net that i can adjust from 30"-48" I'm inbetween grow and looking for some advice as to what i need/ what i should fill this baby up with!?! any idea? any constructive criticism?
