My grow room is 4 ft by 8ft with 4ft by 5 ft used for growing. I only use the turn table that is in the picture during LST and have a second small room for the 3 autoflowers while the 3 OG Kush plants will cover the growing space using a two level scrog. I put both my 1000w full spectrum and 600w up when I started this grow (only my 3rd) just for the hell of it. The smaller light is for the smaller room, but I am considering putting in either a Mars Hydro 3000 full spectrum or four 600w Mars Hydro TS in the main room. The obvious choice by wattage is the 3000w since it is the same price either way, but I think I will get wider coverage with the 4 lights. Picture is from week 4 and the larger leaves are the regular feminized OG Kush from Crop Seed King. Thank you for the help!
