Hello guys! This is my 3rd grow, and this time I'm going to record it all on here. My first grow was 3x OG kush and 3x barneys blue cheese - in coco and under 600w hps, yield was 12oz dry. 2nd grow was 4 blue cheese clones (15l pots, coco, 600 hps) yield was 18oz dry. Now I've just cracked 15 Critical kush seeds, and I've bought a lovely new T5 4ft 8tube for seedlings. I will use metal halide thru vegging and then hps for bloom. I'm using coco/perlite mix at 70/30. Tent size is 1.5m x 3.0m x 2.0m. I'm wondering how much light I will need through vegging and bloom. I'm thinking maybe 1500-2000w?? The strain info says 750g per m2, which would be over 1500g. But then on my last grow I achieved 0.75g per watt. How much light will I need to maximise yield? Any questions, input or advice would be most appreciated Photos of last projects as well as pics of this current one will be uploaded soon.........
