Aqueminianswered grow question 3 years ago I honestly think running LED and CMH at the same time thru the entire grow gives the best quality.
I'm running 2 TS1000 full spectrum white and red and a Growers Choice Master Pursuit 500w CMH with a 3k-R bulb.
Total of 800W. Plant size increased a lot. Plant strength increased a lot. Everyone says yields go up and get better frost and density. I'm still waiting for my first harvest so no opinion on finished product.
Check out my OG Diesel Kush autoflower diary, I under fed her but she is turning out pretty impressive for an under fed autoflower.
Also this would be a great setup for anyone doing a scrog. The stems get thick quickly and get semi tall quickly, but once it gets closer to the LED lights it stops going vertical so much and starts building tight node spacing.
I'm going to finish off my 10 plant perpetual and switch to a 4x4 scrog with photoperiods and try to pull maximum yield.
