I agree 100 percent red and blueThe price notwithstanding, I agree with Tree?? - the dual-spectrum 1000w does rock. You can run a 600w HPS and a 400w MH simultaneously or individually. The next best thing to the sun!
I appreciate the question. I'm not qualified to answer it, I have never used cfl's. I believe they can do an excellent job of not only vegging but flowering as well. I just read a book about it. Guy grows 8 oz for less than $100. pictures of the three plants every day for like 69 days, amazing.Also, you should ask VictorVIcious about vegging with CFLs and then flowering under an HPS. There are a lot of options, prices, and advice but only you can tell what is going to work within your space and budget.
The best 1000 watt hid light for the money is 2 4'-8tube t5's. VV
What is the best air cooled 1000 watt HPS complete light system for the $???
rip, my 820mm^2 trays hold 23 pots each.
Yes, I noticed that. I thought they were 4' by 4' tables and was always confused as to why I could easily put 20-8" pots on my table that is 32"(app. 80cm) by 48" (app. 120cm)
I have 4 trays in the flowering area, each pair of trays has a 1000... so the short answer is about 46 plants (with SoG pruning and flowering as soon as your cuttings have got a good spray of roots) under each 1000.
