second attempt. # nirvana strain grow

This is my second attempt. The first 1 failed due to not checking the PH and putting my seedlings straight under my 1000w MH. well learned from that and here i am again.

I will be using the spare room as my grow room. They are in the corner with the back of a wardrobe as the third wall. I will line the walls with mylar and have a A/C directly above the grow area.I have a 1000w digital HID with both MH & MPS bulbs. I have read 4x4 will give me the best results under the 1000w so thats what i will do. Inside the wardrobe i have 5x 24w (6500k) cfl's. How long should they stay under the cfl's before i can put them under the 1000w Mh?

I am doing a soil grow and working with 3 nirvana seed strains.
1. Blackjack
2. Raspberry cough
3. Super skunk

I have 9x 2" seedlings under the cfl's at the moment. What is the optimal number of plants (for yield) i should put under the 1000w?

I am sorry if i left anything out. New to this. I would be happy for any advice and suggestions you can give me to see this second attempt a successful one.

Holy Fuck!
