How does this setup sound for optimal yield

- Currently have 12 plants growing in a closet (Master Kush and Bubble Gum Kush). Long and rectangular in shape. Trying my best to describe what me and my wife did so far.

- I believe we have a total of 800 watts of light on the plants....using metal halide? the room is BRIGHT.

- Set on a timer

- Covered wall to wall in black tarp to keep the light in (and the light out when the timer goes off)

- transplanted in the best soil we could find

- We biult in ventalation with fans (bought the good ones when we got the seedlings) and a in and out exhaust to the room.

- Has a temp and humidity guage that we check constistantly

- We only spray the plants with the same drinking water we buy for ourselves at the water store.

(MH) METAL HALIDE LAMP - A high-intensity-discharge lamp in which the light is produced by arcing electricity through a mixture of metal halides. The light produced by metal halide lamps is in the white-blue spectrum, which encourages vegetative growth and "bushiness" while discouraging upward growth. This is the bulb to use in the first, vegetative phase of plant growth.

Black tarp facing out you should have white facing in to reflect the the light.

Do you know what temp and humidity level to check for?

You need to ph test all your water. You can get a cheap kit at Home Depot for around $10

You set your timer for what? 18/6 12/12
