first a little background,
I have a closet grow, a small space, 2.5' x 2.5' x 6' (L x W x H )with 4, 42 watt cfl bulbs suspended 6" or so above my plants. I plan on growing 2-3 plants. i have a 50 cfm exhaust fan at the top of the closet, venting into another room with a carbon filter on the end of the duct work. the closet is not sealed there is about a 3/4" gap at the bottom of the door for air flow and 1/2" gap at the top. I am growing in soil, my own mix of miracle grow potting, organic potting soil for flowering plants,and a little perlite. as of now my plants are still very small, and are not in their final pots yet. the lights are on a 18/6 timer. my exhaust and air circulation fans are on timers as well.

questions:

1. when making the switch to 12/12 i want to change the timer from its current setting, where it turns off as the sun goes down and on in the early morning hours, to off during the day and on at night, so the room stays cooler during the day. will this create any problems?


2. i have shitty city water, will this effect my plants? what is the effect of (city water v. well water or spring water) i am almost positive there is no water softener in my building, will a cheep Brita filter work? i can obtain spring water somewhere near by and would not mind the extra work if it will be beneficial.

3. should i install another exhaust fan, or is the one i have gunna get the job done? should i install an intake fan from the other room to my grow space?

4. is my lighting adequate?

5. is a 50/50 MG potting, organic flower potting soil mix ok? is there any reason this would cause me a problem?

an answer to any, if not all of these questions would be greatly appreciated.

sincerely,

spector
