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.
