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.
  1. If your saying you want to have the lights running at night, then that's is fine. Only problem is you will be sleeping so you won't be able to really check on them to make sure they are ok during the day light hours.
  2. I usually don't worry about the water too much. I just watch for the PH. Go to Wal-Mart and get a PH test kit for $5. What is in the water probably does matter, but I don't have that problem here. Maybe get some distilled water or do some reverse osmosis.
  3. Depends on how hot your grow room is. 75-85 is recommended. Never go above 90. Maybe you should do a dry run of your room to see how hot it gets when the lights are on.
  4. In my opinion 4 CFL's are not enough. I'd go with no less that six, 42W...I have 10 23W (1600lumen) bulbs on 3 plants right now and they are starting to get hella-bushy. I will probably put in at least 2 to 4 more in there when I get ready to flower. Remember also that when you add more light it will get hotter in the grow cab/room. Also, bring those CFL to about 2''-3'' instead of six. Also if possible, put them at an angle rather than hanging straight down. Will get more usable light that way.
  5. You can make any potting soil work. Just have to "tweak" it to work for you. Many dread that MG stuff, but it has worked for me! My first grow I had MG garden soil and used MG fertilizers (never again though; i upgraded :smokin: )


Good Luck and Happy Growing
