Did you watch any grow vids or read any books yet? If not your going to be running around like a chicken with its head cut off, trying to figure out what to do next. Not the place you wanna be is it?
Your blue 125 thingy... I'm guessing that's a big 125w cfl like an envirolite or whatever you call it. It should work ok for vegging (the first stage) because for vegging it's said that our plants like emphasized blue light. For vegging the light cycle can be from let say 16 to 24 hours of light per day, it must turn off and on at the same time each day so it's good to have a timer. Also it has to be DARK when the plants are sleeping. I do 18/6, 18 hours on and 6 off each day at the same time and it works well for me.
Water your plants throughly and make sure there isnt any dry spots or dry pockets in the soil, then pick up the pots and get a good feel for the weight. You don't need to water again for a few days, pick up the pots and when they feel light they need water and you repeat the process.
Now you need to sit back, roll a joint, and watch some grow vids if you haven't already done so. Don't forget to read the
GROWFAQ , use the search, and check out some
Marijuana Plants | Marijuana Leaf | Grow Journals to see what other are doing.
Good Luck and Happy Growing!
