Thanks for the help!! I guess that I will be going with 2-400 watts. I put a picture of the pH meter I have. Do you really think my babies look good? They seem healthy to me, but they seem a bit smaller than average...but, thanks for the compliment! Like I said, I read the instructions to calibrate the pH meter, but I'm kind of lost. Not too sure on where to purchase the buffer solution. I'm going to check my local store for some solution.

1. I would like to run two separate setups (10-Early Flower and 10-Late/Harvest Flower). 20 clones shouldn't be too much to handle. What type of Hydroponics system would someone use for this plan (2-400 watts MH/HPS, two separate setups containing 10 clones each)??

2. If I put the drip rings down, would the roots be able to get enough water? I believe that the root system is still too small to be fed by the drip ring, but I'm going to give it a try.

3. I have two types of nutrient-trios (GH 3-Part & FoxFarm Trio). Which nutrient brand would you use to start off with?

4. Could I use General Hydroponics pH testing solution to adjust some water close to 7.0, and then calibrate my pH meter using the adjusted water?
