thanks for the info man. can never have enough knowledge. but i do have a 250 watt metal halide by hydrofarm. i have used it in the past with great success. I did a lil sea of green. I did get my lights all installed in my box and am germinating tonight. and planting in a few days. i do have experience with different methods but i never have topped a plant before. when is the best time for the size of my box. i know how to top plants. just never done it. i also know how to do clones with a mother. should i do that. keep a nice fat bushy mom in there.
