ONLY use a mag drive pump as the other after time the oil leaks out. I have used on mag drive pump for over 8 years and no problems yet.
A word get a ph and ppm meters so you know what your putting in you plants. The best will be the cheapest in the long run.
Keep it clean and calibrated, and have fun, and never tell anybody that you grow. # 1 rule of growing #2 duck tape works the best for keeping ones mouth shut # 3 see 1 and 2
you also want to time your pump so you only have 20 minutes three times a day. Soggy roots rot, nothing worse than a wet bottom.
