im more than impressed with my diivoo watering timer. Roots Have exploded and are very hairl, most ive ever seen since installing the drip system. i have switched it to feed every hour for 3 minutes now and start by only filling the 5 gallon buckets half way with plain water with a ph of 5.8. the acis working wonderful. keeps the air at 75 degrees and im able to keep solution temp at 65. i moved my led lights up to 35 inches because i have my 600w metal halide light on now also.
