Really nice thread .... such good help info offered, its nice.

I have the same sort of set up - buckets.

Couple key items I have noticed... 5 gallon buckets (depth) is amazing help for the root growth - plants are MUCH healthier and MUCH bigger... also a shared res. (even just another 5 gal bucket) makes keeping PH and nute levels at the right place easier.

right now I am fighting the cold in the garage and a cheap aquarium heater in the res. made all the difference.

carry on good gardeners....
