I may have got a little gun shy on overwatering. I don't want to underwater and leave for work on a hot day to come back and find my plants dead. I know you have to factor in the different variables, but what is the normal amount to water your plants when they are in 5 gallon buckets each time they need water? I know you need holes for drainage and I have plenty but when I water, it never comes out the holes. I feel as though only the top few inches soaks up water, so that would mean the roots way down aren't getting water. My plants seem to be doing well but as they grow I'm sure that water needs to reach further down. Tonight on one of my plants I must have put in 2 gallons of water and nothing had started coming out the drainage holes. The mix was very dry before I watered. I'm using ProMix BX. I stopped so I didn't overwater the rest of my plants in case I did one.
