You have landed on one of the most controversial topics on this forum. Everyone has a system that works for them and if you're happy, it's the right one for you. I am growing in 3 gallon fabric bags. During summer It gets over 90 degrees in my tent for days at a time. This causes a lot of evaporation through the side of the bags. I have 7 plants that get 1.5 gallons every other day at 50% nutrients. This seems to work as the plants look good and I have only very minor nutrient burn. In winter, I may do two gallons every third day. My last two watering's before harvest, I only provide plain water.
