So I had an idea and was curious if anyone has tried this or if it's even feasible. Im attracted to the idea of 2 liter hempy grows but not so excited about hand watering every other day. My thought was flood and drain trays stacked with 2 liter bottles cut the usual way for hempy. If the timer was set to flood every other day would this work instead of hand watering? Just an idea I thought might work well for a relatively low maintenance grow. Any thoughts would be very appreciated!
