the tipping thing is a very good point. I am concerned on my pipes over that and think I am going to clamp them down with 2 hole clamps.
You also bring up a valid point I have been contemplating and that is how long do you leave the roots it is a balance and I will be in a
drip system instead of a flood and drain so the real question is how much water and roots are needed to maintain a good growth. that is why I am playing with cherry tomatoes easier to change setups and quicker response time form the plant.
