I realized last night that my two large plants were strangling each other and I was seeing the strongest survive and the weakest die a slow and for me, painful death, so I cut the roots to the weak one and discarded it then placed the other plant, the small one, as far from the big one as possible. No repeats necessary for this lesson. I'm going to be looking at others who have diy'd their own systems and make one that won't repeat this problem. Both remaining plants are staked to prevent overnight falling over so I wouldn't have any more unplesant surprises. Anyways, I think that fixes that one. More space, no aerogarden, more air and more circulation should fix the problem as well as staking the plants before they could possibly be tall enough to fall over. It's been a learning experience so far. That's good. Now it's time to research more.
