I do have one quick question though. I'm wondering why you are using the plastic tub for. Is it for humidity related, or to catch water run off? Just curious, no real reason, lol...
The tub transports the plant from where they live around the house to the sink and back. Saves transaction time. That's it.
Now, why haven't I thought of that........ I carry all mine by twos in my hands. (I guess I could claim that doing the upstairs ones keeps me fit as I go up and down I don't know how many times!)
