1. Transpiration is limited by an application of AntiStress coating which forms a semi-permeable membrane around the leaf and stem surfaces.
2. The protective coating only partially blocks the stomata...

Sounds a lot like an anti wilt to me, but if they insist it's not, maybe it isn't. I was under the impression it would limit transpiration, and then I read the above and my suspicions were confirmed. I was always under the impression that you wanted as much transpiration as possible, or at least I was pretty sure blocking stomata is bad. Isn't an anti-wilt or semipermeable membrane a temporary fix? Along with dealing with spider mites once per week instead of just fixing the problem?

About the clone tubes, normally you want a slit down the length of the tube. That way you can just pry the tube apart, but still use it next time. This is one reason I recommended working the professional replacement neoprene inserts into your design.
