I just cut excess poly on mine, which isn't much.
Both the ends and sides share the same deep SLB, since yours is a hoop then cut to shape.
That way it fits more snug without slack like it's being pulled and rolled up like toilet paper.
In addition to that, it does ruin the visibility of the sides if you're from the outside looking in, vice versa.
My setup is a bit automated, everything is digitally managed with a controller I installed.
I programmed several outlets to do the following:
- Exchange Fan (if x then x fallback off end)
- Ball valve propane feed
- Electric fan forced heater
- Mist system when humidity is below 30%
- Fogger on (if temp1 >55F switch on)
- Dehumidifier on when 90%
- Emergency shut down due to moisture
- CO2 >1800 PPM cycle Exchange fan
Wind and pressure notifications when it reaches 20mph so I can remember double check the logistics of the greenhouse.
Many cool things to do to adjust and control the environment.
Been working well since my rambutan, mangosteens and langsats are doing ok so far...
I'm an analytics kind of guy so looking at the graphs and such does help predict and anticipate adjustments to the microclimate.
I suppose it may be a bit redundant but when is it every enough?
