NOTE: When using with the GOLDEN ARM less slack is needed as the greenhouse length increases. The additional slack is needed to cross over the greenhouse diagonally.

Size Your Tarp guide is intended as an aid for measuring for your greenhouse blackout tarp. Please take great care in measuring each dimension to ensure proper tarp size. If you have doubt about your measurements, remember that having a tarp that is too big is easier to remedy than having one that is too small. Harvest Excel does not take responsibility for incorrectly sized tarp.
