Great write-up on the tents by the way OP. :thumbsup:

Personally, I would choose the newer GrowLab tents for many reasons including their IR blocking highly reflective inside material and updated features like built in vents with drawstrings / covered viewing windows / most frame weight capacity for holding equipment / ability to just set the exhaust fan on top of the tent instead of mounting it inside and much more. From what I can tell they are the best on the market and virtually lightproof.
