Strong zippers
Lots of different openings for venting and electrical
Tent height
Availability of CFM poles
I kinda wish that you guys would offer a more upscale designed tent with attention to the first three factors.
I think tent height with your tents is the biggest limiting factor. In the 2X4 tent, I'd rather see a circular opening at the bottom on the right and left sides instead of the velcro flap covering the screened opening. I don't use that style of flap on
any of my tents for induction of fresh air. It's just too much work opening them up at first light and then closing them with lights off. For proper air flow in a tent, the majority of cool air must be drawn in at the bottom and exhausted out the top. In your 2X4 tent, I have to bring in air with ventilation tubing at the top openings on either side and bring them down to the bottom of the tent.
In this Mars Hydro tent That is powered by a SP3000 and far red supplemental lighting, you can see the Ventilation tubing bringing the cool air into the tent and down to the bottom of it.
You can see by the picture that the girls enjoy the environment quite well and hopefully the tent height is not going to come into play with
another failure of a dimmer switch with this light. it's on full blast all the time! Hopefully you guys don't use the same dimmer on your new models, which I don't think you do. I'm not the only one that has had problems with that exact same model and dimmer.
