would you need separate ventilation fans for both spaces, or is it possible to vent both with one fan, and two filters?
This would be possible;obviously you would need a tee and the filters would need to be close to the same size. So one wouldn't overdraw the other one. This could work fine though you might run into other problems balancing your grow environment.
I was looking at this tent, and it seems great for perpetual grow, but I'm just curious about how many pounds the bottom level can hold up? I plan on getting your 400 watt "high performance package", Along with a 6" inline filter and fan. I was wondering if the bottom level can handle the weight. I also will be putting a 250 watt Feliz CFL on the top for veg, along with two fans for exhaust and intake.
The tent is rated to handle right around 90lbs (40kg), with this in mind I think that it should be able to hold the weight of the equipment that you are going to be using.
How does the construction of the Secret Jardin Dark Room Pro DR90 II Grow Tent compare to that of the Secret Jardin Dark Twin DR90T?
The Secret Jardin Dark Room Pro DR90 II Grow Tent is 7.8 inches taller than the Secret Jardin Dark Twin DR90T and has one compartment rather than two (propagation top/bottom).
Is the floor of the Secret Jardin Dark Twin DR90T's top level as flat and stable as the bottom of the grow tent?
The top floor of the Secret Jardin Dark Twin DR90T is just as stable as the bottom of the tent and I definitely recommend it!
All in one grow station: Mother Plant, Propagation, Growing and Flowering. Allowing three possible configurations:
