Dual chambered grow tents

Hey everybody, long time no talk.
Anyways I'm wondering if anyone knows of any dual chambered grow tents that allow air passage between the veg and flowering chambers. I'm wanting to use 1 can (inline duct booster) attached to my cool tube, to vent out both grow rooms. I'm wondering if the inline with be strong enough to do it. (likely if there is a direct path)

What I don't want to do is have to connect tubing on the outside of my grown to route the cooktubes air intake from the veg chamber. If there was a grow room with interconnectivity (but a light trap) I'd be very happy.



Also, what is the story with leads, have they made any progress? What would you recommend for my mother plant? A single cal, or whatever is cheapest is what I'm thinking. Prices have really come down, anyways.



Additional questions, I'm thinking of going 400w high pressure sodium in a 3x3 tent, I'm wondering how many SOG plants to put in, and in what sized pots. Also, there shouldn't be any veg time, and am I supposed to lollypopp the plants?





Thanks

I essential don't know how I'll vent the chamber with the mother plant.

I don't know of any tents like that.

What I did was set up 2 tents and run duct work from the small tent to the big tent with an inline fan and a diy light trap. Then I just pull all the air through the filter in the big tent for exhaust.

For a light trap just get a cardboard box and cut holes to fit your ductwork on either side, then add staggered step panels in the box so air can move but light won't. Works like a charm and costs nothing to make

build your own, it's not very difficult. duct booster fans are very lame, not sure if that's what u have....

They are quiet, and generally sufficient.
