Closet Grow-Room Setup - Advice?

I'm posting some pics of my future grow room - looking for advice.

Dimensions are approx 5x3x8.5 (w x d x h).

The plan is to install insulation in the room, then cover that with white visqueen. There's a hole at the bottom right, which leads to the crawlspace around my tub. I'm planning on making a vent hole there, & running ducting to that, sealing the crawlspace off with insulation once set up. There's also some trim pieces around the 2x4 in the middle of the back wall - that holds a shelf. It's about 5'8" off the floor, which is where I'm planning on placing the fan & supplies - it's also where I plan to clone once I've gotten the hang of basic growing. I'm also thinking I want to put a board to be held up by the baseboards in the closet, installing insulation & a heating element to help control the temperature in the room.

Things I'm wondering about are:

- humidity - what's the best way to control this? I'm in the southern US and average humidity on a dry day is something like 70% right now - more in the summer months. I've seen cheaper products that are just dessicant in a bucket - anyone know if those work?

- lighting - right now I've got 4 gro-lux standard spectrum lights I was planning on installing. I'm wondering if I have enough light?

- venting safety - this is more of a safety question than a growing question - there is no sub-floor or anything like that in my home - I'm worried about cutting a hole in the area around the tub - don't want to make it weak & have it give when I'm in the tub ;). Does anyone know if I'm going to have this problem cutting a hole around the tub as it is now? (I'm including a closer shot of the crawlspace so you can see).

- heating/cooling - any suggestions for the type of heating element. Winters in my area start in Feb and end around late April or early May. I'm assuming for now all I have to worry about is keeping the plants warm. I have no idea what I a good solution is for cooling the room in the summer when temperatures go into the 90's+?

- anything I'm missing?

I appreciate any help you guys can give.

thanks,
J

Hey man, you sound like you're in the same basic climate I'm in.

I'm sure there is a wide spectrum of opinion on how much light to use there, and of what sort, but if it were me I'd probably go with two 400w HID fixtures.

As regards the Winter period, my room is not climate controlled, so I don't grow December, January, or February. Not paying to heat my garden, just break out one of the old vaccuum-sealed "in case of emergency" packs from the fridge to get me through the holidays. If you must grow in the Winter, and for a space that small, I'd recommend one of those cheap, oil-filled "radiator" looking room heaters. They can't start fires.

If you're going to cut a hole into the space below your tub for venting, I don't think a 4 to 6 inch cut is going to compromise your flooring strength. I would suggest that when you're done, you board/wallboard over everything though and seal that room up as well as possible to keep out pests, dust, etc.

As for cooling and humidity in the South during the Summer, I've never found a good solution for my situation. So, I only grow landrace equatorial and subtropical Sativas such as Maui, Kona, Eldorado, Oaxacan, etc.

Looser buds for lower mold risk, natural resistance to heat and humidity. If you ventilate 24/7, and if you circulate 24/7 with recipro fans and such, I highly doubt you'll experience any problems even in the dog days of Summer.

My room hovers around 90F day and night from around June to October, with the same humidity as outdoors, and no mold or other problems.
