1.5^2 = 2.25 sq ft
105 Watts / 2.25 sq ft = 46.6 watts/sq ft
you'll be fine.

Thanks man. I guess I should have just applied the formula. This is just my first indoor attempt. People talk so much shit about fluoros and I just want things to work out. I reread all the grow books at our local bookstore for the gazillionth time. Its within my grasp though now. Just reading about it made me start making weird little giddy noises. Anyways I love the new site. All we need now is an ongoing joke like the old cat piss/5-MEOW one to make thing complete. So if I had used my old Shroomery name would my ratings have transfered?

no, just the name. CFL's work, but they do suck compared to other lighting. Keeping moms and breeding under them are just fine though.

is there any reason why one could not add tubes to the sides of a box to try and get light in to the lower areas of the plant? or will this make the plants grow all funky?
i was thinking main lighting on top and 24" tubs around the sides say half way up.

nope, that's fine, many people implement side lighting to give the lower budsites more light.

although, i should point out, the more lights you add the more heat you have to deal with. Just keep that in mind, you should be ok, but it has the potential to raise your cab temps.

I was looking over this post and if youre still paying attention to it, here's something that i noticed. You said you want to use a bunch of CFLs 65watters and u want to use 6 of them. 65 x 6 = 390 watts. The you want to add florescent tubes to the sides? Two standard 4 foot flourescent bulbs adds another 80 watts to you equation. so 390 + 160 (assuming you want to put lights on both sides) is 570 watts. So my question to you is, why not invest in a 400w or 600w HID instead... it just makes more sense, not to mention will reduce clutter and the safety hazard of plugging all your lights into the imagined power bars....
Hope this helps.

Not everyone has a situation in which they can grow using HID. Heat is a real concern for him, I believe, and without rigging up an air conditioner, there isn't enough room left temperature wise to try to accommodate the extra heat that the HID will produce.

Heating issues can be taken care of by using an air cooled reflective hood. Assuming money isn't a problem. If avoiding the cost of PURCHASING a HID is what you're trying to avoid, then of course other means are nesessary, however the amount you save in the long run might not be worth it. It will cost you only a few dollars more per month to run your 600w HID and you'll probably have better results from an HID than with a combined wattage of 570 watts of fluorescent lighting. Though that's pure speculation, and I would love to compare your setup (570 watts) with a 600 watt HPS flower setup and see how the final crops differ.
Not to mention how cluttered your space would seem with vertical fluro tubes and a host of CFLs dangling down the middle of your grow space. The image in my mind isn't pretty, but I'll be the first to admit that looks aren't everything. Function over form!
Consequently, I'm building a fluorescent flowering chamber for an experiment I wish to conduct where I'll be utilizing 4-foot fluorescent tubes to light up approximately 72 16-Oz beer cups.
If it goes well I will turn it into a tek for you all.
My thread is here if you want to check it out.
Keep up the good work though, I hope everything turns out well for you whichever path you pursue.

I agree with you that HID lighting is the way to go, running a 600 watt HPS with a cool-tube myself, but I definitely have to say that running an air-cooled reflector is not going to resolve heating issues entirely, at least in my experience. I personally think its always best to keep your light air-cooled, and it certainly has a good effect at pulling heat away from the bulb, but it really isn't going to accomplish much if the ambient temperatures are too high to begin with. Air conditioning is the only real answer if your ambient temperatures are high enough that there is no margin to allow for the heat that an air-cooled lamp will still produce.
