I just ordered 4 150W 16000 Lumen bulbs http://1000bulbs.com/product/4977/LU0150-0007.html

Now I'm no electrician, and I have no clue how to wire these appropriately in my grow space. Will I need a ballast? I've been searching literally everywhere for E39 plugin sockets or really ANY E39 sockets that are compatible with this bulb. Did I do something wrong? Are these bulbs not adequate? Maybe http://www.lectrons.com/product/e39-enclosed-rated-mogul-104.cfm ?

Exhaust and ventilation I hope to be able to use two 44.7 CFM computer fans wired to AC adapters for power running 24/7, one for the intake which will be located probably on the lower right hand side and one for the exhaust, mounted on the top left back corner connected to a carbon scrubbed on the outside. I'm not sure about most efficient CFM usage but I will be having the fan push air into the carbon filter. I will cut a hole the proper size for the lip of my carbon filter to not be able to pass through, and I will then mount it by installing my fan and screwing it into the wall anchoring the carbon filter and hopefully creating a near airtight seal.

See the thread mentioned above if you want view some pictures of the growing space! It's only about 11.5 cubic feet, so 44.7 CFM is an optimum CFM for me. Is my method of mounting flawed? Is there a better way? Do I NEED to have ducting?

That's one reson why you don't see people running multiple 150watt bulbs.

What would you then suggest for the best costs for an 11.5 cubic foot space? Would my plants still thrive with only one 400 watt? If that is the case, then I suppose I can put one in each section of my cabinet, but I'm a little worried I'll be short a few lumens of my maximum potential.
 
Although I guess with a 400W bulb I couldn't have the plants very close meaning I won't have much space to grow in at all. So with that being said - would CFL's be cheaper and a better use of my space?
 
Designed a light rack that will be hung by two or four anchors held tied off with 125lb rope. The light rack should be able to hold 12-16 23 Watt 1600 lumen CFL bulbs, and will be easily adjustable. Threw it together with two scrap pieces of wood from the cabinet, and two metal bars with screw holes in them I conveniently discovered as I was taking a part a light fixture. Still not sure how I'll wire the lights, I suppose the easiest would be to wrap all the cables together and just run them to a surge protector or two. The frame is about 15.5" wide, and about 3' in length. I'm unsure of how I plan to fasten the light sockets to the wood. Any ideas?

All this money you are spending on bulbs, fixtures, etc... Couldn't you just buy a new 600w hps instead that comes with a reflector and cool tube? Just sounds a lot easier and manageable than all this... And you wouldn't have to wire anything either... Just plug in. Also light would be much more powerful than cfl's or 4 150w hps'. 600w is apparently the most efficient size.

Not for my sized space. A 600 W HPS would not only force me to keep greatest distance between the plants and the lights (What is is 1-2 feet?) Which if you actually read my post I don't have the space. Not to mention the amount of heat in general it would put off. Again, my cabinet is 11.5' cubed, which is why I'm opting for CFL's. Plus I'm getting 12 2700K 23w 1600 lumen bulbs and 12 65000k 23w 1600 lumen bulbs for $70, along with my 12 corded sockets will only be around $80. 600W may be the most efficient, and one of the most popular, but not for all spaces.
 
Besides, this adjustable light rack I made will be super easy once it's complete and it provides even lighting throughout. I may add some more lights on the side if I see fit. Are using BOTH 6500k and 2700k bulbs together effective?
 
Well the light rack proved to be more trouble than it was worth (at least for me) I'm just STUCK here thinking of an easy adjustable way to hang my lights preferably sideways preferably 12+ of them. I don't exactly know all of my knots so that may be my problem lol. I just haven't been able to come up with a easy to manage system yet for this grow space. Anyone help?
 
Hey there Stevegrows, got a read through your post, been offline gardening for too long returning to the forum now. Need a bit of info on your space to give you a better idea of steps ... My math skills depend on day, but I approximate your space at 2`x 2` x`6` ... Keep in mind that you`ll need to exhaust your ENTIRE volume of air in about 3-5 minutes so judge your fans accordingly in terms of CFM.

With lights, basic rule of thumb for indoor is 50w of HPS light per sq/ft (floorspace) or with CFL`s, judge by 2000 lumens / sqft as a base. Now with that said, it WON`T give you maximum penetration with CFL`s, I HIGHLY recommend doing HPS for at least the flower. I`ve personally had good success either way, but HPS offers maximum growth potential. Also, 400w HPS would be fine for your space (given my estemations are right) and you can keep it right about 6 inches away with an cooled hooed. As previously mentioned, will be A LOT easier, and mor efficient in the long run.

Happy gardening, feel free to inquire further :)

I must have missed the "I'm growing in a cabinet" part lol. CFL's all the way bro. Make sure to pick up some zip-ties for all those cords too! Good work on the rack. I would set some side mounted in the cabinet too so all light isn't coming from above the plants. Should help get buds on those lower areas during flower.
 
you could also use T5 fluorescents I've seen some pretty good results with them some people use them for veg and flowering I'm sure you could find someone on here that uses them that could help you out

Yeah! I plan on doing that actually, as I'll have 16 2700k bulbs and 12 6500k bulbs. What I finally decided one was that I'm just going to drill holes in the side and hopefully I can find some metal pegs to insert in them. This way, I can easily move my light in 1 1/2" increments. I just need to find some dowels or something that I can fit in the holes so that I can mount it. I may actually just use some long screws, that might be the easiest way.

Space is 32"x16"x28" so 44 CFM should be plenty. Right now I'm pretty much just waiting for things to arrive, and I need to head over to home depot to buy some more light sockets.

Does anyone know if it's safe to secure light sockets with a zip tie? I don't see why it wouldn't, and it would sure be the easiest way!
 
Don't think cfl's can get hot enough to melt zip ties (not mine anyway). Good idea with the incremented holes btw

Thanks! There was actually a few holes pre already placed which is how I got the idea, I just need to order some steels dowel 1/4" diameter 2.5" long and it will literally be a PERFECT fit. The space is 36 inches long, the rack is 31.5 inches. Could not be any happier with that decision. I think what I may do is only buy 10 of them, as they're kind of expensive. You can find some here btw if anyone is interested. I'll just use 8 of them so that I can easily move the rack up one peg, and move the ones below up. I think that will be the most simple and cheapest and effective way possible. I'm just waiting on things to ship and I need to wire my lights, I can't wait!
 
So I'd definitely like to use BOTH my spaces, but I can't afford buying another 24 lights. Is using a combination of both 2700k and 6500k effective? If yes, then woohoo! Having 6 plants would be amazing! Does anyone see any problems with this? If not - awesome!
 
Good looks on the dowel pins. I needed some to fix a bookcase lol. If I were you I would definitely use both 27 and 65. I don't remember the exact light absorbtion (that even a word? lol) but both of those spectrums are close to the best spectrums for canni to grow.
