600 watts in a c-24?

[Sneaky Ninja]

[I just edited my last post some so you might want to re-read that to catch what I added in.]


Not sure of size of the tub, but I'll be cutting holes in the floor. So the tubs are sitting on my floor that will save me 3-4 inches tho. the holes will be at least light tight, around the tubs.

(good size for 400W bulbs btw)?

Not sure what you ment by that.

 

[mace_ecam]

res size is dependant on light size, the more light, the bigger the res
a bigger res keeps things more stable, EC, pH, temps, DO, etc...
a good rule of thumb would be 2 gallons per 50W of lights, that would be around 16gallon for 400W, 20 gallons is better

i recommend to calculate the heigth of all involved parts (cooltube, plants distance from cooltube, heigth of tub) and then see how big your plants could max get, 2' isn't unusal at the end of flower if you try to keep em small

i guess you should be fine, but do the maths to avoid unpleasent surprises down the road

Alright all of that wouldn't of crossed my mind. Makes alot of sense tho. Thanks for all the help. Deffinatly helped on more than I ever could of imagined from this one thread.

Also should I have the air being sucked through the cooltube coming straight from outside the cab? Then have the cab vented seperate? I mean to help keep temps down a bit more? I'm thinking not.

Or should I go pretty much with what I have drawn up in my first post (well something similar?). Any suggestions on making it a bit better of a design? Should intake be kind of symetrical in the cab? I'll have a fan or two circulating inside so that might change the answer.

The setup in your drawing is the right one - you don't need 2 fans (and the light on a separate cooling loop) unless you run C02 (which you won't). Rather than making a cooltube I would suggest that you purchase one (or purchase a hood with air cool fittings and glass). A 4" or 6" Vortex powerfan will suit your application.

One other thing to think about - you will be quit limited in height. You might want to think about throwing some of that stuff (like the fan and the filter) outside of the box. A hanging hood takes up a foot - and you will need another foot to make sure you light speads enough to cover the plants. Your pots (or res) are also going to take up a foot.

The space issue is why I was thinking cooltube over the reflector. It just looks like it would require a little bit less room. I could definatly take out the shelf, and throw the things in a small fabbed up box on top of the cab tho.

How do people in C-24's do a grow like this, while keeping the top shelf tho? I mean it sounds like I'm going to have a problem with it. Should I just go scrog? or Sog? Just train them to be short? Will that affect yeild much? I'm willing to work with the system to get the most out of it.

If you use 1' pot (or res), need a 1' for the fan (mounted in the shelf), another foot to hang the light, and another foot between the lights and the plants you have already used 4' of you space (without including a carbon filter in the box design). This would mean that you would have less than 2' for plants. You can grow nice plants less than 2', but not without flowering early (like from small clones) or training (LST or Scrog). The height restrictions migh rule out some of more stretchy strains as well.

400hps
don't forget that what ever youre outside temps are will reflect on the temps in youre grow cab. example: i have mine in the garage, my summer temps are in the 100's so my cab is to hot to grow in. right now my outside temps are in the 80's and my cab temps are 1 degree above ambient room temps. i vent my light seperatly from my cab for my winter grows. hopes this helps in some way,,,,,,,,dwtc

c24 with 600watt hps temps are 2* above an ambient temp of 73* during middle of summer.I cool the room with a 6500btu ac

Thats awsome to here. How do you have your intake/exhaust system setup? I would love to check out more pics of your cab/grow if you have them. Also what kind of yeild are you looking at in there?


Thanks for all the help so far. This thread has already helped me out so much more than I ever would of thought. Alot of small facts I would of never learned or would have overlooked if I didn't start it =].

 

[wickedpete66]

If you looka the pic with hood . you can see the ducting going from the hood to my vortex fan. I sat the vortex on top of cab and traced around the intake ,cut it and it just sits there.the rest of the fan sits on top of cab ( stealth isnt a big issue for me).

My friend has a situation like yours, a C24 right next to an AC. Not sure on the btu's, but it's probably around 10k. He runs 2x 400w in there and manages to keep the temps in the low to mid 80s. Personally 800w is too much but a 600w is very doable. The cab best fits a 400w or 600w.

And having 2 lights is always better than one because of shadowing. However 2x 300w vs. 600w, the 2 lights will be less efficient (less light) and produce more heat for the same amount of power.

Haha I love hearing about how this has worked for other people. Searching here it seemed like everyone went 400w max, and I wanted just a tad bit more than that. (I've always been the person to go all or nothing, not a good way to be) =\. If you could find out how he has his ventilation setup I would apreciate it a whole hell of a lot.

Thanks for the input? lol

He just has a Dayton 465 on (fullspeed) whenever the lights are on. One of the lights is an air cooled hood with ballast enclosed and glass on with ducting cooling it. The other is a remote ballast and the hood has no glass or ducting running to it. He cut a few small holes in the back for intakes. He was just running a 400w until recently when he put the 2nd one in there. In the hottest days of summer I think it would be too hot, but temps have cooled a little here over the past month. In winter with a window open it would be much easier.
