400 watt HPS for cab?

[Jiu-Jitsu Bluey]

Thx Tokudai for answering my ???'s and I appreciate your opinion on the light and venting. The only reason I'd like to go with the 400 is this cab will be just for flowering when I get a couple harvests in. Then I'll make/get another one for the vegg/clones/mother. Saves me a future upgrade.


What would you recommend for exhaust? The Vortex 6" 449 cfm or a Dayton 465 cfm? I will also be putting in atleast 1 other axial fan at the top of cab. I can put it by a window to pull air from outside or I can vent it outside. Dont think I'll be able to do both that way tho.
The cab is located in my garadge and I only need minimal stealth as I dont want it to be obvious whats going on other than that its a go.

O and a correction it's not 3' but just a little over 2'.

what is the size of the flowering area if its about 2 by 2 a 400 will be hard to do and a 250 would be a better choice if you had the whole cab to use for flowering then a 400 would be your better option.

[Jiu-Jitsu Bluey]

well the flower area right now will be about 4' width x 2' depth x either 6' height or 4 ' depending on how I section it off. Maybe I can call and try to get the 250w before they ship it just dont want to wish I had got the 400w when I use the whole cab.

a 400 is about the perfect size for a 4 by 2 area and would use the 400.

You will wish you would have picked up the 400W, IMO. I have a cab that is a little under 4x4 that I had a 1000W MH for veg and HPS for flower in with an air cooled hood and a 172 CFM 4 in vortex pulling air out into an air scrubber with a couple little fart fans for intake and it was cool. I now use the cab for veg with a 400W and it is always cool and I don't need the fart fans, but the air cooled hood can make all the difference. I could of layed the hood on my tummy even when I had the 1K Hortilux in there.
Also, I have a row of 5 CFL lights up top with a small shelf about 8x20for a clone tray that takes up very little room and gives out very little heat. I can put a 10x 20 cloning tray up there with 18 clones in it and it works fine.

PS, I have a thread somewhere around here with pics of it.

Here is a thread with pics of the cab when it had the 1K.

Hey, I am thinking about putting a 250w HID into a grow cab where ventilation may be an issue. The cab will only be big enough for 4-6 plants. Is this going to cook my plants or is it a low enough wattage? I might be able to get my hands on a 150 watt HID. Should I use that instead?

any light will cook your plants if you dont have the right ventilation.......weather it be 250hps, 150 hps or some clfs. cool air in, hot air out.
