Indoor Need Some Suggestions On This New Cab

[Monkeypox]

15x32 ....... a 250HPS would cover that nicely . 400 might be a bit overboard . You have 3.3 cubic feet of space . A 250 would provide 75 watts per square foot . Recommended is 50 watts per square foot or 5-6000 lumens ( a 250 would be around 8000 lumens per square foot ). That being said , if you run a dimmable ballast you can run a 400 on 50% or 75% and if you increase your grow space you will already have a larger light by simply running at 100% .

Exhaust ............ Best is to have inlet at the bottom to draw cool air in , preferably on the opposite side that your exhaust fan in on . Creates a nice cross breeze of cooler air across the plants . For an 18x28 cab with a 150hps and 100 watt led i am only using a $13 bathroom fan ducted out the top side with passive air intake on the opposite bottom . The temps stay 2-3 degrees above outside room temp .

One trick if your plants get close to the light is to hang a sheet of glass just below the light . It allows air to still circulate by the bulb , but gives a barrier between the light and the plants . Of course if you run a cooltube the above is moot .

Thanks Plur, do you have a cool tube hood, Mines not a cool tube, Im having problems with heat in a 3x3x6ft high cab I built with the 400 in it and I got 2 exhaust one for intake and 2 circulating, temps are still 90. And why wouldnt 6 be good if the right light is given to them, I just dont understand, I see guys with 4 in pc cabs, is it the light or the room. And being Im just learning I know nothing about scrog or LST, wish I did

What size is your exhaust fans?? It sounds Like you need more exhaust. If you have good exhaust, and good passive intake, you do not need a fan to pull air into your grow box. Also your exhaust should be near the top of your grow box, and the intake should be at the bottom. Maybe you should move your intake fan, and change it to another exhaust fan. Then make sure you have enough of an area of intake, so that it allows your exhaust fans to pull at max efficiency.

Have a great day

P.S. You have 54cuft of growspace. You should have at least a 54cfm exhaust fan, to completely exchange the air from your grow box, once every minute.

So I guess I'll do either 3-4 and see if I can get away with that, Im building the current light pictured below, 12 cfls and Im doing everyother bulb flower and veg so I have 50 50 of the 2 spectrums

Nice light fixture....But if you don't mind, let me give you some advice with auto's and cfl vs hid grows.
First off, I grow with T5 HO flour. 8 bulb fixture and 432 watts. I've grown with only veg. spectrum, only bloom spectrum and a combo every other bulb mix.
That being said, the best grows I do are with the veg. lighting all the way though on 20/4 lighting.
OK, this don't do so well with HID. Spectrum wise I mean. HID gives you the best penetration and switching or just plain starting out with bloom spectrum, start to finish works the best...Ask other HID growers. And also ask other cfl growers...

So, like I said, in my opinion, with the cfl's, go all veg. spectrum

No mines just under a standard reflector but a cool tube would work well, my cupboard is even smaller 2ftx2ft corner cupboard. It is possible, I have my exhaust fan directly above light, it empties cupboard 10 times per min, and uses very little power.

6 could be fine, like I say its alot to do with strain, pot size, method of growth.. U could grow a photo and do 12 cuttings.. Its all something to consider before buyin or planting seeds. I made the mistake of growing a maxi gom, I only wanted a little auto and ended up with a bush..
you would manage 4-6 smaller type autos, but if u get a larger strain, larger pots, soil mixes.. You would only be able to fit 2 in your cupboard and need hps..

Hope im helping a bit..

Thanks Rip! I'll grab a few extra veg bulbs today, And Plur Im gonna attempt to hook the HPS up in there and see what temps are, if they are too high Im goin with the new DIY CFL hood. I guess I'll try 3 or 4 and see how it goes, What size square pots should I go with with the measurments I posted of the dresser?

 

[p.l.u.r]

Definitely start with your cfls,

They will provide a much better light for starting your plants off.. Hps is good once established, I never start with hps.. Im Not to good with pot sizes, I never had the space issue before, I use to grow photo's so I just use to get the biggest I could get and now im in hydro..
Why strain are you thinking of growing??
