My Fisrt post!

And a question for those with some experience with 400 watters or a growing einstine might due.

I have a 400hps with a 500 cfm blower. I want to keep the box as small as possible, while obviously keeping optimal temps. Any ideas???? Equations?? Anything??????????

Other factors are involved such as abient temps, are you suing a carbon scrubber, are you willling to used a cooled hood/cooltube? Do you want the blower/filter on the inside of the box? What medium (ex. dir, hydro, aero)? Do you mind continually monitoring and training and maybe destroying a few grows before you get it right?

I would say smaller than you want to go. In other words, you can go smaller than would allow you adequate space for the res and plant height.

Makeing some broad assumptions I would say 2wx2Lx4H. But be mindul that this would give a you aplant height of about 2 feet max...

I am by no means an expert but i would say 2x2x4.

I always think you should design around the growspace as opposed to components...

Anything smaller than a 3 x 3 is going to be a waste of light.

so user friendly..in my cab i am using a 600 in 3x2. Is it a waste of light? I was under the mpression that the more lumens the better.

I know 400 covers 3x 3 but couldnt you get more lumens per sq foot in a samller space...without it being a "waste"?

I am rather new myself..please advise..

TY

If you don't mind small plants, the smaller the better. The smaller your room is, the cooler and dryer it will run. Just pick a max height of plant and add at least a 12-14" for space between the bulb and the plants (hopefully it will run cool and you won't need that much). Add any height for pots and the height of the reflector you're using. Try and evacuate the air parallel to the bulb (have the exhaust of the room inline with the bulb).

It's really hard to predict when a plant will stop growing tho, so good luck. Try and use clones.

You'll get dense bud, but to take advantage of the extra watts, you'd need higher plant numbers or more square feet of canopy.

Btw, you're not wasting any light by going small if the walls of the cabinet are lined with reflective material.

Not true........................

explain a little of this to me please?

the only way I see that he could be "wasting light" by going with a smaller cab is that he couldent fit as many plants in there or keep the canopy as big.
I was thinking you should make it 3x3x3 that way you get as much plant space as you can from the light, and a 3ft height limit on the plants.
then maybe find somewhere for a mother plant so you can keep a sog in there....

Denser buds do not equate to a "waste" for me... Thanks for confirming Hash...
