green thunber!

+ rep

so you'll have (2) 1000 and (1) 600 watt after the purchase?

take care. im out for some venison on the grill!

Nice thread, good instructions.

I have a few questions

Is that one of those 80cfm, 4" inline fans you are using in this DIY?

Does 1 fan cool all 3 1000's?

How loud is the fan?

How far off the canopy are your lights?

Thanks, YGB

YouGrowBoyNo, that one is a 6", same type of product, higher capacity, 250cfm.

Yes.

I cant hear it. I have enough fans that are in the room and open, along with 4 ballasts, etc.

Between 1' and 2', depending on the maturity of the plants.

Your welcome. VV

50cf
ideas thanks

I think you have several things that are going to decrease the yield you will get, being in an attic is one of them. In summer the heat problems you have know will seem like child's play. Garden Knome was able to produce 8oz of bud from three known females with less watts of lights than you have, keep the numbers down, the yield will be better.
Attic spaces are hot or cold, you need to seal and insulate the space, make it like living space. With one difference, you don't want any air escaping that smells like MJ. This will require a balanced air handling system with a CanFan and carbon filter exhaust, an intake with a fan that is rated slightly smaller then the exhaust, creating a slight negative pressure. Its not the square footage its the cubic feet, length x width x hieght. Your calculations will only work if the environment is sealed. 4' floros are not an efficient form of lighting for our purpose here, concentrating a lot of light in a space. They do not produce enough lumens per watt.
I hope this answers your question, not really sure. Its not possible to have a cheap attic setup that will produce enough bud to pay for the trouble? You have to create a special environment. VV
