New Setup

Sounds pretty good..Although, im not much of a grower myself..

 

ok m8 - don't want to piss on ur pizza like, but that lowbay light is 6" deep & u will need it 2ft away from ur plants - assuming ur pots will be like at least 6" tall, that leaves u a massive 1ft for growing.


plus, that is a 400w hps ffs!!! u can't use that in a tiny little box! It will cook the shit out of ur plants & probably melt the pots too!

U will need at least a 125mm rvk & equal sized inlet to vent away the heat that thing makes!

If u must grow in a small cabinet, u need to use cfl's m8 - preferrably envirolites / ecolites. But even they make heat in a confined space, so u will still need extraction.

 

sure just go down to the local computer store and buy some fans an a ac/dc adapter. or u can probally get them online cheaper im sure and i myself have found alot of ac/dc adapters sround my house off of cellphone charders etc. Whe buying a fan opt for a ball bearing one instead of the standard brushless because the ballbearing run quieter if stealth isnt an issue and your looking to save some pennies just go for the brushless. As for wiring them up its easier than you think all you need is to buy some wire nuts and expose about a quarter of an inch of the wire twist them around each other and twist on the wire nuts. if it doesnt work you have the wires backward so just switch em. there will only be two from the charger and two from the fan. oh yeah well as far as what size will depend on your grow space so i cant help ya there cus your not sure yet as i recall from your posts but neway good luck
