How to fit a 400w and a inline fan with filter in a cupboard?

[scottyboy_09]

the optimum height for a plant under a your average hps (400W) is apparently 14 inches. I found for my plant (sativa) it kept growing even in 12/12 cycle and grew very close to the lights too quickly.

If you let your plants get too close to the light and the cupboard gets too hot they could end up with heat stress which can really stunt the growth.

 

If its just under a flood light you should be able to hammer it pretty close- I would anyway as the right one seems to be getting lots and lots of stretch.

 

My last grow went well with a cupboard that size, a 400W hps and just an old ball bearing computer fan and oscilating fan for ventilation. except for the heat stress issues- hope this helps..

Thanks again for the tip, moved the light now and looks much better.

 

Just another quick question - any tricks to stop/limit light leakage from inlet vents?

 

Cheers
