Light Calculator 400w HPS

[The Stoned Jester]

Can someone point me in the direction of the light grow room calculator .. I remember there was one on the site at some point, but be blowed if i can find it anywhere.

 

I want to know if a 400w HPS will be too much for a 90x50x160cm tent, I'll probably need a cooltube as well.

I've got that set up for youngsters and works great. Sometimes ill use a globe thats done a cpl runs so it's not as intense. I don't have a cool tube, just a decent 6" intake/exhaust and temps are perfect.

 

Good luck man let us know how you go

Buggered if I can find it these days, TSJ. But I think merl1n found it for someone a month or so back.

 

From memory, what you mentioned there is above optimum. And I'd say the cooltube would be a must, unless the ventilation is on the extreme side as well.
