More light?

[Xaliuz]

I know i have seen a thread here somewhere on the subject but didn't manage to find it.
On monday i will have a extra 600w ballast and im wondering if it would be overkill to use both? Allready running 600w HPS and 2x250w CFL over 3x4ft of plants. Using aprox 60% of the tent so i guess the plants could be spread out a bit more. What do you guys think? Have a backup ballast or go all in?

If you have the ability to handle the added heat AND the plants will tolerate it, then proceed. I suppose the only accurate way to determine if you have enough light energy is to get a PAR meter-then you can make direct measurements.

Ideal light is 10,000lumens per sqf anything over that will definitly need extra co2. Asumeing heat and rh is under controll.

I'm curently looking for info on optium co2 levels on lumens so when I find out more I will let u know. Also co2 os only used when lights are on

I hav always be leave in a back up everything how easy is it to get and how long? Other than a heat prob. I would go for it,since u have enough to keep them alive if one dies. Luck to u

Thanks for chipping in, fellow growers in spirit Placing a order now for another bulb asap. In that case the plan will be to gradualy lower the lights so the plants can adjust. Went overkill with the exhaust so the heat shouldn't be a issue, yea well, time will show.
