A light question

[Torog]

Hey good luck bender, 1000watts should be more than enough. I've never used a conversion bulb, keep us posted on how it works for you.

Hey torog, What part of Texas are you from? I'm a little north up here in god's country Most hydro shops carry the conversion bulbs also.

Howdy Nosehit,

Have a good one...Torog

Torog Reviewed by Torog on 02-05-2005. A light question My grow box is 3' x 4' and I have both a 400w hps and a 1000w MH. I need to know which one would be best to use or should I use the 1000w just for the veg and the 400HPS to bud. or can I just use the 1000w from start to finish? If I get more air flow I may try to use both but that seems like a lot for a box this size. that would put me to almost 120 watts per square foot. THANKS Rating: 5

1000W agrosun. my 2 cents...

1000W agrosun. my 2 cents...

will that work in a MH ballast?

[BADANDY]

HPS 1000w work the best over all deep penatrating light bigger buds dense buds. Also good for seedlings,and veg state good vent and blower are a must

A switchable ballast is just that, you can switch from MH to HPS bulb, just flip the switch and change out the light. A HPS conversion light would go with a MH ballast, and vice versa. In the long run the switchable is more cost effective cause conversion bulbs are more expensive and don't last as long, they also aren't as efficient. But switchable ballasts are sometimes expensive.

I've seen folks use HPS for the whole grow and they look fine. They run a little cooler than MH, but in an enclosed box of that size it'll have to be air cooled and maybe you'll need 2 fans an intake and an exhaust. If it gets too hot the plants will die, try to keep it around 75-80 degrees. I'd say the 1000 is overkill, a 400 or 600 would be just right, cheaper to run, easier to cool, a 600 will be 50 watts per sq ft, which is what most reccomend. everything has to be in balance, amount of CO2 available, light, water, nutes. Just make sure you can handle the temps someway.
