vertical lighting and horizontal lighting.

you could sell your 250 and buy a 600 air cooled

or use both the 400 and 250 the big one above the smaller vertical really cant have to much light ur choice what to do

I'd do the same as dhhbomb, If you already plan on getting a 400w then you might as well keep the 250w and use both. Your plants will appreciate the extra wattage.

very well, both it is, thanks guys. do you think i should have em side by side over my grow or perhaps the 250 vertical?

Yep... exactly what I would recommend...

I use a 600 hps in a 36 x 20 x 60 home made tent...

with it all zipped up, the temps inside are around 75F...

Good ventilation is a must, but it is well worth it...

Imagine a 600 watt light 10 inches from your plants with no issues... coo tubes are the shit...

Here is a pic of my tent...

Cool, Thanks for the advice but my local headshops dont have any cool tubes in. they will order them in if i want but im looking for a solution by 8 o clock tonight. I will keep this in mind for my next grow though, Would the 250 and 400 be too much heat without a cool tube? I have got A/C and a quite large fan in my tent. Thanks.

I would say that they are too hot withou some kind of heat extraction device...

I hope I am not too late, but temporarily, you can hook up one of theose glass tubes from an old oil lamp....

the optics are not the best because of the non straight shape... but it will work until you get the cool tube...

Any bigger supermarket should carry those....

some ducting and a fan amd you are all set

hit me back....

Thanks for all the advice guys, I think ill just go ahead with the 400 for now, and get everything i need lined up for my next grow, Think ill throw a few cfl's in there too, a friend of mine has a 150 he's not using at the moment so i might see if hell part with that. Any recommendations for my next grow? I'd love to grow a purple strain or anything that not green really,, +rep.
