Need help on switching out my 400w hps to 1000w

I currently have 2-400 watt hps lights and ballasts in 2 6" cool tubes. To switch it to 1000w can I just buy 2 1000w ballasts and 2 -1000w bulbs and be good. Do the new ballasts come with wiring that will go from ballast to wire into the cool tube

The size of the bulbs are way bigger. You might need a new toube.

I just realized that thanks. I wonder if the sell 1000w bulbs in different sizes

My grow room will be 6ft wide x 5.5ft long and 8 ft high I already have a setup of 2-400 watt hps lights in cool tubes will it be worth it to buy 2-1000w hps lights to replace the 2-400s

Nope!

Look for package deals on lights/ballasts/hoods/bulbs/hangers on Ebay!

Just put in 1000 watt grow bulb or kit.

2 600's might be better......2 1 K's are kinda over kill.....A 5x5 is a nice set-up for 1 - 1K...

100% agree. 2K too much and you might get heat problems, or light bleaching.

2 600's or one 1K are sufficient, and you can always suppliment w/some quality CFL's for more horsepower.

Here is what I use for supplimental CFL,s: https://www.amazon.com/gp/product/B005P29K1S/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

You can get them in both low and high Kelvin ratings. Not much heat output.

I'd go w/a 1K HID. Half the number of ballasts and bulbs to screw with.

I've got a 5 X 5.5 grow area with one 600 and about 500+ watts of these big boy CFLs. Kind of mixed and matched the CFLs with a few UV bulbs. Got 2 gooseneck lamps that hold 5 bulbs each, one of my best purchases, WalMart $23. So the goosenecks w/10 CFLs give me a lot of flexibility.

Thanks guys I'm going to go with a 1000w kit off eBay. First before I can do any of this I need to run power to by steel building in my backyard and need to figure out what amp I need
