Hi Stinkbait, just starting my first grow too.. vegging under 250w right now but switching to my new 400w light this week in my new darkroom that is supposed to arrive at the hydro shop tomorrow. Hope to get plants that look as nice as yours! How are you handling the smell?

Good luck bro. I have an inline fan going from the light to a window on the side of my house. The smell wasn't too bad at all. I've begun drying some and that is startin to get a little strong but you couldn't smell it in the rest of my house if my door was closed.

Anyone using a large reflector like the magnum xxxl or big kahuna with a 400w hps? Any results to speak of with a large reflector? I have a 1000 watt in a big kahuna and I want do do the same w the 400 over an 8 site aero/Nft 3x2' SCROG

Anyone using a large reflector with a 400w? Any experienced feedback with a large air cooled unit with a 400w would be appreciated

I'm kinda in that category. I have a "Large Convertible Hood" by control wizards. It's 24"x24" but I'm running 2 - 400w CHM bulbs in it over a 4'x4' area.
If you have a good hood that disperses light well with a 1000w then it will show the same caricaturists with a 400w. If using a 400w hps ballast I'd highly recommend using CMH bulbs they are better in veg and better in flower. If you've read 1/2 the pages in this thread you've seen this link but here it is again http://advancedtechlighting.com/cdmed18.htm with this bulb you can leave it open no venting (heat is much lower) My bulbs are less than 12" from the canopy with no heat stress.
I'm sure a single 400 will run a 3x2 screen, your hood shape and light dispersion pattern will make the most difference in a rectangular pattern of your space

Hello fellow 400w users, Good to see we got our own thread. I a growing 4 purple kush plants under one 400w hps bulb. I vegged under cfl's for 6 weeks, then moved under 400w hps and switched to 12/12. I dont have a carbon filter at the moment, but that is my next project. Not sure if i wanna make one or buy one. Either way i want to buy an inline fan and i figure i might as well get the combo deal. Feel free to criticize.

I'm running a blockbuster with a 400 and its working real nice. I wish I could run a 1000 in it, but thats just not possible at the moment. Heres some jackberry and cosmic brain at 3 weeks under the blockbuster

Nice grow yourself. I wouldnt mind growing under 1000 either but its just to hot in such a small area. I like the 400. Its not to hot but still can grow some good bud under it. Just walked outside and things are starting to get a bit stinky. Hehe im not running a carbon filter atm

Yea I am currently using a 400w digital hps/mh with a large reflector that Im pretty sure is a 2.5x2.5 and it works wonders on the area I am using.....my grow area is only around 5x5 and it works great and it def shows more production than using a regular reflector, Nothing crazy but u can def tell a difference.
