Is it too late too add 400 hps?

2 grow, with 4-65w cfl's (2700k)
1-15w growled
2-65w (6500k)
I am growing in a small closet, but was wondering if it is too late to add a 400w hps. these pics are three weeks into flower so this wen. will be 5weeks which is when my light will be here

No way dude go for it you'll love what you get from it. just watch your heat!!! cool tubes are worth it home made ones are better do a search

Rite on, the one i bought is a switchable ballast with a cool tube.

It's never to late to add more light.

HPS is the way to go. But you NEED an air-cooled hood (preferred) or a cool tube (inferior but effective...just less effective) if you are growing in a small space.

I use a Sun System Super Sun II reflector with a 360w hps conversion bulb (operating on a 400w MH ballast) and my plants love it!

so as long as i add fans too my cool tube it would be air cooled. correct?

get at least 200 cfl unless you get a carbon scrubber then you might need highter cfm

U just lost me there sickstoner

Yes, an inline duct fan ($30 at home depot) pulls 250cfm and is sufficient to cool a 400w hps in a cool tube.
