You can get MH bulbs that are compatible with HPS ballasts. Saves buying 2 ballasts. But the power of bulb and ballast must match.can a 600w mh bulb or 1000w mh be used with a 1000w hps ballast?

ive just changed to 250 wats of them nlite cfls red and perple wud love to know if anyone cud fill me in on any ifo about um
That should be plenty for vegging. In fact probably overkill.I'm vegging plants under a 6 lamp T8 fixture, bulbs are 6500k. Is this enough for 8 plants? This is a soil grow btw. I just switched from MH to T8. I have tons of pics in my journal, links in my sig. Lemme know. Thanks in advance!!
I second that!Thanks for this valuable info on the lights.
I don't know anything, but I'd use 5x5 of it for a 1000w MH vegging/cloning tent, and three 1000 watt HPS lights for the rest open space. If going by the common general suggestion of 50 watts per sq ft, you'd be looking for 4,500 watts total. Likely you'd need some big powerful ventilation with cool air intake, or an AC unit though I suppose. Though just to start with I'd go for 1000 watt HPS for flowering and CFLs for vegging and work from there. Get a 30 amp line set up to a light controller with a relay for your 1000hps if you're using a 1000 watter though.Whats up ppl ... Starting my first grow soon and I'm looking to see what size and how many HPS i should put in the room ( 10' by 9' ). I want to maximize all the space, any advice i can get back ASAP would be helpful.
thanx, Letmetry
he's right he, dont know anything. 1x 1000w hps does 10x10I don't know anything, but I'd use 5x5 of it for a 1000w MH vegging/cloning tent, and three 1000 watt HPS lights for the rest open space.

That's only 10 watts per square foot. Could you link me with information suggesting that? Of the dozens of grows I've seen posted, in cases where they provided wattage and area, the lowest I'd seen were 25 watts per sq foot. Most aimed towards 30-100 watts per sq ft. The first post of this thread suggests using at least 4000 watts for a 10x10 area (4x4ft for one 1000w HPS)he's right he, dont know anything. 1x 1000w hps does 10x10
