dual core bulbs??!??!

[FuZZyBUDz]

i was browsing throo a catalog fer gardening and seen dual core bulbs...1000 watt hps/mh bulbs....r they good? that sounds all fukd up to me seems like 1 would get hotter than the other (mh), but i was thinkin of gettin 1 with a water cooled...hood i guess it would b called, but yea i wanna kno wat sum peeps think first...lemme kno?

They are kind of cool as far as the spectrum but no where near the lumens of a strait hps.

it said roughly 117000 lumens, but im in a closet here...so isnt that PlEnTy?? 24'' {wall 2 doors, 6 feet wall 2 wall, 9 feet high, with a shelf at the top.} should i just go witt like a 400 hps and mayb a 250 mh??? for veg and final weeks of flowering. im getin a window ac fer da closet too.

i didnt need to qoute that...at all.

Very true, enhanced spectrum, lower lumens but the same amount of heat.

Sunmaster dual is about 100 lumens / W.
Hortilux dual is about 110 lumens / W.
Compare this to a straight HPS : Phillips,solarmax ~ 145 lumens / W. or a straight MH at about 110 lumens / W.
So both the MH and Dual bulbs are 3/4 of the light output of a HPS for a 1000W bulb. So I'm sure a lot of energy is lost as heat, but the total heat will be the same. As far as your ac, for a 1000 W bulb, 3500 BTUs is your absolute minimum, but I would go with twice that just to be safe.
My conclusion would be that this would only be a viable replacement of a MH during veg. ( downside being extra cost at an unknown benefit ) My experience has shown that total light is more important than spectrum during flowering, so I would always use a straight HPS for flowering.

This is a good thread :

Assuming that you want only one grow space for all phases, I might go with a single 600w HPS digital/dimmable for all phases with CFLs for the smallest plants. <- notice my bias towards my current setup..

i am using the dual arc hortilux on my second grow ,and it seems to me that the buds are fatter than the first grow i did with the 1000 watt hps ,,think i will continue to use it on my next grow

yeah i need to pick up one of the dual arch hortilux bulbs. the added blue is sopose to help the trich production durring flowering.

hahahaa dope dood!! love the input yo! i really want a lil mh cuz throwin a mh an it in the 2nd to last week of flowerin to add resin, and fer veg too, i dont like the cfl's tho, i use em now and i got a 150 watt hps but NEED to upgrade asap

yea it kills the plant xtremely slowly and then bulds resin (tryks) to protect itself! that y im tryin to get 1 and oh yea a water cooled tube, r those efficeint i kno ill need a chiller
