How come nobody sells 600w MH bulbs? Why wouldn't they make them?

Anyone have any suggestion for a good 600w bulb for mother plants?
 
There arent very many choices. But I use SolarMax. I bought them a while ago, last summer or so, when most of the bulbs were made by Ushio. But some other company took over SolarMax and they have issues now with reliability. I had 3 HPS SolarMax bulbs blow within 2 weeks. But no problems with the conversion bulb, still going strong.
I'd try and find some Ushio brand if you can.
 
600w conversion bulbs produce the same spectrum. Sunmaster makes a pretty good one. 600w for mothers is overkill though. 400w mh is fine for aggressive re-growth. T5/T8s are fine for the average grower.

A few things...I am planning on having 4 - 8 mother plants. This will be my first time cloning. I want to be able to take 60 +/- clones every 10 weeks. Is this possible with only 4 clones?

If I went with 400mh would that sufficient to sustain the growth for up to 8 mothers? 2 strains with 4 mothers each that is.
 
yeah a 400 will do just fine for mothers, plants in veg can do with much less light than budding ones
 
Does anyone know which would use LESS power:

a Sun Blaze 432W T5 fluorescent

or a

400w MH bulb on a electronic ballast
 
The 400w MH would be more efficient and the perfect choice for what you are trying to do. I am in the same boat. I need to get 60 clones every 8-10 wks from 4-6 mothers. I am using a sunleaves pioneer 4 T5 currently but only because I already have it. If I was starting from scratch I would invest in a 400w MH system.

Is there a large power consumption difference between the T5s and the 400w mh?
 
......BUMP......

Does anyone know which one uses less power?

a 400w mh on a digital ballast

or a
Sun Blaze 432W 4FT T5


THANKS!
