Mh question!

[jdflores07]

Hey guys! I found a cheap mh bulb online with the following characteristics and would like some input from people who have experience with mh.

220v
400w
E40 type
Mol/lcl: 292/178mm
Lumens:37,000
93Im/w
color temp: 3900


Basically i want to know how many plants this bulb could grow during veg and if the color temperature is correct to veg for 1.5 months. And also if I should add a diferent spectrum for this type of lighting.

Thanks in advance!

I believe a standard hood uses mogul e39. And no, wrong temp. You want 4K for seedlings and 6.4k for veg. 10k for last 2 weeks of bloom.

Ok awesome! Thanks for being so clear. I'll look for something in the 6.4k region.

Ideally 6400k or kelvin daytime colour light is standard for veg but more heat and fans etc. . You got 3900k how many plants will grow 60% rate. Few ounces grown good.

So something around 6.4k will be more beneficial for a more optimal grow.. Thanks man!
