Dual Vs. Single spectrum?

[denialisback]

That is exactly what i am talking bout. I just wanna know if one ways better than the other.? Or if it don't make any difference?:jointsmile:

i have been repeatedly advised MH is better for VEG, HPS better for FLOWER

what does everyone else think? I'm happy with my 400W grolux though for both i guess... but gona go with a cfl veg room soon

Peace,
Denial
