What's the proper way of introducing your babies to strong light?
week 1 I've known it as using flourescents
week 2-4 use 1-1000W hps.
week 4-8 use 2 1000w hps
week 8-end 3 1000w hps

Is there a major difference with using MH opposed to HPS?

MH is good for veg and hps is better for flower, or a mix of both for the whole process.

thanks.
how early in the veg stage should I should start using the 1-1000w hps?

I started off my clones right away with a 1000w MH with cool blue spectrum for the first 3 weeks of veg and added another 1000w HPS for the that last week. Then I kept both lights on during flowering.

Thanks.
I've heard of starting off w/ just MH then going to just HPS and then finishing the cycle w/ a 2:1 ratio HPS to MH. Due to the spectrum of the light at the beginning of fall. Do you know what the true difference in quantity is by having a MH opposed to not having one at all?
