Light spectrum?

[Shipper49]

What is best spectrum in vegetative stage? Some suggest blue is better than red- blue combo

 

[Pennywise]

Full spectrum is best for veg and flower. If you can run both blue and red together.

I use the same in VEG and flower full spectrum. Get em hot and back the off a little bit.

Seedlings need hardened off I dont do full spectrum till like 3+ sets of true leaves.
