400w HPS Canopy Penetration?
Hey guys, I'm wondering how many inches deep a 400w HPS will penetrate past the upper canopy. I'll probably have a 2'x4' ScrOG setup going under an HTGSupply 400w HPS system. Thanks in advance!

For a HPS 400-430w I'd say 2-3 feet, 4 at max anything below 3 1/2 seems to die off or go yellow

...400 will only penetrate your canopy approx. 12 inches in a scrog, to be optimal.

i got a 600w hps 10 inch over canopy and every think under 3ft goes yellow.
but if u can open up the center of the plant it will penetrate more
but cut off all th lil branches at the bottom coz it wont produce much anyway look up lollypoping.
and open the centre hope this helps
