Help me calculate my PPFD

0mfg420 · Jan 6, 2017

Hi folks,

Can you folks help me calculate my PPFD?

4 x Cree CXB3590 3500k CD bin with meanwell HGL-185H-C1400B driver.
And i'm using 60degree glass lenses. And for grow space i have 2' x 2' tent.

On the last pic fixture is 45cm/1,5' from the wall and the light hotspot is around 2' or 60cm in diameter..

Okay, when i build this light i calculated it to be around 800 something, but i guess i had bad formula..

with 1200 PPFD should i worry about bleaching?

Nice light & keep light 2-3ft above canopy for veg(500-800ppfd),
1-2ft flowering(800-1200ppfd).
:peace:

Yeah, this will be my first indoor grow... I've been growing outdoors for three or four years... So i'm not expecting much of my first 3 grows, just to get familiar with strains n' try to dial everything in...
