Hey,
Long time lurker, first post but I've decided to get involved in the LED revolution, problem is I have a slight case of dyscalculia made even worse with you guys swapping between metric and imperial
.
I saw the setup below in the thread and a further comment by supra that high PPFD could have negative on potency/flavor as well as diminishing returns, so have been trying to work out what the PPFD would be for a canopy space of either 60CM X 60CM or 75CM X 75 CM using the setup below, but converting into lux, then PAR and then umols etc just scrambles and switches my brain off
.
The reason I have gone for 4 is to allow uniformity of light, by splitting the grow space into quadrants, although willing to take suggestions for ways to maximize this space?
