Hi SPARE and @stoneotter, I think @flashmp3 using two of the TSL 2000 in his grow space, 4x4. The total wattage is 600w.u know how much par u get out of it, b4 bleach?
As for the par data that will bleach the plants, we didn't have data for that, but I have data that how to grow the plants great:
- Veg: from ppfd 200, plants will grow, but they will great exellent if reaches around 600~700
- Flower: from ppfd 500, they will flower, and if the data reaches 800 ~ 1000, they will flower great! And the ppfd 1000 with 2000 or 1500 differs very little, so too high ppfd is no need.
Hope this helps.
