Had a bit of a look at Mattybears grows. The led’s i used were Fluence, Valoya, and 3 different ones from Alibarba china. I tested these against Hortilux 600s, Indoor Sun 600s and a some 600s from China which I had left over from another order. I also did a mix ratio of 1 led fixture = 1200 watts conbined with 1 Hortilux which also almost gave 1gm per watt.
Heat factory wasn’t that much difference as the drivers for the LEDs if attached and inside the tent were similar to HPS bulbs. The LED light gave very little heat, but the drivers did. Solution to this is have your drivers on extentions outside the tent.
Because the new room hasa 6 to 7m high ceiling i don’t see using either will produce a heat problem.
The cost of fitting out 1sq/m or 4x4 using led fixture is around $500 USD atleast. Remember I have 160sq/m = around 80k. From my calculation and they could be wrong hence the reason I’m asking here for idea’s to do the some with HPS 600 the cost is for 160 hps lights is about 25k USD.
Power usesage was not that significant to offset the cost of the LED, in fact, the pay back ratio rate of return in electricy for the leds was around 10yrs, so not really that viable at this point.
Where are a new company here in New Zealand and its important to keep our costs down while delervering a superior product. So far the HPS system looks best.
Back to my original question does any one have a lighting plan for 160sq.m? Either using HPS 600/1000 or CMH 315 or 615s?
Perhaps the moderator could contact Robert and ask his opinion?
