jewels Posted June 7, 2011 Report Share Posted June 7, 2011 Quite a broadrange of lighting there. If my math is correct - and it seldom is , , , The values in table one illustrate light @ 23, 90, and 253 Table one shows greatest growth @ over 250 ( extrapolated ) PAR. Thats a pile of light - even for me. Can we apply the same (LUX) values to figure #3 ? Quote Link to comment Share on other sites More sharing options...

ubr0ke Posted June 8, 2011 Author Report Share Posted June 8, 2011 According to apogee your math is slightly off but close..high light having a par of around 205. Thats 2 t5ho bulbs with individual reflectors approx. 16" from the substrate. I think its safe to say the lux values can be used with figure 3.
