Mephisto Genetics Anyone grow mephisto with cxb3590s?

I don't meassure distance.
Buy some cheap LUX meter if you don't have money for PAR meter. Because distance is not usable data, everyone have different tent (reflectivity) and amperage etc...
 
You plants can take more light in flower than in veg. I ran my QB light at 30" in veg while running at 360 watts. A meter will gauge how much light is hitting the canopy but that doesn't tell you where to put the light. And every strain is different. Watch closely for light burn, it starts at the tips of the top leaves. You se the slightest sign, raise your light 4-6" and see if it stops. If your light is as high as it can go, time to bend, tie, break branches!
 
Yea I started on hps until about 4 weeks then added one bar at 170w to 400w hps and was fine but now it's all cobs they are abit shocked I think lol.
They are at 42 days and 30 I think. Overnight the leafs went from fully spikey to softened and praying so see how they are when I get home, they are still getting on really well.

Veg 300-500 umoles, flower withour CO2 up to 1000 umoles.
With cheap 10$ LUX meter you can get pretty close with these numbers as with 150$ PAR meter. We know QER, LER and other numbers from calculations and also from sphere tests.
