Mars Hydro TSL 200 300W LED light height/intensity recomendation

I had your same problem with setting for autoflower plant, and people told me to visit mars hydro site and watch the par maps, they think we don't do it?

quantum board? 20-24" or the edges/corners will suffer. Quantum boards have a tighter spacing of diodes and need a slightly higher hanging distance than a light with strips/bars. You can download a klux app or a faux-DLI app (both measure lux/lumens and nothing else) and use that to adjust your height. Don't sacrifice overall intensity, but try your best to even out the edges and corners. you don't want less than half the intensity when comparing central areas to outer areas. I'd raise it up a couple inches if thatis the case. mars has starting lying through their teeth again on their light spec sheets (specifically the FC-series models all have trash specs now in regard to efficacy, which is what you pay for in a light). I don't have the same conifdence as others trusting them, lol. So, not so sure about their par maps anymore, but you could look at those and see which you prefer. Also, check out cocoforcannabis - they often give real world results for popular light models out there. They might have this one as it's been around for a while. they probably did all the work for you.

If you go to the Mars Hydro website, they will have a chart for your exact light with details about heights and growth stages. It is their light, they have done all of the R&D and know the best advice........consult them, they have the knowledge .............and it is far better than any "Bro Science" answers you may get from random "experts".

Mars has adviced distancies, they work great. At certain points i had only 5 cm gap, that light still did good job, but she runs hot, so good air exchange is a MUST.
