DLI for 2X4 tent of mixed autos?

Seriously, go to 18/6, cannabis NEEDS sleep! Without sleep plants can not complete their photosynthesis cycle and can not have a correctly functioning metabolism either. Without a correctly functioning metabolism, your plants can not make proper cannabinoids. Plain and simple! 24/0 could only be recommended by someone who does not understand photosynthesis or how plants function (or perhaps both principles?).

I highly recommend running anything but 24/0. You understand the concept of DLI, so just adjust your umols/sec to get your specific DLI with a break for your plants. If your shooting for 40 DLI, then you can get it with 18/6 or 20/4 by getting the correct umols/sec to your canopy.. Give your plants a break. If you can achieve the same DLI with a break, why run 24/0? Hope that made sense

40-60 DLI is optimal in late flower so about that stage i will try 25-35 dli and see how they react. AF and photos takes same amount dli but you need less light with 24/0 than 12/12 because potential dli reached easier. 21 celcius not too low but i would try it up little bit. Plants look good 😊
