Irish., excuse me? You mean my plants look good because of the DM, and not OC+?
...ya know I was following Setting Sun's LED Hempy grow
In the temps you're describing I don't think there should be much difference between the OC+ and the DM. Those are optimal temps.
I don't understand why you guys feel the need to mix them. I've got 3 grows with OC+ and have not had anything but great results, especially on the most recent one.
Why mix? The OC+ has the better micronute profile by far. As long as the temps are in spec, I think it's the best choice for hempy. In soil, I don't see how it would matter much.....either OC or DM would work fine.
