Old School, homegrow, combining common sense with basic nutes available to most everyone. Using city water that tested high in iron, Ca and Si. Adjusting Ph without a meter, using drops and a color change. Centech digital laser thermometer for temps. Photo of seedling taken at day 6.
@ReinDeer, thanks! It’s a real basic grow using miracle grow and superbloom. I’m very pleased with how they vegged, now to wait and see if we get some good buds.
Makes sense that the plants should take whatever they need from the available spectrum. Since Veg turns on all the LEDs, I’ve probably been wasting my time messing with the switches, because I’m just lowering the total output for part of the day.
