Box finally came in.. Added a secondary mini fan outside of the box to shoot (maybe) cooler air up into the intake fan. The space inside this box is small.. 13 inches deep and the mars hydro is way hotter than I thought it would be. Worried that the seedling only getting 7 hours of pure sun on the porch would be stressed with hitting the 18/6 schedule, but she seems to love it. Starting veg nutes next week..
if the soil is hot it means it is acidic.. ph up would be the call.. ph down adds even more acid..
so the 6.5 im adding ph down to get to is coming out as 4.5 in the runoff.. which means the water is coming out super acidic.
Can you explain a bit more about the Ph down issue? My assumption would be if the soil was hot, you would need to ph down to compensate for that. But now I see that my assumption is incorrect. 🙂 Thanks.
