Hi all. I previously have grown in dwc and coco. Right now my 2 day old seedlings are in coco in solo cups. I leave town sometimes for 3-4 days at a time. I am thinking of switching to soil to help with keeping my soil hydrated long enough during these times. Does this make sense? If so, whats a good soil? I have general hydroponics nutrients here already, and cal mag. Also, if i can buy iff amazon that would help since I am far from any hydro store. Thank you.
