Interestingly enough, no one has an idea? Okay.
I planted strawberries and a melon yesterday. For planning purposes, two three-gallon pouches fit in a 1020 tray.
I put the melon in a 15-gallon pouch. That's a much larger pouch than the grow-guide suggests, but I'm curious, at the end of the season, to see what the root structure looks like. The grow-guide suggests 5 to 7 gallons for watermelon and pumpkin. I assume honeydew would be similar?
I still have peppers, basil, and more tomatoes to put in pouches.
