Diana: How large are those grow sacks in diameter? I’m using Smart Pots and they are overgrown too. I think mine (made of a black felt material) are larger in dia. than yours. I think that they are 18-20 gal. They are about the same width as they are tall. THey are also home, and I’m at work so I can’t measure them.
I was considering making extensions out of roofing material like Justadumbblonde suggested and continue filling.
Also, shen are you going to start a fall crop of lettuce? End of July? Sooner?
Those grow bags are probably 3 feet tall and 2 feet across? It’s dark out now; I’m not going out by the bats to measure them, LOL!
I will seed fall lettuces counting backwards from October 31st, depending upon what the growing length of the varieties are.
