These cukes get easily 4+ inches long and they are firm and tasty. As of Sept 8th, I have picked a cuke every day for a salad, for 2 weeks now.
I have not needed to replace any nutrient solution in the 10 gallon bin/tote yet. (It went in around the 3rd week ofJune, but since the early small leaves had spider mite, the newer stronger leaves didn’t take off, and make lots of flowers and large cukes, until mid August.
