i have bought some 2m sqaure gutters to use in my greenhouse.
i placed these over shelves two nex tto each other - in total i have 3 heights i.e. 6 gutters each side of the green house
what i have found is tat the radish ad some salad stuff (pak choi etc) bolted very quickly - can anyone tell me if that is beause the gutters are too shallow or if there is another reason
thanks
