Just returned from holiday. Sounds interesting do you use them yourself? how do you stop the little beasties leaving the greenhouse? Had a friend and allotment neighbour tending the greenhouse. Neighbour been spraying with bug zapper while i've been away so its kept them at bay. I've been up today and took the worst affected leaves off and the fruits are fine, i picked half a carrier bag full today,next stop recipe section. Thanks for info Jim.
