I have a hydro greenhouse where i grow tomatoes cukes peppers lettuce etc... first of all the flowers can fall for more than one reason, and ime, they can tolerate much more heat than mj. one sure occurrence where flowers fall off is the excess of nitrogen, tomato plants should not be dark green to flower nicely, and i have seen them loose almost all their flowers because of that, and ended up with a jungle of leaves. in fact it was very cold too, so maybe cold temps also contributed. otherwise, tomato plants will overgrow your weed and it's a bad idea to plant them indoor near mj. most varieties that are in market don't need any bees. cukes need bees.
