Get a tuning fork of middle c. Ring the fork and place the base against the base of the TOMATO flower. Pollination will occur.
This mimics what bumblebees do naturally(the buzz is what causes the pollination). This technique has been used in (small) greenhouses for a very, very long time. Large greenhouses use other methods as it is too time consuming to 'ring' every single flower.
Pollinating peppers is a bit harder.
ed: I say that because they are S2B self pollinating but if they are not doing it, I don't know what key will stimulate it to occur. ...have not tried middle c, maybe you can?
Loud (to the plant) classical music might work. I had a friend years ago that had amazing plants all over the place and claimed it was the (classical) music. I read some research reports indicating positive reactions by various kinds of plants but, honestly, I don't know.
The "snobs" probably won't be bothered by classics. They might even start being nice to you.
One more thing:
If you are feeding the plants with a (relatively) high nitrogen content fertilizer, stop. Too much nitro' will cause both peppers and tomatoes to grow but not set fruit.
Depending on the size of the container, try a pinch or two of EPSOM SALTS( Mg sulfate ) instead. Grocery store, drug store, ... carry Epsom Salts. The tomato will appreciate Epsom Plus(Mg + potash) but that is probably going to have to be obtained from a garden center(or internet).
Just a pinch tho' cuz too much won't make it work any faster|better and can burn the roots(plants die from that).
(pinch == 1/8 - 1/4 tsp out spread around the edge of the plants' "drip line" & water it in afterwards).
Good Luck!
