Not really, all flowers have pollen. Pollen does differ between plants though, thats why some people only get hayfever from grass, you'd just have to try things out because it pretty much depends on the person...my daughter gets hayfever in the autumn because of fungal spores and things like that, but not so much in the summer because of the grass pollen etc.

use clear silicon, from a tube. put a thin layer in the frame, let it go off for a day and then place the glass in with the clips. The clip will force the glass down against the silicon forming a seal. Works nicely for my greenhouse.

yes, you can eat them as greens i think, like spinach but not as tasty.

It sounds like they might be too dry, If they are in pots as opposed to Growbags, you need to water them every day - do not let them dry out and feed them with tomerite (tomato food) every two or three days once you have tomatoes formed. Another thing is that tomatoes like a humid atmosphere, and good ventilation, which may be harder to achieve in a conservatory, Goodluck.
