Seed/nursury beds

Hi I made a nice seed bed on  my allotment as had run out of room in my greenhouse at home. sowed curly kale, savoy's primo cabbage and tons of brussels. I now have tons of each lol. had a good idea to get some funds for next yr too, I will do the same thing next yr at the allotment, the allotment assoc will buy the seeds and i will sow them, and sell on the plants cheaply to plotholders. Not everyone has a greenhouse and I noticed lots of people paying through the nose for veg plants from our local garden centre. Just thought it a good idea pass on savings, yet build up allotment funds!
