Dear Tika- Of all the seeds you could try this with, beans are probably the best as they are very fast growing. Once you have planted them they need a few days to soak up water and get ready to start growing. After perhaps four to five days you should get the first root coming out of the seed, with the first shoot coming out a few days later. Within two weeks you should have a baby bean plant, complete with leaves and roots. All this is dependant on temperature (keep them at the sort of temperature you'd feel comfortable at), and they need lots of light and to be watered well (don't drown them in water - if they're under water they'll die!). If you want to watch the seed germinate, try putting a roll of blotting paper inside a glass and filling the glass a quarter full of water. If you sandwich some seeds between the glass and the paper to hold them there, they'll be able to get their water from the paper, and you can watch them grow through the glass. Watering plants with baking soda or vinegar will probably affect the way they grow. Baking soda is very alkaline, and vinegar is very acidic - both these will alter the way the roots of the plant take up minerals. Usually plants like a nice neutral soil (not basic or acidic), so adding vinegar or baking soda won't make them very happy, probably because they're getting not enough or too much nutrient of one sort or another. Plants need very different sorts of food to us - all they need are a few minerals and water - they make all their food from sunlight. Most of the stuff you find in the kitchen probably won't help them much, and may kill them if you add too much. Why not try an experiment with your beans? Hope this helps, All the best, Carl
