Backyard Aquaponics
A place to discuss aquaponics

Al, i like ur acid/base post recital. Like u, I tend to have to repeat things to myself and in print a few times to fully understand them. That whole reinforcing thing.
Regarding pollination of tomatoes, had an interesting chat at the vic AP meet with Shaz, a hydro grower of some 30 years. (Laurie's wife iirc.)
When the petals of the tomato have curled right up to where they meet the stem from which they originate, there will be a tiny 1mm green bit at the end of the stamen(?) This green bit is the sexual/repoductive part of the flower. If u wait until the morning dampness has gone, then tap ur flower, it will cause pollin to fall down onto this bit and booya, fertilised flower. After that mucho tomato.
Try it and see how u go.
