To help add more seeds per tray I made little baskets out of mesh material. I can get two baskets per tray so I can actually have three crosses now per tray.
When making these baskets try making them tall enough to reach the top of the tray but not to tall so the trays will still stack on top of each other.
To keep help keep crosses straight, I label each usable tray with a letter. Then to each "basket" I add some colored thread. Then as I add the seed I write the crosses down as follows (for the tray shown)
Now after you fill all trays your ready to start the sprouting process. The trays hold about 2 cups of water so I add on capful of H2O2 (Hydrogen Peroxide). This helps ward of mold and I've been told it also helps the sprouting. I pour the water in the top tray and let it trickle down to the holding tray. I do this once per day and use fresh mixture everyday. I've had some seeds before start sprouting after 9 days. Since I do both tet and dips I try to keep all the same ploidy the same in each tray, just in case I pour the water to fast in the top tray and the seeds wash out from one basket to another. Better to have crosses of the same ploidy mixed then have tets and dips mixed together.
So for the first 12 crosses I'm starting this year here is the list
A - JERRY PATE WILLIAMS X SDLG
A red-JERRY PATE WILLIAMS X OVER THE TOP
A yellow-OVER THE TOP X JERRY PATE WILLIAMS
B-JERRY PATE WILLIAMS X FIERY VISITATION
B red-JERRY PATE WILLIAMS X SUSAN PRITCHARD PETIT
B yellow-JERRY PATE WILLIAMS X GEMINI JACK
C-JERRY PATE WILLIAMS X BOYSENBERRY TRUFFLE
C red-JERRY PATE WILLIAMS X SDLG
C yellow-JERRY PATE WILLIAMS X MULBERRY CONNECTION
D- PLUM PLUME X JERRY PATE WILLIAMS
D red- ALAXANDER'S RAGTIME BAND X EYE BE DARN
D yellow- SOFT TENDER TOUCH X EYE BE DARN
I just sit the sprouter on a table top, somewhere out of the way so it doesn't get knocked down and check it every day.
