Sprouting seed balls indoors

Hey guys,
anyone tried this before? I was using seed balls this season in my vegetable garden, and although I had quite some success, I feel like it would sometimes be beneficial to sow already sprouted seed balls in the garden. I'll be trying to grow a commercial garden next year where spacing will be very important and just sowing seedballs randomly isn't ideal. Wouldn't it be great to see just how many seeds have actually sprouted (and in which balls)? It'd be much easier to experiment indoors. Most importantly, you can then space them however you want!
If you have any tips, please share them

Best regards, L

Lovro Kancjan : The term Seed balls is so loose as to have very many different meanings to different people !

Generally, seed balls hold one or more seeds and were expected to be hand broadcast across the area you were using to grow a crop ! A common type of seed ball
that I have seen was made by recycling shredded paper often dyed to contrast with the soil and wetted with 'compost tea' and some other amendments, possibly
some perlight and clay to help form the ball, if these were made up ahead of time the seeds needed some protection from the tea saturated seed balls so as not to
sprout before broadcasting, if sprouting was suspected, more gentile application was needed !

Having said all that, I don't know why you want to make up seed balls if you are not going to broadcast them ! I would skip that step as to labor intense. Color me
confused ! Big AL
