Making my own silvercolloid suspension like described here on icmag. Everything else could be optimized for seed production, my interest is to have enough seeds for many years to come so no no problem if I don't harvest one gramm of grass.How are you going to make all female seeds? This will also have a impact on the number of seeds. The more info the better.
Seems to good to be true. We're talking indoor, right!?! So let's say 10 plants under 600W should give me 50.000-100.000 seeds per your calculation!?!polinate just one of the larger or main colas and you will get some 5-10,000 seeds
obviously it depends on the size of the plant and on the size of the colas you polinated e.t.c, but its EASILY possible to have that many.
