Some of them have great succeed.
but others contaminated.
It looks the pollutions are from inside of seed, I guess.
What can I do?
May I sterilize the seeds again and sow ?
Or may I give up TC culture and sow them on the other medium like moss ?
success seeds are all succeed (same packet from my friend )
high contaminated seeds , more than half of them are polluted and none of them germinated. These are imported seeds.
I cannot decide how to care.
