Welcome to the fun of the green thumb group!
It's a lot of fun and very rewarding. So much easier that 40 years ago with mail order but the knowledge base we have and will all the available products makes it easy.
I grow outside and use only auto flower and get the trees thicker than an arm...
The butter knife is a good idea..
I use gloves handling seeds just in case even after washing hands as the soap could contaminate them.
Have nice tweezers to pick them up gently but the BK sounds good.
I had the same issue, had several big one but not big enough pots.
Now my solution is different then more space and pots.
I grow auto flower outside, takes up less space and killer dense fruits! Easier to take care for my wife who can't tend to
them full time when I'm out of town working...
