Alright chief. Look I don't know much...anything about those plugs. I did the overnight soak, then paper towel and then into soil. Just started my 2nd grow and just now I see the 5th seed has germinated. That's 5/5. Although 1 did give me trouble in the last week!no feedback?
I just said I'd weigh in on what I found with the 1st grow with respect to transplanting. When they were small it was easy. They didn't suffer at all. They are robust. They don't call it weed for nothing! My mistake was not putting them in their final pots early enough and having to transfer bigger plants. They were a bit shook looking afterwards but did recover quickly. Get them germinating. Once you have a root, worry about the leaves coming up. As soon as there are leaves get them under a light. And optionally repot as they get bigger depending on the pot. I don't think it matters how many transfers are involved in this!
As I say I don't know about plugs but you mentioned putting them 3-4" deep. I presume thats after the stems are up. Sounds too deep for a seed.
Best of luck. Are you doing a journal here? What ye growing?
