Totally i understand what you mean. Mynes always been pretty good not sure why its fellin melty this morning. When its not growing in size its developing larger bubbles. They guy i got it from could definitely grow some coral. I'd like to think I do alright but you never know whats going to happen especially after I had a tank white out the other day. Good old bacterial bloom came and whipped out my long tentacle plate wish I had it in a different tank.For sure man. I seen some real nice OG but for me they have been as you described.
I think it comes down to if you start with Garbage your going to end up with Garbage. OG is probably the most commercially farmed/fragged out shroom there is at this point.
Mostly cut and grown in unsatisfactory conditions im sure.
Only takes one bad apple to get passed on and fragged then you have a bunch of bad apples all the way down the line.
