Good for you for picking them out. Here is a bit closer view during breeding season:

This is from Wikipedia, credits to: Wildland at Russian Wikipedia, CC BY-SA 3.0. I have hundreds of my own photos, but not digital. Kodachrome era, long gone. One of these days I want to digitize the best of them, but have not yet done it.
The large beast is a mature male, maybe ~11 years old, the little one on top is a pup a month or so old, and the smaller one up front is a female anywhere between 5 to 20 years old. She looks as though she is still pregnant. All told, I spent about a thousand hours watching these beasts.
good on ya mate, I could not keep the girls healthy to the end with MC in Autopots. But I was a noob at it (arguably still am), so no doubt I could have done better. Anyway for now I am back to coco with top irrigation.
Jack's is really good stuff if you want to try it. You might be just as well off with MC 2 part though, the reason I didn't do that is that I could not get it in Canada in small enough quantities. I would not hesitate with either one. I will likely be trying to use up my other stuff and then stick with Jack's.
