I'll say this on the growth of mine, since switching mine to a pure diet of
@Matt Vanilla Gorilla 's gutload and moving them to my back porch there had been some pretty rapid growth. I was doing a switch up for the first few months of going between veggies and his gutload every few days. They were growing but not nearly as fast as they are now that it is just water crystals and just his gutload. I only know a handle full of the ingredients he uses but my goodness do they love it.
When I was getting low on his gutload last time I grabbed a tub of bug burger to tide me over until I could get more of his. I did an experiment and put some of both in there for them in the same dish. They crawled through bug burger to his and cleaned that side then moved over to the bug burger. I found that interesting to I tried his with some veggies at the same time after I got the next batch. They gave me the same results of cleaning the dish of his and then moving to the other food offered.
