why didnt you do a bulk method?
In the spirit of what Sr Verde was recommending, it would be a good idea to at least try bulk with a nearly spent cake.
I usually recommend people to stay clear of bulk until they've done at
least 1 PF-Tek grow.
I say that because I don't like to see people get disappointed in mushroom growing when they fail with the more difficult bulk methods that are out there. The people I've seen throughout my life try bulk mushroom grows (as their first mushroom grow) very often fail, and then they give up because they're permanently frustrated.
But as long as you've got mushrooms, and are able to make spore prints/liquid solutions with what you've grown (so you can hold on to the strain you're working with for years)...I'd give your idea a shot.
Something of note though is that over time, the dying cakes will become very vulnerable to random mold-spore/bacteria attacks.
Towards the end, the mycelium (that had been protecting the cake) has used up it's food source in the spent brown rice flour, and it's unable to stave off simple mold/bacteria attacks like it did throughout it's life as a mushroom-producer.
Just be careful in selecting your spawn cake(s) of choice.
Something I've done when trying to jump-start old cakes is:
1. meticulously scrape the top 1/4 inch off each cake (
it can be messy, but you're scraping off possible future contam points),
2. score the freshly exposed material lightly with a knife or fork (
this helps moisture penetrate the inner parts of the cake)
3. soak the scraped/scored cakes for a few hours (
not too long, as the cakes are frail enough and can't stand to be too water-logged)
4. take them out of their soak container, then 'roll' the cakes in dry vermiculite.
5. then take some wet vermiculite, and cover both ends of the cake in a 1/2 inch layer. This is called 'DECing' your cake, or 'Double-End-Casing'.
Works great.
I might spawn the used up cakes to a bulk substrate later on just to see if I can.
For use as spawn, I'd just do Step 1, and then grind the cakes up into small coarse pieces...then add to your bulk subs.
PM me if you want help with that in detail...
I'm actually working on a HUGE bulk Tek guide (which I'm hoping can be made into a 'sticky' eventually) that would help in these exact situations...hehe. It should be ready in a few weeks (still editing it, trying to make it easy to read yet comprehensive enough).
...sorry to hijack your thread!
