is there any way to breed it so you dont have to keep going to the shops and buying it and how do they put spores into the granules?

The granule are just a medium the spore's are on the granule

ok a get that but whats does the process envolve to keep it fresh and not killing them

Heya Agito , how much are you putting on ? as a 360g packet lasts a good 6 months on a variety of plants at early growth stage i suppose a figure would be 150 plus . As for cultivating them laboratory/sterile conditions for the pure fungi , and the rootgrow are basically fungi compacted together small discs/biscuits , inoculated roots then reapplied , incorporated , imho is a far better approach , good luck .

Was that not one of the benefits of re-using your compost?
If you chopped it up then put a new plant in the new roots hit the old ones thus colonising the new plant with all the helpful fungi that the old one had.

I think you have to add guano etc. to the soil to recondition it and i dunno how the fungi would survive then.

Heya , its the trichoderma that remains , or more so less affected from transplants etc than help most rather than the mycorrhizal , i personally dont use Pm the product range but i believe both are in there granules ,

the guano imho would be conditioning the soil as a general high n fert with all smaller qty not really aimed at feeding you're fungi and bacto population etc . Personally i would only add more minerals or fungi/bacto teas to counter grow conditions or use as gentle teas and magic potions etc , good luck .

some times there are simple ways to make your product go further and if i could breed my own i would gift some to some gardeners i know and share the love

Sugar or mollasses? Yeast is a fungus isn't it and you use sugars to breed them up to huge numbers (Alcohol!).

Add a few teaspoons of mollasses per litre of water, 1 teapsoon of rootgrow, leave overnight with an airstone in it and then would then use it as a root drench.

If it doesn't work didn't cost bugger all to try, can't see why it wouldn't.

Freeze drying the solution back to granules and still being viable would be difficult I'm sure.

You could always add a little essence as well and as for sterility just use sterilisers for brewing and demijohns and you'll be incredibly sterile conditions. Both available from wilkos.

Heya , the main concern would be to the proper cultivators , breeding at home would create unstable hybrids mutants and new vigorous strains , multiple hybrids of trichoderma already make it almost impossible to carry out test without lab conditions to isolate the crap in there .
