Hello seedbomb throwers.
I just want you to know about a useful discovery , as you know seed bombs are often made with clay powder , looking for decent stuff i naturally came across expensive terrarium clay , in the potters corner i also found sellers . dealers for natural builders materials like to offer 25kg sacks in their catalogue.
Cat litter is howerver available in many shops , its cheaper and in the ideal case is also made of 100% clay.Some bags even claim it is useful for topping up garden soil.In pet shops you can even get mini packs of extra fine clay for small animals.
Leaves only the question whether used cat litter might contain manure?
comment from translator :- used cat litter is extremely corrosive and will kill about anything that grows.
Hope thats of help for those in clay free soil areas.
