no, I mean 4 pots sand, 2 pots loam an 1 pots potter's clay granulate. It is only one recommendation. We made the experience now that a mixture 1:1 is'nt so favorable nevertheless. The mixture becomes too firm.
i ordered my antfarm and it arrived today. I ordered the 4 sand 2 loam and 1 potters clay but only the potters clay 2 sand and 1 loam fitted in. i have followed your advice and it won't work. The farm is 3/4 full but i still have 3 pots left????
Yes, you have to compress it a little and in the future you must sometimes replace some of the mixture. You will need it at many times! Believe me.
Good luck with the ants
