Rock guano is on cavemans site along with bat guano http://cavemans.co.uk/shop/ if you scroll to bottom of page it lists the N and P % of both bat and rock guano
Hopefully my Rock and bat guano will be here today.
Verdantgreen it says pellets on the site do you crush up the pellets of rock Guano or put them in as they are?
I ordered some in dec but it never came,luckily paid for it by paypal so got my money back but still was a pain in the arse.Don't seem to be anyone there,sent 3 e-mails with no answer,then more messages through paypal but none were answered.
