We use a shurflo diaphragm pump (12V) and Naandanjain Hadar micro sprinklers (they have nozzles for mist and drops) to spray our biodynamics and some ferments. So far we didn’t spray any more sensitive things like compost tea. but our neighbor prepares a sprayer for that with a similar setup. We do have an old 12m boom sprayer, but depending on the situation we also use an IBC tote and just switch the pump over. We are in the process of welding a front loader attachment on the sprayer, so we don’t have to put it in the three point anymore.

Pumps are available online, we get the nozzles from a local greenhouse/ lawn/irrigation company.
