These are the same misting nozzles used by the EZ Cloner without the brand name. They are a bit cheaper this way and they come with a free drill bit to install them.
These Misting Nozzles Are A Steal!
At about $13 they are a steal. They deliver 31.4 GPH at 20 PSI but less in a low pressure aeroponic system which generally wont exceed 10 psi. However even at lower pressure they produce a good spray pattern. Larger orifices mean less problems with clogging but its always good to have some spares or you can use them to create multiple systems.
