Peat moss + perlite = a soilless mix with a pH in the 4.5-5.5 range... why ever would you want that?!

That's a setup that needs a drip system; get yourself a bunch of emitter stakes which are quite cheap and stick them onthe end of the tubes for a more controllable flow.

Unless you are using tap water, add calmag.

It's hard to start in JUST perlite- I would have sprouted in a rapidrooter and then placed in the system when roots became visible, but that's just me.
