Yeah, that's nice!
I could probably just start them in my net pots then.
...oh yeah man, you pot these up into net pots filled with something like hydroton or grorocks or even rockwool croutons and they would EXPLODE, lol, ...it cost's about $8.00 bucks to get one of those ice-tube-trays delivered from Amazon although you can get them from Walmart if you look for them for maybe $5.00, hence the name, and it'd cost about another $8.00 for a bag of vermiculite and, it you wanted, you could also add some kind of rooting hormone although they will root just fine without, ...i actually mix up some cheap Greenlight rooting powder and honey for my own version of rooting gel, lol, but for real you don't really need anything but the vermiculite.
...it's all explained in that thread i linked to where you can do enough research to see there are MANY who have used this passive wick style method for many years, ...actually, it is adapted from a thread from the old Overgrow site, ...a member saved it and passed it on and i'm grateful i found it.
...anyway, if you read that thread and you still have questions i'd be glad to try and share what i have learned over the years, ...it's pretty darned simple though so i expect if you read the instructions, which i believe are on the first page of that thread, you will have enough information to make them work.
peace, bozo
