Peppers aren't as easy, I find. They clone in much the same way as weed and i treat them as such. Worth it though as the hot peppers seem to be so variable when grown from seed.
I clone them in root riot cubes in a heated prop under cfl's, getting about 75% success in 2 weeks or so.
Over-wintering is a must for bonchi to get the fat stems required for a 'tree' look.
Garlic chives are bulbous and you just need to dig them up and split the clumps of bulbs into smaller clumps and re-plant. I believe they can be grown from seed but this would take longer.
Basil is another one that clones easily, only requiring a glass of water. When you grow it yourself, it can become a far different plant than the pathetic pots of seedlings they sell in stores. A single stem can produce a 2x2 shrub.
I grew romas the last 2 years in grow-bags but don't have the space now. Once tried it in hydro under my HPS and 1 plant outgrew the space in a couple of weeks!
Currently, I have 6 bell peppers, over-wintered on a windowsill (they say it can't be done, we will see).
Under the cfls in the propogation cabinet are 2 hot peppers, overwintered (1 cayenne, 1 Jalapeno, best of last years plants), 2 clones from them, just rooted and several seedlings taken from all of the above plus some ghost pepper seeds and a small basil shrub.
In 3-4 weeks, they all go under the 250w MH, some in soil, some coco, some hydroton flood-drain for about 8 weeks.
After that, they will be ready to come out early May (indoors) or early June (outdoors). Their final positions are undecided (want to build a kitchen window hydro-system by then)
