I have used the Jang for three seasons now. My opinion of it is a lot more nuanced than it used to, but still positive overall. The price is obviously the biggest downside. The adjustments are also not entirely intuitive, and takes a lot of fine-tuning to get right (the depth adjustment, in particular, is quite backward to use). Singulation of small round seeds (such as most brassicas) is absolutely perfect. It works fairly well with coated seeds, although you have to open up the chute a little more so singulation will not be perfect. It does an ok job for irregular seeds (raw carrot, beets, spinach), and is completely useless for the larger seeds such as beans and peas. In fact, I am buying an Earthway just for peas.

BTW, you would not need the whole set of disk. I own five, and the X-24 is what I use about 80% of the time.

Also consider where your product is made.

I do have a solar powered electric fence around about 2.5K square ft of home garden. One wire about nose height for deer (waist height for humans) and one wire about 6 inches above the ground. Works fine until the neighboring and wild vegetation gets pretty dry and tasteless to the wild animals in mid to late August. Then nothing short of 10 foot fencing or chained dogs will keep the deer out. I also plant an extra patch away from my garden to feed the wildlife.

Lately, I have been taking an interest in the role of earthworms and mycorrhiza in fertility, both of which are not quite compatible with the constant tilling we do in growing vegetables. A no-till system would be perfect, but I do not think it would work particularly well at my scale. The solution, I think, is long-term (18 months+) undisturbed green manure. But for me, until I have gotten on top of perennial weeds, it’s not really a possibility.
