The way I'm seeing it, the tubers may not likely be that big and secondly, If the tubers are not well covered with sand/ground during production, it will affects the quality of the yam. .
I'm seriously interested with the outcome.
Kudos.

Afaaaaa. They yam don ripe? Lol

My vertical yam farm.
1st pix- When I was mixing soil with manure.
2nd pix- When I was transplanting from the nursery.
This is just a practical of vertical yam farm in my compound as I have 2,200 heaps of yam at farm that I planted almost the same time with this. Those ones have not sprouted as they didn't enjoy watering as I water these at home.

If he plants on the ground, the land will be tilled, and the number of stands that little space will contain will not be worth the energy and time put into this. Sack farming has its advantages.
- No competition among plants for soil nutrients, water, light etc. Each plant has its own space to thrive.
- It is easier to control weed and carry out other management practices such as mulching, manure or fertilizer application and so on in sack farming than planting on bare ground
- There's no limitation to farming with this method, as it is possible to farm even in urban centers, on concrete floor space and so on. You can't till the concrete floor of your compound to plant yam, but with sack farming, you are good to go.
- With sack farming within your neighbourhood, there's no fear of attack either by herdsmen or bandits, at this time that everyone is scared to go out into the bush to farm, this is your best bet.

My brother, thank you for your concern and contribution, that bag does not look like it's not washed, we know how a bag of cement that's not washed will look like. Talking about planting in sack bags, I don't think it's having the kind of dangerous picture you painted when it comes to using it to plant. I understand we don't have quality control measures here, but they do in America, and they permit the use of sack bags for planting. All the vertical farming and soilless farming being practised in advanced countries, they use plastics in planting, plant roots extract the needed nutrients from the nutrient solution contained in a plastic, this one appears to be more dangerous to me than sack farming, yet it is certified safe. In sack farming, there is soil medium around the plant, the sack is not even touching the plant. At times when you are tilling the soil, you'll come across many buried nylons, polythene bags, plastics and so on, yet we plant in the ground and eat the crops that come out of it, Sack farming was approved by FAO itself, you can check it out.

Okay. By the way I started around January. I was just watering it like once in a week until rain takes over.
This is more like an update. See the link to when I started. https://www.nairaland.com/6927505/vertical-yam-farming-diary

micellgevity:
It was in January during the dry season. If I planted directly on the ground, the water I was using to wet it would be sinking and that would be a waste.

micellgevity:
It is not too late. As a matter of fact, they plant yam twice in a year. One around January/February. These are the ones harvested around August/September. The second ones are planted around April/May, these ones are harvested around December/January. But the ones planted in January/February will never sprout for lack of rain until around April when rain begins. The benefit is that it would have been ready to sprout upon getting any little rain. Though, this I planted at home is getting water once in a week, unlike the ones planted in farm, that is why you can see it sprouting now with leaves. The ones in farm will just start sprouting without leaves around this period.
My source of manure is sound from refuse dump+ my rabbit faeces.

Sack farming is being used to Successfully Cultivate Yams in Nigeria.

Sweet potatoes are also being Cultivated using this method in other Countries
