Making Grow Bags with Double Decker Milk Crates to Grow Tubers

I have a milk crate LEGO garden where I grow my herbs.

It works a treat.

Since I wanted to explore the grow bag experience for growing tubers -- especially Sweet Potatoes -- I've tweaked the milk crate + weedmat system to engineer a deeper soil trough to accommodate underground tuber development.

Here's the DIY.

Here's a video overview:

And some background on some earlier milk crate activities.

They also used varieties of sweat potato that were specific adapted to the cold  and temperate zone that do not grow well in the tropics the Kumara from Atearoa rot in most of the gardens of the Viti Gardens only may survive in the mid year up in the highland gardens when it is not so hot or wet

I used to experiment with mound gardening per Polynesia and Melanesia horticulture, esp kumara. The experience has marked my later activities. The Maori used some smart hacks to grow sweet potatoes so far south.

if you use composed banana tree trunks as the soil with your potting mix this will give the tubers the right NPK balance to give the best productive results.  The old Fijian farmers used to bury their banana trees in pits and a year later planted yams in those pits with the best results.

I have now completed this post and edited the DIY.

Love them and your Pictorial Directions are wonderful, so easy for even myself to follow. Thanks so much Dave, for sharing yet another one of your Fabulous Ideas, for use of objects that may be upcycled.
