This lady is a gem but sadly she passed away in 2013. Her grandson has been maintaining the channel and adding some new content here and there but she left a wonderful legacy on how to cook good meals on the cheap.
My wife and I have been learning how to grow and recently got the greenhouse into a useable condition.
It's only 8x12 but there is just the two of us now so that, and the grow lights in the house should be able to efficiently have a decent bunch of plants ready when we finally can plant outside in mid-May.
On the new building we are going to install solar panels and batteries so we don't have to rely on the grid. We are also going to have a backup woodstove, in case it is needed. We live in a farming area so we have access to reasonably priced meat and if necessary, I can start hunting again. We also have a lot of great fishing within a 5 minute walk.
Luckily we have around 5 years left before we are completely debt-free but we could easily survive on $1500/month which wouldn't be hard to manage at all.
