All the units so far in the green house started off as drawings.. some looked really functional until I made them. Some I had to make multiple times to get them in a working state. So even tho costs blew out of the budget and tooling cost heaps for all the stuff that didn’t work, it was rewarding. I now have some great working designs which reduced the cost of the units and increased the productivity for the given foot print. And now I have completed these units I am now starting on the new simplified cost reduced models I will have for sale in the coming weeks.
