Overall these are good points though I would not agree with every exact detail. Going as large as possible with your container, and getting your root mass out of the dirt with either a
smart pot or raised bed are very important. Even if you change nothing else on your grow other than those two things you will see a huge increase in yield. Actually had a neighbor this year that did exactly that after seeing my set up - switched form 45 plastic pots to 300 gallon
smart pots. Everything else they did the same - same location, same nutrients, soil, etc. They ended up getting almost 3 times as much yield out of the same space.
From what I saw this year with some side by side experiments even using a larger pot during early veg makes a huge difference. I'm going right from 4" plastic pots to 5 gal
smart pots, to the raised beds next year. In just 3 weeks I got 2-3 times as much growth with the 5 gallon
smart pots as I did with the 1 gallon plastic pots.
