I did see this but for some reason didn't quote it, and I did take the advice and have started doing that xD every time I harvest something your post is in the back of my head telling me to hoard. (not really but yeah...)
It's actually good that the storage in this game isn't like the previous games because those ones were crazy. xD
Now you have a fridge and a toolbox and a storage box and it's like free hoarding all the time! Back in the day there was no such thing as storage. Everything goes in the shipping box or nowhere! And we had to walk all the way to the toolbox to switch tools!
You young'ns have all the luck.
(But yes, hoard lots. Even the weeds. Seriously, you'll need them.)
