With root development it can sometimes vary from plant to plant. It's more of a feeling out thing, and you'll see what I mean over time I'm sure. Conservatively speaking it's usually 2-3 weeks before they are out of that seedling stage with rapid root development. This time is critical so we don't want to starve those roots of the most essential ingredient they need to sustain that growth!
You'll also start to notice weight wise how fast they suck up water. It's harder in bigger heavier containers though. I like to start out in paper cups and move up in size slowly, but sometimes we have to just work with what we have available to us as well and just make it work :D
Keep on rocking bro, you're doing a great job! 👍
Awesome! Thank you for that man! This will definitely help out on this next tester run I'm starting! I'm going to be attempting bottom feeding, and with them being in 2 gallon smart pots, I need to make sure the root system is well established before I start to ensure the roots will stretch and seek the water from the bottom of the container!
I hope it will be a little easier to tell by weight from bottom feeding in smart pots too, because I have noticed that to be an issue as well!
Thank you brother, I appreciate your kind words! ✌🏼💚
