It's more of a choice and experience really because Rockwool blocks are just a soilless substrate or growing medium.

uhm sure they do, some even do NFT in a 2'x4' it's not a problem , just a choice. My thing with rockwool is that it doesnt work as well as a normal root plug, but it does become necessary when you want to grow sterile. hope this helps ! đ

Worms in pot.Worms in pots. About a week after germination I have introduced about a dozen earthworms in the 10 liter bucket where my plant is growing. I read a lot about worm poo, but never I seen someone introducing worms in the pots where their plants grow. Anyone any experience? Why not?Week 2

Chicken PoopWe have chickens and ducks which provide all kinds of poop. I have a pile I use to age it for about a year. It is a mix of poo, oyster shell and broken down leaf mulch. I am not sure exactly what it adds as for as nutrients. Does anyone have a guess?Week 10

Soil recommendation? Typically use Fox Farms Happy Frog but price keeps going up and quality seems much lower, lots of sticks, not mixed well etcIs there any soil recommendations anyone can make that are good but a less pricey? Dont get me wrong, I love Fox Farmâs, and 38/bag isnt terrible. Iâm just curious if anyone has found a more mainstream soil thatâs as good of soil. I also think their quality has been worse latelySetup. Substrates
