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 ! 🚀

PH-Problems in Soil
Before repotting, the pH value in the soil has always fallen to below 5.5. The plants always have an iron deficiency. I then repotted the plants and that worked well for 14 days. Now they are showing PH deficits again. The soil has PH 5,4 -4,8. What could be the reason?

Soil Amount Heavily Decreased
Hello everyone, I'm almost at the end of my first grow and I've noticed that the amount of soil in my pots compacted pretty heavily. How do I avoid this problem in my next grow? (Pictures show the beginning and the current state of the soil; ~ -7cm soil height)

What and why?
What are these and do I need to address it? I'm a couple of weeks in to my grow and just spotted these little critters when I was cleaning my run off saucers. I'm guessing there's more inside the soil are they harmful to my plants?

Mold on soil
I used BioBizz LightMix with Monsterbud Mix from Amnesia and some mycorrhiza in the hole of the seed. 3 seeds after 3 days still not germinated in soil. Had foil on top of the pots for humidity. Probably watered a bit too much. What should I do and will my seeds still germinate?

Overwatered cubes in hydro? Too close to the sun? or effect of having add
Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?

I believe this to be mycorrhizae that was moving between pots I had touching and premoistened. Any second opinions? Doesnt look like mold. Puts off no spores when disturbed. Does not have that mold smell. Anyone else ever see this?

Ok this is hard. Sf 4000 driver failure & idk what I did lol. Plugged into extensions and a surge protector but aside from flipping a fuse every once in awhile this came out of nowhere. Any help would be great or even just where to start. Already checked connections.
