Marbles, gravel, coco chunks, rockwool. There are many other materials you can use other than hydroton but they all have their own quirks.

My very first indoor grows were based on aero and nft designs I got from this thread

Harvest a Pound Every Three Weeks!

Outdoor growers are heading inside now so I thought if might be a good time to start a thread on how you can harvest a pound every three weeks from a 7x8' closet. I'll take you through my process from start to harvest. What is different about my system vs. others? 1) 3 separate Aero/NFT...

If you want to grow in a medium you can do coco or straight perlite. You could also do dwc in straight aerated water, nft in a flowing channel, or aero hanging in an air chamber.

No I mean like medium as in the thing I put above my rock wool for my kratky bucket.

I've never grown kratky method. I thought that was where you just let the roots hang into a reservoir that is not aerated or moving. You could use a foam insert cut to the right size. You can make them yourself out of floaty pool noodles....but if you keep too much moisture around the stem it can damp off the stem and kill the plant. I've had damping off problems with neoprene sleeves when growing hydro.

I grow in coco now. But using kratky bucket for some lettuce, gotta cover top of rock wool but don’t want to use those clay pebbles

You can cut a plastic lid or piece of black garbage bag. They even make plastic covers fit to rockwool cubes. Google Rockwool caps.

Thats not really true. I use perlite in a 3.75" net cup. Only a little falls through while youre filling it, mostly the smaller particles and dust. If you pack it down a little once the cup is filled it stays in better.Once the roots start growing they wrap around the perlite at the bottom of the cup and hold it in, making it so there is no room for it to fall out.

I root clones is a 3.75" net cup of perlite, sitting in a 16 oz party cup partially filled with tap water, so the water just touches the bottom of the cup. It works like a mini kratky. I get roots growing out of the net cups into the water in 10 days. No cloner, no rock wool, no rooters, just straight perlite in a net cup. The roots lock in the perlite at the bottom of the cup.

Perlite is nice because its draining capabilities are so good. It really only holds moisture on the surface of the particles, everything else falls through. Water wicks up through the perlite a little and the cut end stays moist but not wet, with plenty of access to air. I havent had any damping off since i started doing it this way. They stay in those net cups their whole lives, develop good root systems before i ever put them in to flower.
