  1. For the porous rocks, you can maybe burn it and rinse for reuse. Although I'm a gardening beginner, but rocks and glass stay the same unless the temp is in the thousands (if they were dry when you start burning).

  2. Not the greatest review. Your words at times contradict your blog, even your blog contradicts your blog. You've written and stated that rockwool is not easy to dispose of then under benefits you've written, "easy to dispose of"… This didn't help me to understand what might be the best option for me because you haven't described your system(s) setup. You've presented the results and none of the context.

  3. Technically using Coco Coir to grow in is NOT hydroponics. Coco Coir retains water for days, Hydroponics is the art of growing plants roots in air with the water/nutrients being added at different parts of the daylight growing time frame. Coco Coir retaining water for days even with the addition of Perlite is no different than using mulch. You still must add nutrients but it is simply not right to state it is a hydroponic medium. Sorry.

  4. I use homemade worm casting for starter plugs. They actually hold together well along with the roots and can be transplanted to net cups with clay pebbles. I will not use coco coir because palm oil, made from both coconuts and palm nuts, is one of the main causes of the wholesale destruction of rainforests in many parts of the world, especially in Indonesia.

  5. I was working with some perlite today and was watching the dust and thought mesothelioma from asbestos I believe it is made in the same fashion and basically rocks also..I held my breath

  6. It's-'Pronounced' COY-[R] … But Thart's-[OK] … Still No-One On-The-Planet Plays-Like-MOZART … &-Some Can't-Even Match Scott-JOPLIN's Piano-ROLLS Made Four-Months Before-His-Death … So-There's Plenty-of-LATITUDE To-GROW So-to-Speak!!!??? >(*U^)< (Joke)

  7. How about marbles i need to fill a 4 by 8 tray but don't want to spend to much on hydrton. I know the the media needs to be ph balanced, so how about marbles, shouldn't impact pH, and they don't float, and not easy to break like hydrton. Let me know if anyone tried this yet.

  8. What happens to coconut husks in the tropics is that they are not thrown into land fills but are levt to decay and degrade in the environment.
    Some people use the coco husk split in half for orchid pots.
    These things are not fast food wrappers nor disposable diapers and are 100% biodegradable.

  9. Cool video! I'm inexperienced, but maybe a solution to cleaning the growstones would be to hit a pile with a propane torch or throw them on the grill/oven and burn the roots? I happen to have a lot of perlite, some coco coir and a small amount of rockwool. Do you think using a cutting from rockwool (thin standing rectangle in the middle of the netcup) with the seed in it, surrounded with a mix of coco coir and perlite around it would do alright?

  10. Currently got a coco coir and soil mix iv been using for around 2 years, not only to recycle but to upcycle, iv used it on every thing from tomato's to root veg, but as now its coming to the point if being neutral in pH ect I think I might have to start making plugs from it but would coconut husk fresh that it be an advantage
