Hydroponic Media Guide: What Should You Use?

1. I used clay pebbles the first year of my experimenting with hydroponics. Found that the pebbles are not all the same size and many small size pebbles were going thru the holes in the net pots, floating in the water and eventually clogging up the tubes and creating problems in the filters. Also found that pea gravel - about 1/4" to 3/8" stone aggregate, washed and rinsed before the first use, works just as well, and is lot cheaper than clay pebbles. Saw no difference in plant growth between growing in clay pebbles vs. stone aggregate. Also, at the end of the growing season I was able to recover almost 90% of the gravel for reuse, but only about a half of the clay pebbles.
2. I know this vid is from 2013 but still wanted to leave a comment i live in thailand lots of coconut farming the husks are allways burned or illegally dumped
3. Bought some small lava rock to use. I do believe it will not alter the ph. Whats your thoughts?
4. How about using pea gravel from big box store? and will it effect the ph and by how much
5. this might be a fool question, but why not using soil for hydroponic?
6. how could u prevent coconut coir from drowning the roots? also, is it reusable?
7. personal experience, idk if I had the mixture wrong or what, but I noticed that the stem from was weaker growing in coco coir than in soil. and if your growing in hydro, FUCK, your plant will explode in growth.
8. really good guide thanks allot, thanks allot, it really helps understanding that a growing media is not just a magical substance sold in grow shops but something you can make if you have excess to coconuts or if your creative make it from sea weed or something .
9. I am using that noe coconut fibres
10. A few downsides "It does hold a lot of water, and if your not careful you might actually drowned your plants", sorry but this does not give me a lot of confidence in the product ? "In my experience if your doing it right it should be pretty safe"Why don't you tells us about your experience ? so we can avoid the issues that you had ? Stopped watching at 2:05
11. I have coconuts readily available to me. What can i do with it? I just rip off the husks and compress it? Thanks in advance
12. hi so I can used wetoasis to put my plant on to stand in the solution i notice the root melting when I put it in the water solution
13. I currently live in the Maldives so can get coconuts but very difficult to bring any other items into the island...  I really want to start a Hydroponic garden for the wellness centre on our resort... any tips would be good, have just subscribed to you too,,,, thanks heaps
14. I think people are missing something obvious when it comes to cleaning /sterilizing grow stones and L.E.C.A. Both of those products are made  at over 1,500 to 2,500 degrees F. Dry plant matter ignites around 400 to 600 deg F. I hypothesizes that if you put them in a steel can and set that in a hot fire it would burn out any organic mater in the stones while leaving the stones intact. setting them directly on burning charcoal might also work. I am just starting out on hydroponics so when I need to clean some I will give it a try. IMHO its best to not mess around with strong acids out side of a lab and wearing full PPE. They will bite you before you know it.
15. Can Stone Dust that is used in laying interlocking stones be used safely as a medium. 
16. What do think about actual lava rock (smaller pieces of course) like from lowes?
17. Like
18. Makinghydroponics seems like challenging especially if you have no experience, but it isn't.
19. Great video. Mind if I link to it for my site?
20. I am new to gardening and really new to hydroponic gardening. I have been reading and watching a ton on this subject. Your's is the best for learning why things work the way it does. Others just cover how to. Kudos to you. I am building my first DWC in the next few weeks. Will do strawberry.
