Hydroponics is a method of growing in no soil. A media that can be used to grow plants in water is chosen. This can be perlite, marbles, rocks, pon, or leca for example. Depending on the type of media you choose, nutrients may have to be added to the water every so often.
Rules when switching over from soil to hydroponics:
1. Rinse off ALL traces of soil as they can transfer soil borne pathogens.
2. Rinse media with water until it runs out clear (not needed with pon).
3. Use clear container so that you can see water level. Place plant roots in and fill with media. If lava rock, fill fully to top with water; if leca or pon, fill only a third of the way with water.
4. Plants may exhibit shock and sulk with the transplant. If so, put in higher humidity.
Tips for Fresh Cuttings: Root in water prior to Leca and wash prior to potting in media to avoid rotting pathogens from forming in hydroponic setup
Proper technique = Be as sterile as possible, act like you are working in a lab.
My Favorite Hydroponic Mediums
Leca: My favorite. Pros are that it absorbs the perfect amount of water, is airy, and is amazing to work with. Cons are that it is more expensive than Lava rock.
Lava Rock: Pros are that it is cheapest, prevents pests and allows roots to attach well with its rough surface. And, it is the most airy. Cons are that it absorbs less water but this can be good for people that over-water.
Pon: Pros are that it adds lots of nutrients. Cons are that it costs a fortune and absorbs too much water for my liking, so not as airy.
The Perfect Mix = Leca + Lava Rock
