Ok let me share some thing with you. Most of it will recognise what it is but as to if any one has made use of the properties of this substance?
Gel beads and you can also get them as chips called artificial soil. For Isloo residents, Grow More, F8 Markaz. Now look at the next ones, lot of pain with this baby it has to be fed.
Any way up to you all if you want to go into Hydroponics but i make use of it for another purpose. These gel beads/chips can hold up to 120% water. Coconut coir (a natural fibre extracted from the husk of coconut) is also good at retaining and acting as a wick. (Izhar coir is a neutral kind of substance with may be acidic properties when and if it decomposes while Peat is an accumulation of partially decayed vegetation and acidic in nature with food value.) Khair i lay a layer of coir near the bottom of my pots with a few beads (5 to 15 depends on pot size) cover with soil in which some coir is mixed in and plant. When you water, the water that flows out of the bottom instead gets retained by the beads which as you all can see holds a lot of water, When the soil dries out i have a emergency water ration in the beads. The moisture from the beads travels through out the soil due to the wick effect of coir, coir also allows the beads to expand. Thats how i deal with the requirement of water of all my spoilt brats while i rest. Coir also should be applied at the top as mulch if you are facing water shortage it cuts out evaporation-al losses. For palms and bigger plants, round river and sea stones can be put down as mulch. The stones stop the direct sun from hitting the soil, acts as home to beneficial insects like spiders and lizards. Which in turn can eat many times their weight in harmful pests. Also gives a decorative effect. Imagination is the criteria.

PS. Still not solved the PM chakkar you may have to send the PM to get the ball rolling.
