well here is a start im looking into the crystles i mention 1st thing i founs interesting not about growing but its worth reading
The Patent states that the product is made of: 'A superabsorbent polymer is a resin capable of absorbing water up to several thousands times as its own weight. These superabsorbent polymers are prepared from water-soluble polymers, but have cross-linking structures which render the polymers water-insoluble. By taking water-soluble ethylenically unsaturated monomers which readily undergo vinyl polymerizaton, such as acrylamide , with the use of cross linking agents, a polymer can be produced that is of uniform small size, has a high gel capacity, is highly insoluble, but highly water swellable i.e. a superabsorbent polymer. (Gel capacity refers to the property of the water swollen polymer to resist viscosity changes as a result of mechanical working or milling. The patent says the particles are "less than 4000 microns but greater than 50 microns" in size. )
im thinking maby if thay hold TOO much water thay wont works, like 1000's times there wight just might be overkill for the hempy bucket lol
---EDIT--
ok so got a lil more info
Are there different types of super-absorbent polymers?
There are about 800 to 1000 different recipes for these polymers - but they are divided into two big categories: polyarcylamide and polyacrylate.
Polyacrylate (called in the industry PAC) are used in disposable diapers, sanitary napkins, etc. and are capable of holding a huge amount of water - between 600 and 800 times its weight (purity of the water determines this range - the more dissolved solids in the water, the less liquid the polymers can hold).
Polyacrylates are usually made with sodium and are more environmentally friendly, breaking down first into ammonia salts and then nitrogen and CO2 in about 4 to 6 months. They are often sold with an environmentally friendly green label and retail for around $10 to $12 per pound.
In contrast, polyacrylamides (often known as PAM) absorb only about 300 - 400 times its own weight in water, use a variety of potassium molecules for cross-linking, and take between 5 and 7 years to completely breakdown. Because of the lower absorbency and longer time to breakdown, polyacrylamides usually sell for around $6 to $8 per pound. -
seems like 300-400 times its weight in water and a 5 year breakdown would be ideal for perlite hempy buckets, u wouldnt need to use very much so seems cost effective aswell
has anyone ever used this stuff b4 than can comment on how it works and what its like use it. if its a plastic sounds liek just as inert ass glass, cept for the potasium or sodium it would leak... hmm ima read more il lmost anythign else i find that can shed some light on it
---EDIT----
and some more growing specific info
How much do I use?
Consider that one cup of dried polymers (250 ml) will absorb 100 liters of water (about 24 US gallons). This would likely launch your plant out of its hole in a matter of minutes!
That said, an appropriate amount will be significantly less - between a teaspoon and a quarter cup of crystals. It all depends on your environmental conditions. In drought situations (no rain for more than 28-days), you want a lot of polymer crystals to absorb any water they come in contact with - and it is unlikely that any single polymer will absorb its maximum potential. A couple tablespoons to 1/4 cup of polymers is recommended for this sort of environment. In more "normal" meteorological conditions - a rainfall every seven to ten days - your objective is likely to minimize stress between rainfalls - and one to two teaspoons would be the more than enough. --
looks like alot of real life testing will need to be done to incorprate this into a hempy bucket, but im starting to think 100% perlite or sumthen else might be beter. my goal is to only have to order the nutes and get everything else in a walmart / home depot. but man 1 cup absorbs 25 gallons that prety insane
---EDIT--
well seems i was right these might not be best for hempy, seems there main aplication is for outdoor crops to hold water between rains, thay can be used in soil/soiless mixes for indoor container pots. BUT i found
Important Note – Water absorbing polymers are not appropriate in self-watering containers.
and with hempy bucket being a self watering wick system, it will not work the polymers will stay 100% saterated at all times and hold all that water way way longer than the res at thwe bottom of the bucket. and will suck it dry everytime, so the watering would have to be more like how u water soil plants i think. and the best thign about hempy is the water everyday / replenish the res. even at a small amount i think the polymers are just too potent to work with hempy
