anybody tried polymer crystals

i did a little reading on the crystals to see if it was possible to use them...one site claims that they are potassium based and break down as fertilizer instead of salt...they also claim to protect plants for 5 years...just thought i would pass along the links...anyone actually used them?

i use them all the time on my outdoor plants ,as it gets hot in an aussie summer ,dont know about the pottasium side ,but they help heaps if you cant get to water as often as you should.

I use them to make ona buckets(air cleaning gel scent)---one bag will make like 200 buckets.

thanks for the replies

could you tell me where you get the ONA stuff from i cant seem to find the right stuff anywhere

you can find it at any hydro store...

i dont have hydro stores in my area. is the stuff on HTG supply what your talking about? and if so what one has the power i need?

get the liquid and make your own gel buckets----you can make them as small as a cup with a comp fan or you can even go beyond 55 gallon---a friend of mine made one with a 55 and used a small squirrel cage blower on top---takes 50 gallon of water---one gallon of ona and half a bag of soil moist crystals.
