What is P4?
'P4' is a safe, man-made, granular soil and compost additive which can absorb 100's of times its own weight of water. When incorporated into growing or planting media, the polymer granules store rain or irrigation water right where it's needed - at the roots. Plant roots colonise the millions of tiny reservoirs of water-charged polymer gel and can extract over 95% of the stored water as required, over an extended period of time. P4 can repeatedly absorb, store and release water for 5 years or more and is beneficial for all plant varieties at all growth stages and in all growing media.

The above photo shows how plant roots attach themselves to Broadleaf P4 water-storing polymer, from which they can extract stored water as required over an extended period of time. Click here to enlarge.

Close-up shows how plant roots actually grow right into and through Broadleaf P4, gaining access to 1000's of tiny reservoirs of stored water that is more than 95% plant available. Click here to enlarge.
