What are the best wetting agents to use? Granules or the liquid form.

Any other tips on usage would be appreciated.

Thank you

if you want this for garden or open soil areas why not try watering with grey water that will give you a similar result, after all as far as i know wetting agents are mostly a detergent type material.

most gardeners from here are over at:

Otherwise either the wetting agent granules or the liquid wetting agents are both fine. The water granules that swell up, need to be mixed deeply into the root zone. To prevent water loss apply lots of mulch.
