Thanks for all the advices. I did a search for Penterra, my local garden centers don't have it, 40 bucks on Amazon seems kinda pricey. Doing some googling I find people using Agar Agar and other various things as wetting agents. I happen to have Agar around the house, ever try using it? I think I'll give it a shot first and see how it goes.
Otherwise, yes I will be putting quite a bit of sweat into the ground during the rainy season once things soften up.
