Growing in 100% coco outdoor

Ive been a coco grower indoor for many years with no problems, growing outdoors in coco I'm always getting root rot, live on the equator its hot as all year round. I was thinking instead of pots to dig a 20 gallon hole in the ground and fill it with straight coco. Can anyone see any problems with this?

What about a 50 or 100 gal smartpot - above ground?

Ive tried that, still got root rot, temps here stay over 40 degrees all year round. Even used 50% perlite. I'm thinking buy putting the coco in the ground, the root mass will stay cool.

I put my pepper pots sub terrain. I live in the desert. You could bury half a fabric pot if you want the air flow.

Too hot for strait coco, have you tried soil?

yeah coco outdoor works great for vegetables etc
i love to circle the pots with pine spikes all around it to isolate the pot from the outdoor heat/coldness
but in very rainy country it can create problem because of the rain rinsing the coco and the nutrient/ph
the best is to do it in a greenhouse

I lost a couple to root issues. Roasted fabric/rootball in Norcal sun, and I was a noob.

Its fun when it works.

So what's the consensus, would digging a hole work?

You can over water coco. You don't want it to dry as much as soil but it needs to dry some between watering. Perhaps it's rain?

Drainage. The ground would have to drain really well IMO.

If you can dig a trench to the hole and bury a drainage pipe that pops out the side of a hill then line the bottom with some river rock for good drainage something like that could work.

Maybe landscape fabric above the rock layer to keep the roots from plugging up the gaps.

What if I mixed the coco with half the native soil and treated it like soil.

Watered every few days with a lower strength nutes

I agree with @Renfro, put a drain from the hole to an exit point and don't worry about how much water it gets.

Probably a bad idea since they each want their own pH, not sure thats the way to go.
