So after having them in my equipment for a while, I do a review of the eazy pyramids.
EDIT: copied it for further discussion to the right place in the rms system - now found here also: eazy pyaramids review
They are bonded substrate made of coco fibers. Pressed into the shape of pyramids.
I have the big ones found here: eazy pyramid
Details and marketing blabla can be read there.
First things first: They are expensive compared to "normal" coco or rockwool.
But that said, they deliver a great deal in the growroom.
To set them up you do not really need to watch ph and nutes too close. Just soak them with your nutes and place your cube/plug ontop.
Put them in a tray or onto a ebb-flow system and you are set.
They are not very high (26cm) and you gain a lot of headroom for your plants.
They really promote root growth very well and the shape cares for an even water distribution.
The big ones can hold up to 2.5l of water, so you do not have to care about much in the first weeks.
You can place them very near or even stack them a little together to save light/space in the beginning.
But that changes very fast as the plants grow and need more feed.
There are then more than one way to handle them.
The only thing i do not recommend is, to let them dry out too much on the surface, they become hydrophobic fast and then topfeeding will distribute uneven, if not applied slowly. Ebb flow, drowning them until soaked is possible as well. Just prevent drying out.
The way I chose was to simply treat them like a normal coco substrate. I feed nutes with every watering.
Although not necessary, i recommend to adjust the PH at least approximately - they buffer well.
The buffering is very interesting and long lasting, because of the nature of their shape.
Drying out from top to bottom, they expell all excess of nutes.
They were cut in half several times and the interior was found completely free of salts.
Your plants always get the optimum amount of nutes they can take. I never had to deal with all the problems that come with excess nutes.
If you go over the top, you'll simply end up with a mineral crusted surface. But plants grow nicely.
Now after some years of testing them, I can definitely propose they work. At least the way I treat them.
The plants sit in runoff and don't care at all. The pyramids just suck up and distribute the needed nutes as needed.
So now that the excess problems are gone, there is still the problem of underfeeding.
I never had something telling me that clear what was lacking. Because you can rule out PH and excess Problems, you can clearly interpret what the plant lacks.
The deficiencies have never exposed more isolated and readable to me. And if you feed them like I do, you simply adjust you nutes and go on. What may not be needed in the change, will simply be expelled and dries on the surface.
So what are the negatives?
Well - if theres not taken precautions, there will grow moss and algae on the sides of the pyramids, as long as theres just little excess. This shows you on the one hand, that you are on spot with your nutes. But if you don't care and that dies off you can have mold on the pyramids sides.
That is undesirable, so you can go different ways. Overfeed early, so theres an excess salt layer (not visible, but it's there) that prevents growth, or do some kind of treatment of the surface. I applied disinfectant, pure isopropanol and i even burned the mold - all worked. If It happens I recommend to apply some kind of alcohol on the complete surface, after watering. It won't go into the pyramids too far and will not affect the plant.
Also remove moss and thicker layers of algae from the surface, as they prevent proper working of the expelling mechanisms. The surface cannot dry out as well and the stuff prevents the salts from being sucked out and dried off.
Another thing is large plants. The larger they become the more you have to feed. 2.5l is not very much and I hat times when i needed to feed 5 Times a day. Outdoor even more.
And because the pyramids are very light the plants may fall over. One big outside lady also simply was blown away with the wind once. So be sure to somehow fixate them with big plants.
This last pic shows you nicely what a pyramid can hold, although it is so small, and you well mey need need a fixture
For more questions, theres an Indoor Testing the eazyplug pyramid mini thread and my ongoing journal.
