Wet/Dry Substrate?

Is it possible to have a coco coir/verm substrate be wet on the bottom and dry on the top? If so what do you do, lightly mist the top? How do you tell if the top of your substrate is to dry? Is it OK to touch the surface or is that a bad idea? What is the ideal feel for the surface of the substrate?
Thanks

It is possible, if the air exchange is stronger than the difusion of water in the media. I don’t think its ideal to touch the substrate, as it can introduce lots of contamination. This part doesn’t need to be sterile, but it doesn’t need to be dirty either. Maybe you could reduce the air exchange, or move your box to a more humid area of your house, so there wouldn’t be so much water evaporation from the substrate. You can mist it, but be careful, because water accumulating in the bottom can “drown” the mycelium.

the best way is to get your sub prep down. it is possible that your air exchange is too high. misting to keep the surface ideal while the sub is already too wet can lead to problems for sure. how do you know that you sub is wet on the bottom? are you using a liner? can you see standing water? How did you prepare your substrate?

I did Bodhi's bucket coco coir Tek but I had to add a lot of verm to get to field capacity. I did not use a liner as per Bodhi. I'm glad because I can physically see the moisture drops on the sides and bottom. I'm doing a big grow and everything looks very happy and healthy. Except for the 3 dead soldiers that are no longer with us. (RIP) I am over a week in and I have not had to water, I was just about to when I decided to throw a grow light on the bottom and sides and realized that no more moisture was needed. I probably did the mix to wet, not enough to kill but close to right. (I Think) I am not sure how to gauge the dryness of the top of the substrate. Any thoughts? Can you leave the top off your tub completely while you are at home to balance out the moisture? I feel confident in everything except moisture control and LC solutions but I love growing mushrooms and learning something new and a little hard is half the fun! I bought a new glass top oven and also a cuisinart Hot Plate so as not to ruin the new oven. The hot plate was top rated and I am very interested in a portable cooking surface, never even thought of it before. If I do well on this grow then I can relax a little and know I am headed in the right direction.
Thanks for getting back to me
I still want your crazy LC factory thing! LOL!

Oh Yeah almost forgot I had a agar plate and I was trying to isolate the bad guys (Trich) and sure enough I found a good sized spot of Trich on the outside edge of the plate. I let the mycelium grow out with the intention of using it. Any how the mycelium grew out to the edge and killed the Trich! I did not no that could happen! Cool! Go Mycelium! LOL!

You should never use the myc that had trich next to it, you should make at least 1-2 transfers until you have nothing but cube myc on the plate and then you can take a wedge and use that. GL

The cubensis mycelium may have outgrown the contamination, but their spores are still viable inside, so probably the will grow. I don’t think its good to leave without the lid, because it is a perfect environment for basically everything to grow, and while some contamination is tolerable, too much can be horrible.

If you are seeing green spots that doesnt mean that the green is in those spots only, the green is actually only spores and the organism itself is white like myc and has already a firm grip on your substrate.
Slightly bacterial cakes and bulk substrates can still fruit but if mold is sporulating on your substrate then you know it´s game over
