Reishi grain colonization / fruiting pics

I recently began my first attempt at cultivating Reishi (Ganoderma lucidum). I used an LC to inoculate my grain spawn jars (WBS and Rye) 9 days ago and it seems like they are very near full colonization. My only concern is that the mycelium looks different than other species I have grown before; the Reishi mycelium seems to be finer and grow less densely. Is this a characteristic of Reishi? Are these jars considered 100% colonized or should I wait?
Here are some pictures I just took of my grain jars:

maybe if your grain is very dry, but else it should be dense and hard to break up (read ''impossible'') after colonisation.

My jars do this too. It's pretty thin and wispy until it gets to 100% colonisation. Then very rapidly thickens, and if left too long becomes solid like forrest said.
You could just wait a day or so and see if it starts to thicken, and if so, rapidly spawn it

Thank you both very much for your advice. I will look for it to become thicker over the next few days, and I will probably spawn it to bulk if everything looks good

Depends on the species, actual G.lucidum is not actually common in cultivation as most cultures are miss identified.
But it is not uncommon in some of the species to start out wispy then get rapidly thicker like gray said.
Keep an eye on it and toss it if it turns any colors that aren't yellow.

Is there a significant difference between the different species of this genus?
Also, I am planning on spawning these jars to a 100% sawdust (hardwood fuel pellets) substrate when the time comes. However, I am now considering adding some coir to the mix because of a post I saw from RR... Would this benefit the Reishi? Or would it be more of a lateral movement?
I'll also add that I am not planning on supplementing the bulk substrate with bran or anything of the like. Instead I will be using a high spawn ratio (1:5) and running two monotubs

I'm about to do reishi on straight coir. I have not done wood yet so idk. I think reishi is a pretty tolerant mushroom though. I will be trying bags, trays, and tubs all with coir. I was glad to see that post by RR because now I only need to pasteurize!

where did you get your culture. Perfecti sent me reishi that turned out to be oysters. Looks more like oysters IMO. Oysters typically are light and whispy then turn dense after 100% reishi grows more like a blob of dense white cotton. fruit it and see....

I ordered my LC from Everything Mushrooms. It was labeled correctly and all, so I am really hoping they didn't send me something else, haha.
As the jars colonize further, the mycelium is definitely thickening up. I also realized after I made this post that some of my jars still has uncolonized areas. Those areas are quickly becoming occupied now and the mycelium is getting more dense in other areas of the jar (especially the top). I am going to give them a couple more days and then spawn to bulk, I think.
Here are some pictures I took this morning of one of my jars:

I would fruit a jar to verify the culture ahead of the rest. If the myc grows dense and is leathery its reishi.

Just thought I would update this thread with some pics.
These were taken the day after initiating fruiting conditions:

After 9 days of fruiting:

They seem to be coming along well, but there is a dusty yellow coating of varying degree on the majority of my fruits and substrate. Does anyone know what this could be? I think I have seen other Reishi grows on here with fruits that looked like that, and if I am remembering correctly, it was normal. It doesn't seem to be a contamination, but I have never grown Reishi before so it's hard for me to say, haha.

Fucking aye, man! I've got my first reishi try going right now. Still waiting for my grainmaster to fully colonize, so that I can do some g2g transfers. What are you using as a substrate? Is out just a mono tub?

The dusty coating is a response to it being in a closed in environment in my experience, a little more air will do it good, remember to keep the humidity up. It is not a contaminate, it is just how Ganoderma grows under these conditions, it is common in grow bags.

It has been a really enjoyable grow so far. The mycelium really is quite vigorous, but fruiting is a little slow, haha. My substrate is just pasteurized fuel pellets with some gypsum thrown in. I am working with two 66 qt. monos

Ah, that makes sense. Thank you very much for your answer.
Until now I have had poly-fil very lightly stuffed into the top two holes on each tub and a small fan running for FAE. The humidity of the tubs seems to have remained steady throughout the fruiting process - there is condensation on almost every surface inside the tubs. I'm thinking it would be a better idea to remove the poly-fil, turn the fan on low, and just mist when necessary.

Since I have been exposing the tubs to more oxygen I have noticed a decrease in the amount of the yellow dusty-ness in them. The fruits even seem to be growing faster now which is, of course, very exciting. I am beginning to question my current air exchange setup, however. I have been modeling it after the "dialed in" monotub tek which utilizes poly-fil and a fan for "forced" fresh air exchange (FFAE) because it was what I had used formerly.
Reishi seems to be a more forgiving species and it seems possible that it wouldn't necessarily do better with a constant fan running. Would I be better of just creating more holes in the tub to allow for sufficient air exchange and supplement with misting/manual fanning? Any advice would be appreciated, haha.

I gave the tubs a close inspection yesterday and discovered that both of them had spots of Trichoderma growing. I decided to harvest earlier than originally planned in order to salvage the fruits (which were slowing down anyway). The dry weight of the first flush was 243g.

I dunked the substrates under cold running water for about 15 minutes and then placed them back in the monotubs on their side this time à la Forrester's technique for producing conks on the second flush. The substrate appeared free of Trich. when I replaced them, but today I noticed it growing once more in the same areas.
I know Reishi is a vigorous species, but can it still fruit well while contaminated? Would it be worth it to let them continue or is that just a recipe for contaminating my whole grow area? I would just put them outside but it is below freezing here at night... Anyone ever dealt with this before?
