hi all, this is my first post in this forum. I'm from Indonesia and farming paddy straw mushroom also.
This is my spawn and the fresh fruit picture..
I hope i can get some inputs from all of you guys..




BJML, what is your base material for the substrate? it looks like a compost of some sort.
i am still having the dickens of a time with my volvariella growing. so far, the only thing that is causing me grief in the mushroom world.
i would be glad to get more in depth explanation from someone who actually has successfully done this. please don't leave out any details--temps, humidity, substrate moisture, etc,

thank you for sharing these super nice pictures. i have several jars of grain spawn waiting to do something with.

Hi Houdinihar...
The picture above is the final spawn which ready to spread on compost bed in a growing house.
My based compost materials for final spawn is depend on avalaibility of the subtrate in my local area, sometime i use paddy straw, sagoo waste or sugar leave. but i use paddy straw the most.
This Vv can grow at 28-32 C and humidity around 80-85 %. you will find coprinus grow well if the growing room's temp under 28, and the Vv's Micellium can't grow if the temp over the 32 deg.
We can't avoid the growth of other contaminant in growing room, but we paused it's growth periode (by using Pasteurisation)in order to give opportunity the Vv's micellium to grow.

I just wanted to point out that Paddy straw spawn can be any waste product due to the fact that it can utilize cellulose very very well. In case you were wondering why he is not using grain (Which help keep the rats and vermin away). The result of the harvest is very much dependent on the substrate makeup.

based on my experience since 1998, substrate make up is one of some factors to get good harvest in growing this mushroom Lipa.
I hope you can understand it, CMIIW...

By that I mean the type of substrate and the condition of it. I cannot elaborate on it. I am experimenting myself. All I have is information from experienced growers. So far important things are aeration during fruitbody induction, C/N ratio, flora, and temperature. They also like a PH of around 7- 8 as I am finding through papers and word of mouth and it is important that the temperature drops slightly for fruitbody formation and good development. When the temperature falls to early in the colonization phase fruitbody formation can occur causing smaller harvest due to lack of assimilation of nutrients.

Have you practice the maintenance process? without practising, i guarantee everyone can't really understand about the growing techniques.
Here in Indonesia, each area has different technique. But some of them interested to try my technique. Like i said, they have to follow my class in order to get good harvest result and deep understanding by practice on field, not just theory or word of mouth.

BJML,

1. Do you always pasteurize after the composting period, or do you sometimes spawn straight away?

2. I noticed in the 3rd picture [above] inside the growing room with all the young eggs that fluid is dripping down some of the strands of straw. Do you use any fans to move the air to prevent mold development-the reason I ask that is because the substrate looks very moist and you mentioned 80-85% humidity for the grow room? I did notice in a picture on your website that the groing room has a vent hole up near the top of the room but I did not notice any means of moving the air around.

Thanks for these newer pictures you/ve posted

1. i always pasteurize the media at 60-70 C for 6 hours then i spread the spawn. If today i do pasteurize, tomorrow i'll spread the spawn. you can see the timeline here,

2. the condition at the 3rd pict, temp 32 C, moist around 83 %, i use a door and windows for aeration. i open them if the temp reach 33 C above

as we know, best prize for Vv is at button stage or egg stage (for fresh and blanching usage). first day of harvesting for my spawn is 13-15 days after spreading the spawn and we can harvest them for 15-20 days. each spawn producer has different timeline. It depends on the strenght of spawn.

Here is paddy straw on agar

I'd say recovery over night is good. this is at 14 hours


I have them in a laundry basket layered with straw/coir mix using oat bran between layers w/spawn. the top is comprised of active coir and spawn. It is sitting on a seedling mat inside a perforated bag. As soon as the temperature starts to rise in the substrate and the mycelium is beginning to get dense I will remove the mat and wait for full colonization then induce fruiting.

I want to add!!! The mycelium of different strains can be significantly different as I am seeing as I start my collection. Hawaiian V.v. have denser mycelium than  those from the Philippines for instance



BJML..... Have you ever seen anyone use solar water heating to keep the beds heat up in less than ideal conditions. I am thinking of this as a means to keep the temperature up at night here since the temperature drops 10 degrees or so here at night. Running piping under the beds with solar heated water seems ideal in my situation and is very cost effective.

BJML, looks like some coprinus in the extreme bottom left rack. i have read that some people merely cut them off the straw and leave the rest as is. how do you handle that?

You said the temp was 32 C = 89.6 F. One of my problems is my outdoors temps has been close to 100 F for more than a month-so the temps in my garage are almost as bad. My temps are still low 90-'s to 100 during the day and 70's at night outside during this month of September. This seems to be well outside the normal range of growth for the Vv. My Tricholoma crassum and Calocybe indica are tolerating these higher temps just fine.
I do have a small incubator that can be used for maybe 2-4 of my filter bags to control my temps in the 90 degree range once the ambient temps drop enough.

I think you can try it to get ideal condition in your climate condition. I've never seen here in indonesia.

Hey BJML what pasteurization method are you using? Is it the hot water bathmethod or injected steam method, I am just begining again the experamints to try to figure out a highly productive way to grwow this mushroom with the materials available wich does not include rice straw at the moment ,    jEr

I had an isolation that looked like that but a little more buff in color I thought it was a mold though it almost looked like felt.  I was working off of a gill fragment from a store bought dried mushroom.  So my expectations where low.  At the time I could hardly find any pictures of the culture to reference.



Lipa,  If you use the solar idea and run lines under the bed, you could also have the hot water tanks sitting in the room acting like radiators.  So then not only are you raising the beds but the ambient air too.  Never seen it in a mushroom house but I seen it in greenhouses. 

Another idea is taking a  copper coil, and placing it in a compost bin.  Sinking the heat away from all that thermogenic microbial activity.  You could tie it in with the solar hot water to supplement some heat later in the night.
