3014 strain (Pleurotus pulmonarius)
    #23347100 - 06/15/16 12:06 PM (7 years, 7 months ago)

I've been growing about 30-40 lbs per week of oysters, all mostly 1 cool weather strain. Now that its heating up, my production has shut down. I'm wondering if anybody has any experience with the 3014 strain of P. pulmonarius?

Ive been using lime-bath treatment of straw and adding 10% alfalfa pellets (rehydrated with boiling water) at spawning. Its been working very well and getting good, consistent yields until the weather warmed up...we were pulling about 20-25 lbs on the first flush from 26.6 lbs (dry weight) straw + alfalfa. .....now nothing.

any experience would be good to hear about.

It is 8801 (and a little JS2) that I have in there now. Both P. ostreatus, both supposedly cool weather strains. All was good until we had a week or so of hot (around 90 outside) weather.

I would say the temps in the fc got into the low to mid 80s. I have a temp probe in there, but havent been monitoring it.... I know I should have, but anyway. Its dropped back down now to the mid 70s which I know is still a little high for cool weather stuff.

I pulled 6 bags out that were supposed to be fruiting and put them in a cold room/fridge for a couple of days, then back in the fc 3 days ago and still nothing.

I am wondering if I should leave them in the cold until I see pins.

I am starting 3014 today, but I've never grown it so I am hoping for tolerance to the lime bath and quick fruiting. I dont want to miss any more market days when people are coming specifically to find me.

I started some pinks and yellows too, so we'll see. I'm hoping 3014 does well.

I grow a lot of a Mycelia strain which is likely the same.

Great flavour, very wide temp range, I now grow it all year round. Good flavour and keeps the same as Greys.

Yield is lower than greys but you do tend to get most of it on the first flush



Grey in the summer and a deep chocolate brown in the winter.

They are ready to pick when they look like "past it" greys.

Grow sheet... 3014

Amycel 3014 Pleurotus pulmonarius
Substrate and
Pasteurization
Spawning
Flushing
Cropping
7•••
Substrate: This strain has a broad range of acceptance of
different substrates •.Typical materials that can be used include
chopped wheat straw, hardwood sawdusts, cottonseed hulls,
sugar cane bagasse, paper mill sludge, and other agricultural
waste byproducts. Limestone or calcium carbonate should be
added to achieve a pH after pasteurization between 6.8 and
7.2. Depending on the material used, nitrogen content of the
substrate after pasteurization should be between 0.6% and 1.3%.
Spawning: Spawning the substrate can take place after
the substrate has cooled to between 25°C and 30°C (75°F - 85°F).
Spawning rates will vary between 2% and 4% of the wet weight
of the substrate.
Supplementation: 3014 responds well to the use of delayed
release supplementation. Care should be taken to avoid excessive
temperatures during spawn run when using supplementation.
Temperature: 3014 will fruit at a very wide range of
temperatures, 10°C to 28°C (50°F- 80°F)with the optimum range
between lrc and 20°C (63°F - 70°F).
Humidity: During the formation of the primordia, relative
humidity should be maintained at 95% to 100%.
Cropping should occur while the leading edge of the cap
remains flat. Overly mature product is characterized by an
upward curling of the outer margin of the cap.
Temperatures: Cropping temperatures should be
maintained between 18°C to 24°C (65°F - 75°F).
Moisture content will range between 70% and 80%.
Pasteurization: Typically pasteurization is done either by injection of
live steam into a pasteurization room or by submerging the substrate in
a hot water bath. If the live steam method is used, the minimum
recommended time is 2 hours at 70°C - 75°C (160°F - 170°F). If the hot
water bath method is used, temperatures should be between 70°C 80°
C (160°F - 180°F) for at least one hour.
Temperature: Average spawn run temperatures should range
between 25°C and 30°C (75°F - 85°F) and should not exceed
33°C (92°F). Spawn runs normally take between ten to eighteen days,
depending upon spawn rate and temperature.
Relative Humidity and Carbon Dioxide: Relative humidity should
be maintained between 90-100%.CO, should be between 5,000and 15,000
ppm.
Carbon Dioxide Requirements: CO, should be lowered to 600 to
1,000 ppm. Ventilation should increase to 5-7 fresh air exchanges each
hour.
Light Requirements: Light intensity should be lowered to 1,000-1,500
lux at least 8 hours each day.
Humidity: Relative humidity should be kept between 85% to 90%.
Carbon Dioxide Requirements: CO, should be maintained between
600 to 1,000 ppm. Ventilation should be maintained with 5-7 fresh air
exchanges each hour.

I had Amycel email me the grow sheets..


AMYCEL
3015
Pleurotus
ostreatus
{Picture of Mushroom}
Marketing Characteristics:
Amycel3015 Pleurotus ostreatus produces a whitish gray to blue gray fruiting body.
Depending on which growing practice is used, it will form large mushroom clusters or
smaller, single mushrooms.
This strain is a cap tongue shaped, maturing to a shell shaped form 5-15 cm (2-6 in) in
diameter, with even or wavy margins, and an off-centered stipe
Note: The following are recommendations for growing Amycel's 3015, Pleurotus ostreatw
Due to the many variables involved in growing mushrooms, Amycel makes no
guarantees regarding these recommendations.
General Characteristics
Amycel's 3015 is a fast growing, self fruiting and high yielding, Pleurotus ostreatus that
adapts readily to many different types of growing conditions and substrates. Though in
nature wild strains are numerous in the fall and early winter. Amycel' s 3015 under
controlled environments, is a year round crop.
Substrate and Pasteurization
Substrate: This strain accepts a broad range of substrates. Typical materials can be
chopped or whole wheat straw, hardwood sawdust, cottonseed hulls, sugar cane bagasse,
paper mill sludge, and other agricultural waste by products. After pasteurization, limestone
or calcium carbonate should be added to achieve a pH 6.8 and 7.2. Depending on the
material used, nitrogen content of the substrate after pasteurization should be between 0.6%
and 1.3%, with moisture between 70% and 80%.
Pasteurization: Typically pasteurization is done either by injection of live steam for a
minimum of2 hours at 70° - 75° C (160°F - 170°F) or by submerging the substrate in a hot
water bath for 1 hour 70° - 80° C (160°F - 170°F).
Spawning
Spawning should take place after the substrate has cooled to between 25°C and 30°C (75°F85°
F), with rates between 2% and 4% of the wet weight of the substrate.
Those new Amycel's 3015 are encouraged to use the higher rates until becoming more
experienced with the strain.
Temperature: 25°C and 30°C (75°F-80°F) not to exceed 33°C (92°F). Spawn runs normall)
takes between 7 to 14 days. Thermal death occurs above lO4°F/48 hrs
Relative Humidity: 90-100%
Carbon Dioxide: 15,000 and 20,000 ppm or 15% to 20% by volume.
Flushing: Amycel's 3015 will fruit at a very wide range of temperatures, lOoe to 28°C
(50°F - 80°F) with the optimum range between 13°C and 16°C (55°F - 60°F).
Humidity: 95% to 100% during for formation of the primordia.
Carbon Dioxide: 600 PPM - ventilate to a minimum of 4 rresh air exchanges each hour.
Light Requirements: 2,000 lux/hr - 12 hr/day ..
Watering: Mist 1 - 2 times/day
2
Cropping: Crop while the leading edge of the cap flat. Overly mature product is
characterized by an upward curling of the outer margin of the cap.
Humidity: 85% to 92%.
Carbon Dioxide: Below 600 ppm - ventilate with a minimum 4-6 fresh air exchanges eac
hour.
Watering: Mist regularly to prevent cap splitting and to keep resting pinheads viable.
Light: 2,000 lux/hr for 12 hr/day ..
Flush Intervals: Approximately every 10 days.
NOTE: Workers are encouraged to wear masks whenever working around spore
producing mushrooms. Spores may cause allergic reactions in some workers.

Im confused, it seems that 2015 has a wider range than 2014.. Why was i under the assumption that 2014 is a warmer weather oyster?

I know what you mean Gr0wer. I think spec sheets are often not a good representation of what a strain can do, just a starting point.

Thats why I am more interested in peoples experience.... but I guess mostly from people who pay attention and keep good records

GrOwer..

I ask the lady at Amycel, on the phone if 3014 is for warmer temperatures than the 3015 and she said yes the 3014 is for warmer conditions. But I got the feeling she wasn't the one to get technical information from so I had her email me their info on the two products..

I suggest to give them a call and hope you talk with a tech person..

Amycels pretty useless for cultivation info.  Even if you got a lab tech on the phone they are still just making spawn, not cultivating.  I can't get 3014 spawn they only sell it as grow bags full of cotton seed hulls.

Dang, she didn't tell me it was cotton seed hulls. Well at least I can make masters with the culture.

I could be wrong but that's what I was told a few years ago.  You could still probably use it as spawn.

I just got the spawn from them. 25 lbs on millet. it was a little over $30 shipped and it got to me in 2 days, but you have to send them a check and they have to get it before they will process your order.

If you want to buy a lot you can set up 30 day payment terms with them.

I've inoculated my first 95 pounds (wet) of alfalfa supplemented straw (lime bath)

I'll let you know how it goes.
