What would you all recommend for a growing temp? My room is kind of cold, I think I might need to find a heating method. What would you recommend as a way to heat it as well?

I keep my terrarium in the 70's 73-74,if it gets cold in your room just use a light bulb to heat up your terrarium always works for me, or u could use a heating pad or a heating lamp,hope that helped

I would recommend 75 degrees to fruit.... 86 degrees to incubate, but have had many successes with temps that fluctuate wildly in the summer months.

From like close to 90 in my closet during the day to prolly the low 60's at night.

So long as you lower the co2 levels sufficiently and introduce the proper light to initiate the pinning cycle, it seems fruiting will still occur.

A dunk in the fridge to give a cold shock will surely be beneficial in the cases where you feel the fruiting temps might be a bit high from time to time(regularly reach an excess of 75 degrees).

A number of you recommend incubating and fruiting at temperatures in the mid to upper 80s. Fanaticus claims that, though these higher temperatures may cause faster fruiting, it does not necessarily create a better yeild. He also theorizes that the higher temperature may cause a loss of potency. I tend to take PFs thoughts into careful consideration. How does everyone else feel about this? I urge anyone who has thoughts on this to reply. I am trying to decide if is in my best interest to raise the temperature of my shroomroom or just leave it at room temperature. Thanks.

what are you at now?

By jim brown (Shrhobbyist) on Friday, October 26, 2001 - 10:04 am:

In the many times I've done this, the average temperature is usually around 75. I get good yields with this but sometimes they take a while, not too long, though. I have fruited at higher temps, usually what is room temperature in the summer and got good yields as well. I have never went out of my way to change the temperature. I am trying to figure out if that would be worth my while. My main question is, does anyone have any feelings on PFs theory about weaker mushrooms at higher temperatures?

ive heard that from other people as well, wouldnt surprise me

There is a difference between incubation temperatures and fruiting temperatures. Incubation is used for jars to speed up colonization and 84*F-86*F is the published temp to incubate (I like 86*F)

Once birthed into a chamber with humidification and fresh air the temp should be 75*F - 82*F for fruiting. Fruiting temps should be lower than incubation temps. The reason here is that incubation is a sterile process... Fruiting frequently involves open air. As temps climb in open air, especially stagnant open air, contams gain an edge and become much more competitive with fruiting shrooms. Dropping the temps some and increasing the airflow is the best defense against many common contams at this stage.

I just bought a 50watt fish tank heater and I have it in a large mason jar filled with water in the center of my birthing chamber. The water heater is set to 93degrees but the temp rarely goes above 75*F inside the chamber..... 75*F alright to birth at? or should I perhaps get a 100watt water heater....

By Nan (Nanook) on Sunday, October 28, 2001 - 09:04 pm:

75*F is fine

Shroom Glossary

By Brad (Raze) on Monday, December 17, 2001 - 10:27 pm:

My fruiting chamber is 68F on average. My incubator cost like 50 bones to build and it runs at 85F. Now, I cant afford another heater to get this thing to the 74-76 suggested, so how is this lower temp gonna impact the growth rate? I've had one thats been in there like six days and there's only one tiny pin at the bottom which I think has already aborted.
I was thinking since my incubator has higher temps, as well as humidity (I think my fruiting chamber is like 85-90% or something (cheap rH meter), where as the incubator is dripping so much I think its 100% that it might be a wise idea to innitiate fruiting in the incubator. Its already had a few days at low temp to help initiate fruiting, I think it just needs the extra hummidity and temp? What do you experts think? I really really really want shrooms for XMas

Why do some of you guys have humid incubators?

Maybee I am missing something here.

* Prevents Dry Jars

By Brad (Raze) on Monday, December 17, 2001 - 11:50 pm:

Its nothing that I planned. It simply is humid because of its design. The fish tank heater sits in a pool of water heating it to like 105F which radiates heat upwards. Where the jars are its a nice 85F.
The warmer water evaporates quicker, meaning more humidity.
I do think it has some advantage though, it stops the jars from drying out

By Mr. B (Argonaut) on Tuesday, December 18, 2001 - 12:06 am:

For an incubation chamber I have a large dishpan with an h20/h2o2 solution in it. I set the jars in it with the fish tank heater. I keep the water @ around 85deg(F) and that seems to be ok.
I lay a towel over it all to keep the light out.

By Brad (Raze) on Tuesday, December 18, 2001 - 04:31 am:

I like the light getting in a bit, helps it pin sooner

I was reading a post by onediadem *congrats by the way* and she was saying how she has kept her fruiting cakes at about 68-69F
Well right now I have a few cakes going and I also am keeping them at about 70ish degrees. Before I have always had my cakes at a constant 77F.
I am not seeing the exploding growth by the pins that I have normally seen. Is it safe to say that this is attributed to the difference in heat?

On another note: Could someone tell me some signs to look for that there may be to much CO2 buildup in my terrariums?

growth rates are very definitly affected by the temp, slowing markedly the lower you go.
too much co2 gives very long skinny shrooms, as they try to stretch up for fresh air.

Quote thanks thats what I was thinking altho sort of dreading it. I have a few terrariums and that would require 4-5 fish tank heaters and those are pricey little things... However I have massive pinset. Guess I won't be able to see about the C02 levels until the shrooms start to grow more. Thanks again for your input, its much appreciated.
