Heating a space
    #28542786 - 11/14/23 02:45 PM (2 months, 12 days ago)

Hi all , I'm new to the forum and new to shroom cultivation. 
I have done a little research and looking to get something started soon..

Please forgive me if this has been done time and time again. And feel free to link me up to older threads where applicable. 

Anyway, space is limited, and I plan to use some space at the top of a bedroom cupboard (double door)  . The space is about 1350mm wide x 600mm deep x 400mm high.

I plan to use battery powered LEDs above boxes on ceiling and storage tubs for my substrate.

The room that the cupboard is in ranges between 15 - 22c . So I would imagine the cupboard will be slightly cooler as it is not directly heated by the radiator in the room as it has the cupboard doors in between .

So this is the issue I have , Heating the cupboard up during the day (safely) without drying the substrate out . I don't want to run the heating all day every day as it would cost a fortune and I've heard heat mats are dangerous.

Also FAE worries me , as its in a compact space at the top of the cupboard. Although this is easily sorted as I can easily fit some sort of ventilation to come on couple of times a day when necessary.

Any input would be greatly appreciated,  many thanks

15C-22C sounds not too bad, I am growing in similar condition's atm, keep one of the doors cracked and see how much the LCDs will heat up the compartment as it will produce some warmth as well. What kind of grow are you thinking about?

Your main goal is to heat the air around the jars or tubs, not the jars or tubs themselves.

That would mean a heater nearby that isn't directly blowing on the tubs. Or a heat mat near them but not touching them. Or a heat lamp facing away with a thermostat to regulate the temperature.

If you can keep your temps above 18c or so, but ideally 21-24 you'll be a bit better off. If you go too low it'll stop or slow growth but won't kill the mycelium so don't stress if you can't.

As for fresh air, I'm having a hard time imagining the size of the cupboard or whatever but leaving the door cracked would be more than sufficient. You don't want air rushing past the tubs via fans.

I was thinking of following the broke boi tek video I found on YouTube by philly GT . then using monotubs, maybe 2. Filled with coco coir, vermiculite and gypsum .

I don't have a pressure cooker at the minute , and struggling with what one to buy in UK as none I can find seem to work at 15psi.

No PC needed.

You can also do all PC work at lower PSI levels. You just need to allow longer for sterilization. I use 12 psi and have no issues with my grain.

I'd really recommend you stay off YouTube when it comes to getting mycology information.

I've now got all the supplies for the 1st stage making the jars and colonising the jars .

I want to go with the water tub fruiting chamber method. The link provided doesn't actually have a part where it shows how to make the FC . can anyone provide a link for this please ? Many thanks

It's just a large box with water at the bottom and a way to lift the cakes off that water. So one of those oven grate things or even an upside down cup with your cake on top works fine.

:whathesaid:
1-2 inches of water and then lift the cakes out of it somehow. A cookie rack works great.

Right, quick question RE SAB. I will be sterilising my jars in the kitchen , my SAB has to be upstairs (2nd floor) , which means i have to carry them up 2 floors.

Now I know it's supposed to be as clean as possible for the inoculation part but in the tek it says to leave the foil off, and the lids have holes in anyway . So basically once it leaves the SAB  isn't it very likely for it to get contaminated regardless?

I'm a bit confused with how much difference the SAB is going to make in my scenario ?

Cheers ๐Ÿ‘Œ

As soon as you take the jars out of the SAB they are sterile but can be exposed to open air due to the dry verm layer at the top protecting the BRF. It is basically like having a filter on the top of your jar, that is why it is so important not to disturb it. Not a big deal to move them around the house though. 

Inoculating inside the SAB just helps keep the inoculation itself as sterile as possible.

hey i made this heating system for little closets years ago

https://www.shroomery.org/forums/showflat.php/Number/25861119

this was before "inkbirds" cane out though so that would be even easier

edit: see the last post on my thread there. i just realized someone already literally put it together.  easy peasy and safe.

It's quite astute of you to realize the SAB isn't doing all that much for PF tek inoculations.  You could get away with just doing it in open air.  The risk is that something could land on the needle between flaming it and doing the inoculation and contaminate the jar.  That's all you're trying to mitigate with the SAB.

SABs are more important and necessary when you're opening agar plates and grain jars etc.

While this looks like the perfect solution for me and I am quite eager to try using the TEK , it does worry me using it in my space I have in the top of the cupboard .

I understand now. Thanks. I will still use the SAB anyway as I have all the mats and might aswell utilise them .

I have everything I need for doing a BRF Tek , however I changed my mind since the yields were quite poor . So i decided I would buy the PC and use jars of grain then go grain to coco coir/verm substrate . However after more research , alot of people say to go spores to agar , then agar to grain then grain to substrate in monotubs .

My question,  I would like to skip the spore to agar as I'm already over 230 quid lighter in the pocket and itching to get going . But how likely am I to fail due to contamination because of using a spore syringe to inoculate my grain jars ?

I'd like to learn agar at some point but not just yet .

The overwhelming opinion here is no spore to grain no matter what.  Sure you might get lucky every once in a while but there are many many fails and shouts for help in this forum because of spores to grain.  Agar is the path to grain, without PF it.

Ahoy!
Is this a theoretical 'yeilds were quite poor' or have you done a PF Tek and decided it's not worth your while?
If the first option, you could always opt to run a load of BRF jars then shred them up before mixing into to bulk substrate in tubs.
IME it did yeild less than grain to bulk but low yeild is better than no yeild. Plus at least then you get some experience on the go!
:sporedrop:
I really enjoyed doing PF Tek to bulk for a while, got a nice supply of fruits to keep me going till I moved on to other methods, just food for thought.

If you're still struggling for a PC that will reach 15 psi in Blighty, I'm allegedly a UK guy as well and use this modest one.
Capacity wise, it is very small, so you will likely outgrow it- but it's still handy to get you going and hopefully won't break the bank.

I would NOT recommend shooting spores into a grain jar, I've had "success" in the early days noccing up grain bags but it's seemingly luck of the draw.
The bag WILL be bacterial to some degree, but it will likely still fruit.
Trying to blast spores into a jar through the SHIP, for example, seems like a bad time, really not ideal by any stretch of the imagination and certainly not endorsed by anyone who treats cultivation with care, IMO.

TLDR: OPTION A: perhaps running a deece amount of BRF jars and shredding them may suit you fine- this way there's no need for PC, as Way said, and if done with attention, high chance for success.

OR OPTION B: buy some prepoured agar plates to get you started for about 15 quid, go spore to agar to grain (which is really not intimidating once you get going in your SAB, it's a matter of care and attention) then get some wedges going in your grain jars!
Best of luck dude.

OK so I do actually have a Hawkins big boy pressure cooker now , MSS spore syringe,  monotubs , half quart jars with lids  , SAB , BRF, VERM, isopropyl bottle and sprayer. Sterile gloves .

I was saying about sub par yields simply because that's what I've read on here , and I just thought if I could, then I may as well bite the bullet and buy the PC and then be able to maximise yields by using grains . However I then read about the spore syringe being un sterile and to use Agar to grain.

So with regards to your reply , I'm understanding that you say I should still have a go at the PF tek so that I can dip my toe in the water then ?

So what is the difference between using the pf tek method as opposed to the spores to grain method ? As a total noob I would assume that if the unsterile part is the MSS then using a different tek would still be the same . What am I missing ?

Sorry for any stupid questions.  And thanks for the help

I went pf tek for first go for 2 reasons,
1 Birthing and casing is more forgiving as sab is a learned skill and a peice of equipment.  Bacteria has the upper hand durring shake.
2 Want some darn fruits! To do prints from to keep operating.
