Bigred Posted September 7, 2012 Share Posted September 7, 2012 my favorite agar blend is Vegemite and ricemalt and yeast agar whats yours my recipe per 500ml 5 grams agar 4 grams Vegemite 3 grams karo or rice malt extract you could use honey to 1 or 2 grams of nutritional yeast this is optional but i always get better results if i do you can also add h202 a couple of ml's is all you need i like this one to because it goes 5,4,3,2 or 1 so its easy to remember would love to here of what others mix i do change from time to time but im not that far into preserving strains getting spores from the super market mushrooms takes a lot of patientsbut getting contams is part of the fun as well i got one that looks like genesis and it looks alive with little houses 3 Quote Link to comment Share on other sites More sharing options...

BentoSpawn Posted September 8, 2012 Share Posted September 8, 2012 What do you mean by "nutritional yeast" bigred ? Like bakers dry yeast ? Quote Link to comment Share on other sites More sharing options...
Psylo Posted September 8, 2012 Share Posted September 8, 2012 Dead yeast is an excellent nutrient (even for live yeast to feed off). It wouldn't matter if you used baker's yeast or brewing yeast. Baking yeast by the 'tin' would be the cheapest, a few bucks from the supermarketThe yeast will be dead as soon as you PC it, so it not going to grow in your agar.

Bigred Posted September 8, 2012 Author Share Posted September 8, 2012 bentospawn i get brewers yeast from my organic store it cost $12 a kilo its great stuff. With the test tubes psylo i get the glass ones with a lid for about a $1.50 each is the plastic just as good i also thought if you could use the little crack vials the are cheap as . I also used a bit of vegemite in my lc so will tell you guys how it goes Quote Link to comment Share on other sites More sharing options...
BentoSpawn Posted September 10, 2012 Share Posted September 10, 2012 (edited) I read bakers yeast is the better of the two when researching - i could be well be wrong on this however. Edited September 12, 2012 by BentoSpawn Quote Link to comment Share on other sites More sharing options...
Bigred Posted September 12, 2012 Author Share Posted September 12, 2012 (edited) I have used both i get les crap on the bottom and i get the same results i have been adding h202 and colloidal silver to my batch's and bacteria contams are now a thing of the past Edited September 13, 2012 by bigred82 1 Quote Link to comment Share on other sites More sharing options...
NSF Posted September 13, 2012 Share Posted September 13, 2012 Adding the silver and the h202 post cook? Once the temp of the agar has dropped a little but before it sets? Quote Link to comment Share on other sites More sharing options...
Bigred Posted September 13, 2012 Author Share Posted September 13, 2012 I add it just before i pour my plates also what would be the best blend for tube slants would it matter when you add your h202 could it go in before the pc. I am about to start doing slants for cold storage and would love a good recipe for slants . Quote Link to comment Share on other sites More sharing options...
NSF Posted September 14, 2012 Share Posted September 14, 2012 any temp above about 60 (i think) kills h202 and prevents it being effective at all. So you can add it before you PC but it will be rendered useless during the cooking. Instead of using h202 I like to pour my plates into take away PP sauce containers, 50ml odd, put the lids on, make a stack about 8 high and put those in a little PP bag, fold the bag over and PC (well I make a few of these stacks and PC altogether). So the only time they are exposed to contams is when I am putting tissue onto them inside my hood. So I go with the less vector theory, rather than defense theory. Defense theory being h202. 2 Quote Link to comment Share on other sites More sharing options...
Bigred Posted September 14, 2012 Author Share Posted September 14, 2012 i believe in the less vector theory to but i like to add a safeguard as i only have a hepa glove bag and i try to be as anal as i can when it comes to contams and i don't think its harms growth at all so its like a little insurance Quote Link to comment Share on other sites More sharing options...
BentoSpawn Posted September 16, 2012 Share Posted September 16, 2012 H2O2 will break down into H2O + O2 in the pressure cooker. The only advantage is having oxygen enriched slants and the small likely hood of maybe killing some organisms that could survive the PC.So its not neccisarily a complete waste of time, but definitely not needed.

Bigred Posted September 16, 2012 Author Share Posted September 16, 2012 another good one if you dont want much hassle is to get a tin of home brew like coopers ale and use 10 ml per 500ml and 9 grams of agar . My friend swears buy it he also just adds agar to light beer when he couldnt be fucked opening a tin Quote Link to comment Share on other sites More sharing options...
Bigred Posted March 12, 2014 Author Share Posted March 12, 2014 Thought i would bump this thread to see if anyone has s different agar blend Quote Link to comment Share on other sites More sharing options...
Electro Gypsy Posted March 12, 2014 Share Posted March 12, 2014 (edited) mostly depends on what i am doing. i guess if i actually had to measure it my most commonly used blend would be..500ml h2010g agar10g finely powdered millet2-3 table spoons pure vanilla extract1g reptile quality calciumjust about any grain will work. millet is just my preference. ime, everything fruits on it.when dealing with a wood lover i might use the correct wood tea instead of h20. increasing the calcium to 1.5gthis is also a straining recipe, but honestly, it only improves the cosmetics. if one desires a smoother agar.. mix everything but the agar and strain through a coffee filter. then add agar and sterilize.

spooge Posted March 13, 2014 Share Posted March 13, 2014 I use 3/4 agar 1/4 malt extract, dont make any of it, all from the shop.Nicen quick, even get little fruits in the jars i use as petries, pc 24 agar jars atta time, not the most economical way though does result in very clean cultures.

Electro Gypsy Posted March 13, 2014 Share Posted March 13, 2014 What's the vanilla for?old trick from an old friend. many fungi, especially psilocybe species find it to be an attractive nutrient source. some species may actually grow faster due to it, but i don't have any research to back it up. short of hobbiest posts. the original tek was written for liquid culture, but i have adapted it to agar as well. i actually like the liquid culture also. very clear. nice to work with and very simple. just pure vanilla extract and h2o. it was brilliant actually. the guy never got enough credit. 1 Quote Link to comment Share on other sites More sharing options...

theuserformallyknownasd00d Posted March 17, 2014 Share Posted March 17, 2014 Hey electro gypsy! Did you have a recipe/portions for the vanilla extract LC?! Quote Link to comment Share on other sites More sharing options...
Electro Gypsy Posted March 17, 2014 Share Posted March 17, 2014 Hey electro gypsy! Did you have a recipe/portions for the vanilla extract LC?!the original recipe is 500ml h2o with 3 tablespoons of vanilla extract.although, mycelium for the most part grew very fast in it, I ran into consistency issues. unknown if it was due to the recipe, but I am picky and more of a finesse style grower. I ended up at a leaner formula, not as fast, but long lived and worked very well.. consistently.1 teaspoon vanilla extract per 300ml h2o. I use about the same for agar.honestly I would suggest one strong and one weak lc so you can compare for yourself. maybe one in the middle too. lots of room to play in order to find the proper groove for what you are dealing with.

Bigred Posted March 17, 2014 Author Share Posted March 17, 2014 colloidal silver - this is interesting. please tell me more. I use a bottle of strong colloidal silver that i got from the states via mail I ad it to a lot of things even straw logsyou can make colloidal silver pretty easy . There is a lot more reasearch to be done in it and i have not got the time Quote Link to comment Share on other sites More sharing options...
