Spawnmate IISE

Many of you know that I am beginning commercial production of Eryngii as my primary crop. I'm also going to be growing yellow oyster and pompom. Unfortunately, supplies are coming in faster than I can build (I'm locked out of my garage too, gf broke my key). I bought spawn from Mushroom Harvest, if you are east of the Mississippi, I highly recommend them. Until I feel comfortable being Lab Manager and Growroom Manager, I will buy all my spawn from them.
I used one extra bag of sawdust spawn on some granulated corncob that I had laying around. When I started, I forgot about my spawnmate IISE, so the first tray was unsupplemented. After that, I added some spawnmate, without weighing it and mixed it in. Here are pictures on day four. These trays are just sitting outside under a canopy, inside a box with perlite. The box is covered by a wet towel.

The top one is supplemented with Spawnmate IISE, the bottom is not.
It's hard to tell from the pics, but I will try to explain.
The top one has spots of dense mycelial growth and connective mycelium, pretty much covering the top of the tray.
The bottom one has only just leaped off, each growth spot is only an inch in diameter and there is no visible hyphae connecting the points of inoculation.
This spawnmate stuff REALLY works well so far. It will obviously shorten colonization time considerably. We will see in the future how much it helps boost yield.

Well, they look pretty similar at this point, but the real value of Spawnmate shows in the subsequent flushes. Flushes 2 and 3 are significantly increased...so which is the supplemented tub?
The supplement I use is T6 from Mushroom Central in Kennett Square PA. I think there is a new T7 and I'd like to try that. I think the T-series is created to help combat green molds as well as to stimulate higher yields. Just something to keep in mind.
Are you buying sawdust or grain spawn?
oh yeah. and what species is that that you have growing there? Eryngii?
I saw this the other day and thought of you -http://www.mushroombusiness.com/magazine_index/003_february_2004/cultivating_king_oyster_mushrooms.php
I just got Peter Oei's book after many many years of putting it off. The 2003 edition is really great, probably even better than Stamets books quite honestly...especially for those looking at mushroom farming as a business. There are feasibility studies, business plan/farming planning equations (that you won't find in Business Plan Pro cuz I know we both have that!)
I'd highly recommend it. The only place I could find a new copy in the USA (after searching every used book site I know). The Mushroom People sell it for $50. For you man, I would really recommend this book, it has a lot of awesome info and hit points I'd never considered before. Mind you I'm only 90+ pages into the book so far. I just got it in the mail Friday.

Hey bro! These are eryngii.
The pictures do not do justice. I will have to take pictures with the plastic off. The one on the top is supplemented and the one on the bottom is not. Both were spawned with the same strain of eryngii sawdust spawn. This is not my commercial plan - for my commercial crop I plan to use 10% grain and 10% sawdust and use pasteurized wheat straw as a substrate. This is almost as Stamets laid out in GGMM except he calls for a 40% inoculation rate on straw, 20% sawdust and 20% grain. If my results are not satisfactory, I will try doubling the spawn rate before changing substrates. If I change substrates I might even end up using crushed corncob, but it is more expensive than straw. I am too small to buy in bulk, so I would have to pay $4 for 30lbs. I just talked to a major distributor of corncob, he informed me Pennsylvania used corncob, but switched to cottonseed hulls because of shipping costs.
I would like to try out that other supplement or make my own. I really wanted to try Spawnmate PG Natural because it is their organic product. When I spoke to my local rep, she talked me out of PG Natural and onto IISE because 1) IISE is designed for straw grown mushrooms, 2) PG Natural is NOT certified organic in my state. The basic premise of delayed release supplements is that they are hydrophobic. IISE uses formaldehyde to accomplish this. I'm not very keen on this. I think I could take soy meal or soy flour and coat it in beeswax or another natural wax or paraffin. Then I would grind it back into a powder.
That was a good read by the way. I'm a little confused on the way they express yield. I was at a farm in Wisconsin a few months back and I flipped through Peter Oei's book. It is much more informative than Stamets books. Clearly he designed his book for someone with plenty of experience, whereas Stamets books are designed for the novice to expert.

Peter Oei describes three ways of expressing yields in his book. I just saw them yesterday, but I think they were- Oven dried substrate weight to oven dried mushroom weight - this he says is most accurate, but hardest to do BE - as usual, and then Fresh weight substrate (pre-moistened) to fresh mushrooms, so he may be doing his yield calculations in some odd way there, I'll have to re-read the article...
I actually flipped through a 1996 edition at Florida Atlantic University last week. The book was so good, I immediately searched out a copy of the 2003.
Also, as far as an organic supplement -have you seen the method of making delayed-release supplements from flax/rape/mustard seeds? Here is what BlueHelix had to say over at Mycotopia
Quote:
Notice that the three top oil-rich seeds with delayed nutrient release properties of the greatest yield enhancement were, from most to least, flax, rape, and Brassica juncea (brown mustard). All three, ironically, enhanced yield more than the SpawnMate itself.
I have tried flax seed. While it has quite a potential from the report, it also has a very strong gumming property when exposed to steam or hot water that closes off gas exchange to the substrate core even in very tiny amounts. Rape, on the other hand, is a great, inexpensive choice according to the folks I know online who've tried it - if you can find it; I can't find it.
The brown mustard, which is often called black mustard although true black mustard (Brassica Nigra) does exist, is the third one. Technically I believe I have brown mustard and should be referring to it as such, although like I said the name "black mustard" is often often used to refer to brown mustard too. It can be found at many Halal meat stores for super cheap like a few dollars a pound; and for the record, no, I am not a Muslim but do know about these stores. I tried this seed and found it very compatible because is very tiny and doesn't gum the mix up.
In reality my use of the seed before pressure cooking is probably not totally comparable to the use during spawning, as in this report, because the pressure cooking releases the oils somewhat with the hot steam. Indeed, the whole point of adding the seeds at spawning is to create a DELAYED release mechanism to improve the later yields. Still, though, even the addition of a small amount of straight liquid oil or oil-bearing seed like sunflower (listed as the sixth most beneficial above) improves the fruiting potential of any substrate as it rounds the nutritional matrix. I'd rather add oil in the form of a seed rather than a shot of liquid oil. That's just me. Moreover, I've had the best yields possible using brown mustard, and while I can't say it's the reason, I can say it doesn't hurt anything for sure and I have it around.
From here; http://forums.mycotopia.net/wild-birdseed-teks/5951-panaeolus-copelandia-cyanescens-goliath-liquid-culture-fruiting.html
I can't find the report he's talking about, but it is the one I am referring to. I think it is archived here somewhere, because I believe I originally saw it here...

I'll be testing Spawnmate IISE as well... I'll let you know of my results, May be a few months.

I played the part of a concerned potential customer, I asked lots of questions and eventually was offered a sample. I was told they could pull a sample off the product line. I was very surprised when a 50lb bag showed up. For purchasing it costs, IIRC, .56/lb.

Does that mean that you would not use that method? I'm sure you can at least contact the patent holder and see what they would want to allow you to use their patented method in your small scale farm.
I would imagine that if you weren't selling it to anyone it probably wouldn't be a big deal. I could be totally wrong and cost you your farm with that sentence though .
sssssshhhhhhhh
