    Hi there, I'm currently colonizing my first substrate and was wondering if I could get someone to identify the process at the moment. I've taken a picture of my substrate after 10 days. The grain spawn grew over 6 weeks.

    This is 5 quarts of grain spawn, with Damon's coconut coir tek.

    looking like nice rhizomorphic growth! The sides do look a lil dry but if its heavy when lifting don't worry looks like it may fruit soon but keep her colonizing for a bit longer... what you got goin in there and what are temps. You got loose top holes and tight top?

    I'm currently using a monotub design by the north spore group on youtube. The bottom is painted black and the sides are drilled with a 2 inch diameter hole, 6 in total.

    The fluff: I'm now worried it may be cobweb mould, would you say?

    I've haven't been keeping track of temp, humidity, or anything. There has been fae with the polyfil, and I've had it next to a baseboard heater, just going by feeling, it's been in my estimation between 75 and 80 degrees. I sprayed it a little just now, and because the top layer didnt seem fully colonized, I covered it, and placed the whole bin in a black garbage bag.

    I haven't opened the container for about 7 days prior to looking today. I was thinking about closing it for another 5.

    Oh and the substrate is about a brick of coconut coir, and 2 quarts of vermiculite. My grain spawn is 5 pounds of "wheat kernels" from the bulk barn, because I just could not find rye grain anywhere in my area.

    I sterilized the spawn in a pressure cooker at 15 psi, then inoculated 5 1 quart jars each with about 2 cc of golden teacher liquid culture.

    I got my culture over reddit from a reputable seller. I've got b+ amazonian, Ecuador, and one other.

    I would seal your fae holes it may be drying things out? Also if box feels like its 80 remember that mycelium creates heat as it colonizes so maybe put a towel in between or move a lil away, same issue here was trying on top of waterheater and sometimes got too hot.
    Wouldn't worry about fuzz like you said may just be dry surface so mycelium isn't rhizomorphic just more tometose i think its called...
    As for colonization you want holes closed and no light, also even tho bottom is painted you may still get sidepinning id recommend 2 layers of black garbage bags so sub pulls one layer and other stays in place so surface condition isn't perfect on sides... other than that your looking great for a first timer! Keep it up, plus never really hurts to fruit after pinning starts so 5 days may be a good idea

    Sleep nailed it ! May try Next time try placing in a heavy trash bag at time of spawning it speeds up colonization times since it keeps the co2 up and moisture stable. Don’t even peek for 10 to 14 days .I go 14 .I know it’s hard .lol And doesn't look like cobweb to me either .congrats you are doing good here’s to some chubby pins soon.

    Thanks for the encouragement and advice. I'm happy things are going so well. I sanitized the crap out of everything at every step. I can't wait to see some product, and I'll share the crop.

    I put the monotub in a couple garbage bags to seal the holes and to create darkness. They are going to colonize for a couple more days then I'll expose them to fresh air. For the golden teacher strain, how many times a day should I mist, and does it matter if the water is distilled or chlorinated?

    I like to see at least 100% colonization and prefer to see a couple pins u will end up with a better pinset for you patients .I Use bottled water to mist with Just to keep it clean .If u are going mist and fan 2 times a day is sufficient but make sure to fan it well to evap the mist off .Im starting to like the neglect tek tho just put a fan in the room on low pointing away from the tub mist only if it gets dry ..

    yea what he said... also 1st flushes usually don't need a mist and fan as the substrate should be at field capacity but after 1st flush you may need to start as the mushies are 90% water they will suck that shit dry! Keep it up your spot should work nice in the winter seasons!

    Hey Guys,

    Update with my 15 days of no light or air. I'm uploading some pictures; unfortunately it looks like there is some contamination, I'd like your opinion as to what I should do with the setup.

    The spotted white area in the photo is a green shade up close. I've been wearing a tshirt as a mask and covered my mouth and nose aswell. I'm wondering if I should toss the whole thing.

    It does look like the good old Trichoderma the first picture if you expose to some light it will most likely show green or you can swab with a qtip and if it comes off green its bad...id say if you have a spot set her out there the cold temps may help i have heard of very few cases when Trichoderma looses sorry bud keep trying how did you pasteurize your sub?
