So i took all my spent mushroom cakes and stuck them in the dirt of a big potted plant that i have. I grow catgrass in the bottom of the plant so it stays constantly moist and nice down there and ive noticed that the whole bottom is now coated with mycelium and smells like mushrooms. Is there any chance at all that this will ever go into fruiting again...? or do i basically just have a very moldy plant now? thanks for any info i really cant find info on fruiting mushrooms in this way or if it is at all possible thanks!

you might get some fruiting bodies but dont expect much.
in case you havent yet, be sure to take a spore print unless you have enough

Newfag here, I see that the List [Multiple eBooks about growing Marijuana] linked on the wiki is down. I am hoping some one here will provide some direction in the form of listing quality Resources and Books, relating to growing, specifically mushrooms and marijuana. a /crops/ starter pack if you will.

Are you sure? People say that they can become a disaster when their population gets bigger. And the higher temperature you have - the more active and numerous they get. It's 32C in my growbox rn. I've seen at least three of these buggers so far.

They have a normal low heat light bulb as their light rn, it's like an energy saver one, they're just small and I don't have any good lights yet, but why are the tips on the leaves yellowing, the lights not hot or anything, I used old compost garden soil and I water them a little once a day with tap water, so I hope thats enough info

You're overwatering and the plants are suffocating because of that. A plant that small doesn't need to be watered daily, once every two weeks should be enough.

It's my first time growing so i knew i would make mistakes.
I have this probleme, can you tell me what it is? I used Janeco light mix, i have a 400W lamp, the top of my plants are at 40cm of it, i extract 400 m3, im at 60 to 50% humidity.
I put 2L of water in 9L pots every 4-5 days (when i feel the dirt is dry), im at week 3 of bloom, i put 3mL of fertilizer per L of water every two watering. I add a PK booster 0-52-33 since last week every two watering too. Those traces appeared 3 weeks ago on one plant and now its on all my "Amnesia" plants (5 of them)
I can give you more details, more pictures if needed

If you don't have a meter and you set your water by color strips or drops, then you add humic and fulvic acids, those drive it way down really quickly the same way if you add silicate it will drive it way up.

In soil 6.2-6.5 is optimal, some strains are a lot more forgiving than others. The wrong ratio of cal/mag can mess things up too if it's way off. That leaf looks mottled like a potassium or phosphorous problem, it usually doesn't affect just half of the leaf though. Potassium, magnesium and sulfur take the biggest hit when you dip below 5.5 ph in soil.

YOU DIDN'T update on how your plants are doing. I say stop all fertilizer before you destroy them, they most definitely have had enough nutrients. All these companies try to sell you their over priced fertilizer but remember there's tons of nutrients already in the soil. It's ok to supplement a bit but too much is too much and can be more detrimental than too little nutrients. Also, your pots look kinda shallow, I believe in deep large pots.

Just wondering exactly how to inoculate these bags. It has a black injector port, with tape over it, do I peel back the tape, inject then put the tape back, or do I just inject through the tape and cover the hole with some of my own tape?

The instructions for the grow kit do not say anything about tape, and in the pictures it appears they have just stuck the needle through the tape and the port and not bothered to cover with more tape. I know some use the self healing injector ports, but I can't find any indication the one I has is self healing nor do I know what a self healing injector port is.

if its a self healing injection port, meaning that the material recloses when you withdraw the syringe, you dont have to bother with tape.

if in doubt just desinfect the port, inject and quickly conver with tape

I'm not trying to reinvent the wheel here I just had an idea for a project. We all know that keeping a fruiting chambers relative humidity above a certain point (people will argue about the exact number) is a major key to getting good flushes as well as fresh air exchange. My question is does the moisture level of the substrate cake you're using also have any kind of effect on fruiting? I ask because I came across this neat little "soil humidity sensor" that can interface with an arduino and I'm assuming a raspberry pi3 as well. I'm using the pi3 to semi automate a misting set up in my future fruiting chamber which will be using a RH sensor that interfaces with the pi3. Would sticking the soil humidity meter into a cake give me any benefit or would I just end up destroying a perfectly good cake? Again this is more just a neat little project idea I came up with.

any particular reason as to why youre using a raspberry pi? are you data logging via email or monitoring the chamber remotely? otherwise a microcontroller with a few relays will be enough be far

youre not talking about PF cakes are you? if so this whole set up will be a lot of effort for small scale returns.
some people love greenhouses, and they tend to love them back, but i only ever found them really useful compared to a monotub when running tests on newly isolated cubensis strains or fruiting pan. species

concerning the substrate humidity sensor, i dont think theres a lot to be gained since the relation between moisture content and fruiting formation is pretty obvious. just dunk after every flush. you can estimate the loss in water content by weighing fruiting bodies and watching the size reduction.

you should watch out with those digital RH sensors, some models are very unreliable above a certain threshold, youd definetely want to write a short program for recalibration against an analog hygrometer, and RH is really the only way to measure FAE seing as carbondioxide sensors arent that cheap, im not sure if the volatile organics could be used to measure stale air, but simply hooking up the fans to a time control should be enough since stamets gives good starting points on FAE frequency

Not sure if you'd gain anything from sticking it INSIDE the cake, that you couldn't get by either keeping the RH at a certain point. The cake is going to transport what it needs from the outside. That is where RH matters. Keep that in the zone and you should be fine. No need to poke around inside the cake.

Yield isn't the only factor. Plants grown under blurple lights are never as complex in the smell and taste department. I've grown with different types of blurples and while they do produce weed, I wouldn't use them if I was the only person smoking the stuff.

Yeah but for the most part users on this site aren't strict connensewers. Indoors all you need is a stable enviroment within an enclosed reflective space for your plants. With around 200w of Cfl, or HPS or Led, and a correct understanding of this plants feeding/watering schedules, come harvest time you should have a decent yield. On top of that you know exactly what went into the grow as far as ferts and pesticides go.

Came home from work and my new seedling has sprouted!

Strain is Dinafem's Blue Cheese. According to Dinafem, flowering time for Blue Cheese is 50 days, and should begin before the plant reaches 15 inches.

Grow medium is Fox Farm's Ocean Forest mixed 50/50 with perlite in a 4-gallon grow pot. Nutes are Fox Farms trio, Grow Big, Big Bloom, and Tiger Bloom. From what I understand, Ocean Forest is nutrient-rich enough that adding nutes isn't necessary until flowering begins.

I'll be vegging her under a 2 ft T5 with two 24-watt bulbs, and three 42 watt CFLs. At the moment only the T5 and one of the CFLs is on, the other two will come on once she gets a little bigger. For flower, I'll be using a 300 watt Mars Hydro LED. The LED arrived earlier today, never used one before. Despite being pretty cheap, construction is solid and all the lights work properly. There's no on/off switch, which I don't like, but it shouldn't be an issue.

I don't know whether I'll be scrogging this plant or mainlining.

I'm a newbie to shroom growing, and the bag tek seemed like a cheap and low risk starting point. For the most part it's worked well, it was easy to integrate into the grow room, prep and maintenance has been pretty easy, and it's still giving flushes. I've tripped almost daily for the past month and still have plenty of shrooms to last until the new bags start yielding. That said, will probably move on to jars and tubs once I get more experienced. The pack of six 1-pound bags cost $33 shipped so not a huge investment, a nice pressure cooker, agar solutions, laminar hood, ect are all on the wishlist for the future.

>>145569
Noticeably darker in color than the GT, not nearly as fluffy. Lots of yellow fluidy excretions. It may indeed be cobweb. Probably gonna toss the two PE's outside into the mulch pile.

i wouldnt toss them since at the moment theyre still well contained and some cubensis mycellium can be very whispy. a good way to identify cobweb without a magnifying glass is to measure the speed at which the mycellium spreads.
but the secretion sounds like cubensis fighting off some bacteria never had cobweb do that before. if you should have to toss it be sure not to carry too much spores back to your grow room.

and hey, congratulations on taking up such a nice hobby.
im still amazed that its possible to turn horseshit into such a great drug

and you really dont have to have a laminar flowhood eventhough it makes so much more comfortable, a big SAB is good enough for agar work and prepping inoculant syringes.

I've read this brand of jam jars in the picture are fine to use.Any one used them ? I have a 9ml syringe how many of these 370g jars could I fill up(will be using a mono tub afterwards)

Also read you can use pint drinking glass.just put a bit of tyvek over the top then wrap 3 layers of tin foil over the top.

you can use jar without a threading, but id recommend against it.
those glasses are good but you'd have a lot of marmelade. couldnt you order spawn bags over the internet? i really like to use bags for monotubs. any kind of jar that has a top with a popping mechanism will work

>add gypsum to your grain as you soak them
>i normally tape the holes up with medical pore tape, instead of tyvek, but thats only because i find it more convenient
>pressure cook for atleat 90min at 15psi, be careful not to have the glasses in direct contact with the bottom of the cooker.
>be sure to shake the syringe, dont mix the grains after injecting. the spores have to come in contact with eachother, shake at 30% percent colonization

id recommend against popcorn, i find it finicky to get the moisture right. popcorn often ends in bacterial contamination for me. if you could order online you can get it really cheap

id recommend getting the biggest PC you can afford as long as you know it runs at atleast 15psi. once youve chosen a PC you can calculate which jars would fill it in the most efficient way

im really high right now, please feel free to ask any questions

When your trichomes/crystals start to lean over like this, and when they're roughly half milky and half amber in color, is when it's done and ready to harvest.

A plant is ready for harvest when all the stigmas have turned orange/brown and receded into the calyxes which should be swollen. At this point the trichome heads will be milky and amber. If there are white stigmas left in the plant, it's more than likely not ready. Sometimes new white stigmas appear when the plant is under stress, for example if it's being flushed. Stigmas that appear at this point should be ignored.

Pictured plant is almost ready to be harvested. Pictured plant is not ready for harvest even though most of the stigmas on most of the buds were orange.

2-3 weeks ago i found a seed in my weed. I decided "why the hell not" . So i planted in a decent sized pot, with flower soil, fertilizer included. had it under a halogen light for the first 1 1/2 week. This week bought a Led grow light, pretty sexpensive. Does it look ok to be around 3 weeks old? Should i tranplant it not or wait. got no idea what the roots look like at this point, dont even know how to lift it all out of the pot.

thankfull for tips and stuff. And i know i want a female. but a male could work too. how many grams yield am i looking at if its a male? think in terms of cannabutter.

It's looking great now, right before the stage it's at now, like a week prior, is when you can start to feed it a complete veg formula and not have to worry about it being stunted. That plant in week 5 is what most should look like in week 4.

OK the burnt tips in this pic look like signs of micronutrient defiency; most likely Mg or Zn.

>>145213
the cupped leaves here are a sign the plant is trying to dissipate moisture from it's system.

>>145214
yellowing of the leaves starting a the bottom are a sign of nitro deficency, but the purpling of the stems indicates that it's not N you're lacking, but sulphur.

>>145215
The spotting and discoloration are another sign of micronute def. Looks like Mn.

Most likely what you need to do is add a moderate doase of a good broad-spectrum micronutrient; specifically one high in sulphur, manganese and zinc. Also, don't water quite so often. Water absorbs and retains heat much better than earth or matrix does and NorCal gets enough sun that constantly sopping roots become a breeding ground for pythia and root rot, both of which can produce that "burnt" look at the edges and tips of leaves. Add a little H2O2 to your nutrient solution when wattering for a few weeks to kill any root-pathogens that may have cropped up.

TL;DR

Don't neglect your micro regimin, invest in a hydometer, and detox your rootbed.

no fucking idea what I'm talking about but I saw 2 infographics about muhdeficiencies, the post

please stop spreading the micronutrient meme around, 95% of cases is something completely unrelated to micronutrients, and 4,95% you can fix those micronutrient related problems by fixing your pH/stopping salt build up

OP, looks like overwatering+mites+overall shitty feeding regime, but it probably doesn't matter anymore because I'm replying to a fucking 2 months old thread anyway

this board sucks man
