    Hey guys, first post so sorry if I miss anything on here.

    I just finished building my first martha style fruiting chamber (PVC and dropcloth construction with a cool mist humidifier pumped in for FAE).

    Just started fruiting my first mushroom block in the chamber and the initial pins are looking strange. My last grow (shotgun fruiting chamber) - the mushrooms formed semi-normal looking caps, just smaller. This time the stems are thicker and the caps almost look inverted.

    Could this be a FAE issue?

    For reference:
    Room is between 92-97% humidity all the time controlled via inkbird humidity sensor. I don't know the air exchange rate of the humidifier but I've got it on the minimum mist setting hoping for a higher air to humidity increase ratio. Right now exhaust is just passive out bottom of tent. No intake/intake fan aside from humidifier. Growing in 70/30 oak sawdust and spent coffee grounds.

    So those mushrooms came out super funky- caps curled inwards I'm not sure that I took a photo of the final product, it was ugly.... FAE really didn't seem to be the issue, I think it was lighting. I added an exhaust fan just in case since it's still nowhere near scale and some strip LED lights and my next bag is looking a TON better (see pictures of martha and next bag).

    Thinking about completely rebuilding the martha soon. I want to switch from a hanging system to shelves- I figure at max using this footprint and shifting to shelves I can get ~25 bags going at once compared to the 15 with the hanging system. That should also take care of another issue I've had with mushrooms growing out the back &/or into the top of the bags.

    FYI- current config is:
    Lights on a timer 12/12
    Humidifier on humidistat controlled outlet. Targeting 94, turns on once it hits 92.
    Exhaust fan on same outlet. Turns on once humidity hits 97 (it takes the sensor a bit to register the change in humidity and it always overshoots creating a nice cycle).

    Cycle of humidifier/exhaust fan completes about every 4-5 minutes.

    Air intake is straight from AC vent, exhaust is outdoors.

    Thanks! This definitely seems like a rewarding hobby- one of those easy to start but impossible to master tasks.

    Right easy enough to start and screw everything up so you feel like you have to master it and do everything over again! I know it keeps my mind busy from the day to day stresses!

    K so I just wanted to finalize this convo with an update:
    Between adding LED string lights (cool 6500k lights) and a super low powered exhaust fan the issue seems to be resolved.
    The second flush from the sawdust block that I originally posted about has begun. Same strain/same block/ totally different results.
