Damping Off

yea, it seems it will kill the bacteria and mycelium, Im going to try on a couple males, deff not going to dump it in my fem buckets tho. A spray is prob the best application for the leaves I would imagine.

what is RH do u mean "PH.??" just asking

Relative Humidity..........

OK so I'm still having trouble with this. Have a couple that are limping along but this is what I mean. About 2 weeks ago I moved them out from under my t5 to my 400w mh. My humidity meter is broken, but the temp is around 80 degrees. Any thoughts? It looks to me like a classic case of overwatering, but I assure you guys that isn't the case. Also, when I transplanted a few of the bigger ones into the grow bags, I saw they had a nice, healthy root system.

I think they look very hungry to be honest with ya. Theres not enough nutrients for that vigorous of a root structure. Go 1/3 strength on the bigger on and 1/4 on smaller. If your into the AACT brewing, then I would go that route to feed/water, especially since you have a questionable luck with the R. Solani

Possible with the bigger plants, but been having this problem since they were seedlings.

I was reading in another thread that when the humidity gets too low, it signals the plant to retain water, which causes them to have the symptoms of overwatering. It seems like that would make sense. Anyone verify that? I would think it would cause the plant to lose water through excessive transpiration.

Sonar,
An overwatered plant generally has drooping yellowing leaves...sometimes cupped downward. A plant in low humidity, in an effort to limit transpiration, will try and fold the leaves...but upward.

A plant that has transpired away much of it's water (underwatered) will droop and look a little like an overwatered plant. But all you have to do is feel the soil to tell the difference.

You need to maintain humidity at a fairly high level for seedlings. Maybe 60% to 80%.

So you thinkingit could be a humidity issue? When I first started growing mushroom I did cakes and used what they call a shotgun terrarium. Basically a clear tote full of small holes with a thick layer of moist perlite in the bottom. The wet perlite keeps the humidity inthe tote high. I think I'm going to get some wet perlite and put it in some trays all around the tent. Hopefully that can raise the humidity a bit until I can get a humidifier or something and come up with a better plan. This is so frustrating. I never had an issue like this before, although I don't remember starting plants ever this time of the year.

Sonar, I mentioned earlier on this thread that I had a similar issue while growing in the winter in Iowa. Your shotgun chamber idea sounds good (I used to grow shrooms too) though anything that will add humidity. I just used lots of trays of water around seedlings to create a little micro climate.

Try incorporating all the tips you got. Increase RH, maybe use a little antifungal at the base of stem. Moving air, lights not too close and not too hot.
Good luck,
