My bulk sub seems contammed, can you confirm?
    #13782966 - 01/13/11 10:58 PM (2 years, 5 months ago)



Tub was put into fruiting about 10 days ago, it knotted like crazy and has been pinning for days, I thought it might stall, or just be slow.  It was from rye bags from a sponsor, the coir prep I've used on three other tubs of b+ and had no problems with contams.

In the last 24 hours around the edges a bluish/greenish/greyish color has arrived, it is on the myc as well as the pins.  I have not had a contam before, but i have seen bluing and this seems to be different.

I took a lot of pics with different lighting so its easier to spot with the camera.

Your thoughts?

thanks!

Flood

The second pic is just the lighting I bet.

Now, that is (was) a great pinset and I see you drilled holes without anything to keep the humidity up.  That can be fine and dandy, but with a flush like that, you need to keep Rh high to support the growth.  What you have there sir, is a lot of aborts.  Don't worry, pick the black ones (if it can be done without taking out the good ones- black v. brown caps) and let the good ones go for it.  Flush and keep it going. 

In my experience a lot of aborts can cause superficial contams which can be removed with a bleached spoon, but try to avoid that by removing them.  Not to mention that the aborts are fun to eat as well.

Thanks for the input, there is a lot of metabolites on the edges, giving the yellowish appearance as i mist heavily twice daily, the areas of concern are greyish, and they almost appears as shadows, they are best seen in the last pic in the lower and upper left corners.

This tub design is an MSG or a mono/shotgun hybrid, it has worked excellently on 3 prior grows (different strain, and not quite as prolific pinsets but they each yielded over 1500g wet).  It allows for great evaporation and FAE.  The RH in the room has been a bit low lately at 10%, but i pay a lot of attention to my tubs and dont let them get too dry, if anything, i overmist (i think).

I've moved this tub to another room and will get the RH up to at least 30-40% and watch this tub for a couple days.  I dont mind losing the tub, but want to minimize risk of compromising my grow area, if it is bacterial, it wont hurt to give it some time.

Thanks again!

bacteria spread via air too dude. 

I think, however, you're fine here.  Keep an eye on it.
