Bulk Grow - PROBLEM with PINS ***Pics***
    #2987729 - 08/10/04 08:23 PM (12 years, 3 months ago)

PROBLEM - 4 days since pinset and growth is very poor. Please help.

This bulk grow setup is as follows:
- strain is B+
- finch seed spawned to pasteurized wheat straw
- substrate depth is between 3 to 4"
- 50/50+ peat-verm casing depth is 3/4"
- humidity - rH 95+, misted once a day
- CO2 - air exchange is once a day by use of a vacuum
- light - regular indirect daylight

you need more air exchange
add some holes to the side of your container
plug with polyfill
if you can't fan some (a lot) more

But if I increase the air exchange (more fanning), aren't I disturbing the humidity level more than I am now, thus resulting in more stunted growth?

My main worry is:

Could the amount of spawn and substrate depth be the cause? I used 3 cups of spawn for a minimum substrate depth of 3", and the area of the container is 1.8 square feet.

I agree. Your humidity will not chanfe much at all, especially if you add the polyfill. Air exchange is crucial for pinning. You definitely need to fan more than once a day. Good luck!! :grin:

i like the "vacuum" tek........not sure it does any good though.......is it an orek?

by the way RH appears to be a little high @ 95% for cases.........

but at least you can spell "pastuerize" louis would be happy!

peace

So what do you suggest I do now with the undergrown buttons? Will they grow if I increase fanning?

Also, can you put my worries at ease by ruling out the substrate depth and spawn amount as the cause?

IMO I think think your depth is not the problem, my foaf has had similar before and done just fine. Also, your spawn isn't the prob either. In professional cultivation, they sometimes go as low as a 1:100 ratio for spawn.

So what am I able to salvage by stepping up the fanning now?

Question:

Are you supposed to fan that much during the pinning initiation stage as well, or just after pinset? Since I was achieving an abundant pinset I assumed fanning once a day was sufficient to maintain CO2 levels during growth.

salvage is a tough word........

I agree with Magash(and staments) that 1-3 air exchanges per hour is optimal.......

give the mushies O2.......

by the way........I seriouly doubt that you were using a vacuum.......

there are so many other simpler ways.........

Future flushes.

Put a cool mist on a timer. That will exchange the air fast and won't fuck with humidity much

You don't want co2 during pinning (the drop in co2 levels are a pinning trigger BTW), and you do not want to maintain co2 during growth you want transpiration which aids in larger flushes AND larger shrooms. Oh the possibilities!!!!

I was using a vacuum to suck out the CO2. I thought it would be a good method to exchange the air (by convection), and reduce chances for contams (since you are not fanning open air in).

Thanks for the input.

So fanning many times a day to trigger pinset won't affect the humidity? How quickly does a humidity rebuild once you close the lid after fanning?

Wouldn't I have to get an air pump along with the cool mist humidifier? I'm not into extra costs right now, so I guess I'll stick with fanning.
