Humidity at different stages, what's your take?
    #5519514 - 04/15/06 09:59 PM (17 years, 11 months ago)

So I'm reading up on rH levels during different stages for casings, and I've been coming across some different opinions. Some say 85, some say 90-91. Again, it also depends on the stage the casing is at. What I don't get, is how do all of you out there (especially those with marthas) maintains your rH? Do you raise it post casing and then lower it after pins form?

It seems impractical once you have multiple casings going (staggered at different stages) to be changing the humidity back and forth.

Do you normally keep your FC at a set rH or do you change it with stages?

i leave my coolmist on 24/7 and I have a 4 tier greenhouse ($30...great deal). there might be a little too much humidity inside mine. There is condensation forming on the sides. That is not supposed to happen around 90%. I'm not sure whether or not to let it run for 1/2 hr every two hrs or to just let it run 24/7 and keep the humidity real high. Whats worse...fluctuating RH or high RH?

I have been told that 80% humidity is fine for casings, i use a humidity controller i guess its a humidistat?

condensations has nothing to do with humidity it just shows there is a temperature difference. take a cold beer and stick it out in the summer. condensation coudl be super dry and you still get droplets.
just done use condensation as a measuring tool. anyhoo i find casing not to be so picky. i use teh same set i did for cakes except i fan more most of the time so imsure the rh stays lower. the more fae is good aswell haha. i got two birds stonned at once woo! i mean...

very true. i am sometimes a little careless with wording.
well considering that I am inside a room and don't live in antarctica right now nor is my fc a cold beer i think it is safe to use condensation as an indicator.

Not if you want to perfect your methods. We have tools for these things and I'm wanting to get better, so I need to be able to control my variables. Condensation isn't accurate.

Note: My original question still remains...

well solidcell...i just put my first casings into a martha. This is the first real grow I have done (once before in high school with cakes). I got alot of advice from Hippiechick. As you may know she uses a martha and gets fantastic results. She tells me to run the coolmist 24/7 which I have been doing. Mycelium is maturing nicely.
when I see pins I am going to try maybe one half hour on and two hours off by connecting the coolmist to a timer I bought for $10. There are more expensive ones out there if you want more control over your variables.

one of my casings will be pinning before the other two (hopefully) I will put this one on the bottom shelf once it starts. Yeah its crude but Im not planning on flooding the streets with these things.

I've heard for years to lower humidity for casings. I tested it and found higher humidity made for more pins. Not in every case but in most and with most strains.

I don't know about Mag's , but mine stays around 94-95 all the time.

I actually put mine on a timer. Half hour off every three hours. More so just to give the cool mists a break so they don't burn out as quick. :thumbup:

I can't complain about my results so I'm just letting it go the way it is. Great pin sets and not many aborts :grin:

I am going to set up a smaller green house for my Pans Cyans so I'll keep that one a little lower. I found if you stick some polyfil in the green house inlets, it will help lower the humidity :thumbup:

Wow 95? I hear so many different numbers on the subject. I constantly hear 85, but that a big difference. Is it that they can take a wide range, or is a certain number optimal? I have system right now where I can adjust the rH in increments of 1%, but I just don't know what would be the best to keep it at. And changing it for different stages isn't something I'm going to do.

I've heard between 85-92 for casings.

But if it's not broke, why fix it,lol :wink:

Ah perfect, I'm at 88% right now.  I guess it's time for a pictorial tek on my setup.  Thanks for the specs HippieChick, I love you :heart:.

So would you recommend that I bring it up from 88 to ninety-something?  I can get it on the dot, so I'll go with whatever number you guys throw at me :grin:.

Cakes or casings I shoot for 90-92% always great results never been any negatives as far as fruiting, pinning on the otherhand requires around 95-98% for best results consistantly.

So you drop your rH from 95-98 to 90-92 between stages, but what happens when you have casings staggered at different stages, will you give a pinning casing a lower rH or a fruiting casing too high of an rH to compensate for the other casings? It's always been on my mind how it's handled when doing staggered grows when dealing with marthas and greenhouses. Thanks for the replies guys.
