My humidity problem
    #7485066 - 10/04/07 01:55 PM (16 years, 3 months ago)

Im using a 64 qt/61 L tub with 2' of perlite but my humidity levels only reach 90% tops.Its sealed tight at the top and theres no holes in the tub.
Is it because the tub is to big?
Not enough perlite for that size tub?
suggestions?

Use as small a tub as will still work and you will be fine. Typically, 90-99% humidity will work, there is no need as far as I know to be obsessed with 99% at all costs.

Perlite is nasty, use open water or damp vermiculite, perlite should be banned!

I have never had any issues using open water at the bottom of a tub, or vermiculite, perlite is dirty, abrasive, and dangerous to breath, it is the MOST dangerous and nasty humidity regulator there is!

Jamaican.... I wouldn't place too much stock in what Cpt Cube said! Perlite, is in fact, a great way to raise RH in your FC. Yes, you don't want to breathe it in, but that's one of the reasons you rinse it off real well. Your mushrooms will grow better if your RH is closer to 99%. They will grow at lower levels of say 90% or so, but 99% is optimal. Why wouldn't you want to strive for optimal conditions?

I also have three 64qt Sterilite containers as my FC's, lined with 4-5" of well drained, damp perlite. If you are using perlite, you DO NOT want standing water in the bottom of your FC. That defeats the purpose of the perlite! The perlite has a large surface area with all kinds of nooks and crannies, and the air flowing through your damp perlite raises your RH. So, I would add more perlite, but I would also drill holes in all six sides of your FC, so it would be a shotgun FC. Have you seen RR's videos on Youtube? If not, watch all four of them. He explains the whole PF Tek process of making brf/verm jars. The videos are the actual footage from his 2dvd set. Here's the link...

http://youtube.com/results?search_query=let%27s+grow+mushrooms&search=Search

I'm not sure what captain cube meant by using damp verm? I've never heard of using damp verm to raise your RH. I have heard of using moist verm as a bottom layer of a casing. The only verm you need in your FC, should be on the outside of your cakes when you roll them in verm after you have dunked them for 24hrs!

The shotgun FC, involves drilling 1/4" holes in all six sides of your plastic bin. Then filling the bottom with 4-5" of well drained, damp perlite. The cakes should be place on a piece of alum foil on top of the perlite. Make sure you fan about 4-6 times a day. This set up works great. I've used it on all my grows, for cakes and casings and haven't had any problems wiht RH! Just make sure ang get a decent analog hygrometer to check your RH.

So....

1. Don't listen to Captain Cube. He's got some misinformation there.
2. Don't use standing water in your FC!!! Unless your making a Poor Man's Pod (PMP). The PMP has bubble wands in the bottom, lava rocks covering the bubble wands, water added into bottom to where it's about 1.5-2" below top surface of lava rocks, air pump on outside with hoses going through two holes to the bubble wands, and two more holes at the top of the bin for air exchange.
3. Keep your 64qt plastic bin. It's just fine!
4. Watch the RR videos on Youtube
5. Study, Read, and post back if you have more questions..

I'm not trying to be a prick, but you have to be careful on whose advice you follow. Some people say a lot of things but don't really know what they're talking about. I wouldn't be too inclined to take advice from someone with 29 posts and has been a member for 2 weeks. I don't think he was deliberately trying to tell you wrong. He just misinformed you! Good luck...

One more thing, open water in the bottom of your FC is just asking for contams! Like I said, the PMP is really the only time you need water in the bottom of your FC, bc that setup is designed to have it.

Fair enough man, but really, just cause I registered 2 weeks ago does not mean my experience is limited to 2 weeks.

Further, one should refrain from personal attacks on credibility, there are literally THOUSANDS of posts on the Shroomery with less than orthodox teks in them, anecdotally yes, but surely not EVERY author of those posts is a complete idiot.

For every WRITTEN IN STONE tek you can name, there is an example of the opposite working well.

My foaf used the standing water/damp vermiculite tek all through his BRF cake days, with fantastic results.

In fact, he reports that one bin, with NO FAE at all, ZERO, with standing water on the bottom, BRF cakes sitting on damp vermiculite in a smaller pan, with five 1/2 pint cakes yielded a total of 60 grams wet, first flush, 75 grams wet 2nd flush, and 2 subsequent flushes of less, but similar weight. Furthermore, the jars were colonized and fruited at the same room temp, no heating whatsoever, using just ambient room light from a south facing window. One fruit was 8 inches long and 25 grams, harvested well before veil tearing.

How many rules does that violate Mr. police man?

Again, NO FAE, no fanning even, no perlite, no dunk, no roll, no light bulbs, no heater, no temp drop, just a pan with damp vermiculite serving as a bed for the cakes to sit on, sitting in a larger bin with open water.

I am NOT suggesting these conditions are optimal, or even advised, merely that they work, or that they worked well for my foaf.

Again, I respect your opinion, you should respect others.

Try a tek before you lambaste it, you will be surprised how wide an array of teks will yield good results.

Check out the MSDS data sheets on perlite if you think I am wrong. Maybe research before you slander next time.

http://www.perlite.co.nz/safety-pumice.htm

Here is a perlite Toxicology: Inhaling crystalline silica-containing dust can aggravate upper respiratory conditions such as asthma or emphysema. Long term exposure to mineral dust which contains crystalline silica can cause the lung disease silicosis.

A recent review by the International Agency for Research into Cancer of public literature on the carcinogenic risk of silica and silicates has concluded that there is limited evidence for the carcinogenicity of crystalline silica to humans'.

http://www.pennperlite.com/msds.html


Caution and Warning: Keep Out of Reach of Children. Do Not Take Internally. Dust created while pouring into paint may cause eye, nose, throat or upper respiratory irritation. Long term breathing of large amounts of mica or talc may cause lung disease. This product contains small amounts of naturally occurring Crystalline Silica that has been identified by the International Agency for Research on Cancer as a Carcinogen. Emergency Product Safety Information: 800-821-7352

This product may contain crystalline silica (less than 0. 1% - see section II). OSHA considers Perlite a nuisance dust and recommends a PEL of 5 mg/m3 TWA respirable dust. Inhalation over long periods of high amounts of any nuisance dust may overload lung clearance mechanism and make the lungs more vulnerable to respiratory disease.

http://www.norcalperlite.com/MSDS.htm

Inhaling over long periods of high amounts of any nuisance dust may overload lung clearance mechanism and make lungs more vulnerable to respiratory disease.

Medical conditions which may be aggravated: Pre-existing upper respiratory and lung disease such as, but not limited to bronchitis emphysema and asthma.
Target Organs): Lungs
Acute Health Effects: None known
Primary Entry Route: Inhalation

I agree perlite just seems to be a place for stag water to form. Perlite keeps the water from moving around to keep more fresh. I use half inch of water at bottom of a 12 pack cooler and I crack my lid with a folded paper towel. I u see cotton up the FAE a little more by cracking the lid open a little more.

That is the whole point of a message board, to DISSEMINATE info, some correct, some less correct.

After all, you seem to be advocating deleting everyone but RogerRabbit's posts, which would yield a consistently accurate website, but only one man's opinion and experience..

I don't have the time to read all of RR's 12,500 posts, who does, but I would bet there are at least 25 examples of mistakes, questionable teks, or debatable teks at least. Maybe he NEVER was WRONG outright, but show me that I have been 100% wrong in one post...you cant...it's all up for debate, again, the whole point of a message board, and indeed a conversation.

Otherwise life becomes a lecture with one speaker.
