so wonderin why EDIT (I THINK) MY humidity is low HMMMMMM i dont even have a hygrometer and can tell something is wrong.
And my only variable was my Perlite. Gave wife last clean stuff i had from a no problems runs to use in her garden. big mistake.
went poking around garden found some of it and its some stout ass stuff squeeze between ur fingers and it collapses but it takes force. Now go squeeze what is in use right now and it crushes easier than a Styrofoam peanut !!!
here is interesting read short to, Standard Perlite Gradations Defined
http://www.incon-corp.com/perlite/size.htm

here ya go if ya dont like links....
Standard Gradations of Horticultural Perlite
Fine, Medium, and Coarse Defined
Written by:
Bruce Schundler
For many years, horticultural perlite was understood to mean relatively large and often screened material. Usually it was used to provide aeration and drainage, and fine and medium grades were usually avoided.
In newer hydroponic applications, coarse and screened perlites were initially used and, again there was little confusion about what size or type of perlite was appropriate.
Beginning in the late 1980's and early 1990's, however, the grades of perlite being used and tested began to change. David Hall and others began working with 100% perlite media where the size and type of perlite being used was much smaller and was not screened. New horticultural studies by Hall and others began referring to fine and medium grades of perlite. Perlite Institute reports from The Netherlands in March and December of 1993, and work in hydroponics from Israel to England began referring to medium and fine grades of perlite being, and reports of turf and agricultural applications in India indicated finer grades were used. Eventually at meetings of the Perlite Institute and particularly during its Horticultural Committee meetings, there was confusion about what sizes and grades of perlite were being used and discussed in the many horticultural and agricultural uses of perlite, and in response a basic grading systems was developed.
Generally everyone in the perlite industry seemed to understand the basic parameters of "fine", "medium", and "coarse." Fines are those grades traditionally used in cryogenic insulation and fine plasters, medium grades have been used for plaster and concrete aggregates, and coarse grades are the two or three coarsest grades available from any perlite mining operation. To more carefully define these three grades, most studies have come up with sieve sizes or basic parameters, while others have just referred to "fine, medium, or coarse" grades in the hope that everyone will understand.
To avoid future problems, and misunderstandings, the Horticultural Committee of the Perlite Institute at the 1994 Mid-Year Meeting in Charleston, South Carolina approved a very basic specification for use within the perlite industry and others.
STANDARD SIEVE
or MICRON SIZE PERLITE GRADATION
Fine Medium Coarse
+16 mesh or 1 mm 10% Max. 60% Max.
70% Min.
+100 mesh or 150 um 60% Min. 85%Min.
------------------------------------------------------
ok interesting but info of what to buy not so good so i hope a list of manufactures from around yer home town can be mentioned.
PHARO - ROC is a good name to seek I can't spell this one but very good
Fox Farm is PRIMO both s.f. bay area finds
-------------------------------------------------------
IMO and i will be testing this post haste if your Perlite crushes between your fingers with ease IMO its shit.
If you have to use some pressure to crush thats the stuff.
------------------------------------------------------
and if you aren't having problems dont mess with it if you are in the market to buy Perlite i hope this helps

Please tell us how you know your humidity is too low. You want course perlite for best air conduction through it.

There will be little smell in a shotgun terrarium due to constant fresh air exchange and there will NEVER be condensation on the walls. I suspect your humidity is fine.

I will go get a Hyrg. 2morrow if store is open and I can get a model worthy of real calibration and not the back over method.
But still the grades of Perlite IMO need addressing this cheap excuse for a sustrate is WAY different than my older one.
And did u ever come across this GrowStone product.

RR since perlite quality, size, & quanity are key to the SGFC's success. And latly been bunch humidity problems. I just think this should be addressed cause Hydro store Perlite and OSH or Home Depot stuff are wildly different

if you go to most halfway decent hydro shops they will have various sizes of perlite. I know mother earth makes some stuff that is the size of crushed limestone, or about as wide as a quarter dollar and its some kickass shit for other uses. I havent ever tried it in a sgfc but Im sure it would work well in a pmp.

I have had humidity issues with the SGFC and it was not because of the perlite. The SGFC is meant to be used in rooms that have an RH above %30, anything below and you will run across humidity issues. Temperature can also cause problems. I could not get the humidity to stay consistent in my last project until I placed a small space heater in the room. I suspect that the increase in temperature caused more water to evaporate from the perlite and thusly raised the RH in the FC. Give it a try, it could help.

Faulty reasoning. A space heater in the room will always lower humidity, not raise it. I'm certain your 'humidity problem' was exactly like 100% of the other members here, which is a made in china hygrometer(piece of crap), a total waste of money and the leading cause of members trying over and over again to fix what isn't broken.

Guess this thread went totally wrong. Wanted to try and hi light that the Perlite you may may be using might be inferior and not doing the job it should. Looked at few batches from different stores and they were wildly differnt. And all this turned into was go out and run over ur Fuckin hyrgometer thread again
Ohhh well. I tried

I use the miracle grow perlite and noticed it does a shit job of staying moist/damp for more than 2-3 days, and seems really compacted, not loose and airy. I'll try to find another source of larger stuff.
--------------------
I challenge you to challenge yourself more! When you feel complacent and ready to hang it up, challenge yourself to get over it! If you fail, don't look at it as you didn't succeed, look at it as you would a rock face you're trying to climb. Stand back, wayyyy back, and look at it and plot another path. If you can't find one, shuffle down the way a little, a little change of scenery or a view from a different angle may give you the insight you need.

Are you using ungraded perlite? If it doesn't specify, like the miracle grow I buy, it's a mix. A mix of fine/med/coarse will have no problem compacting in your fc.

Then why the problem, and why the attitude?
I've typed many times not to use miracle gro perlite, and I've also typed at least a hundred times to use course perlite. Why do you assume that those of us who donate our time to help noobs enjoy typing the same shit over and over and over and over again for those who have been around here long enough to know better, but are still too lazy to use the site search engine?
When I say if your humidity is off in a shotgun terrarium, it's the hygrometer, I'd like to be able to assume someone who's been around for 5 years has at least attempted to help himself by using the search feature, if not actually read a few threads on the subject. It takes a hell of a lot less time to use the search engine than to wait for answers and then bitch when people don't write a book for the 100th time, just for you.
I can't believe how lazy the internet has made people. Back when we had to burn a tank of gas to hit ten different university and county libraries just to find an answer, you sure as hell didn't find people bitching about not being spoonfed knowledge because they were too lazy to look.

why not...... "why do u suspect this" or "ya there are many types of perlite"
And you mistake my total deflation for attitude alot of my threads end like this, people arguing about their own shit, flamers
I DID USE THE SEARCH ENGINE why i thought this would be a good topic to address. Guess im not as good at this internet stuff as you i cant apply my cabinetry or carpentry skills to it..... ma tools keep scratching the screen.
and yes been here quite a few years and i cannot recall anyone ever doing a thread on perlite or the grades forgive me. or i would not have wasted my time doing this.
me with the attitude you come at me with attitude.....

and who needs a hygrometer if you follow YOUR Guides and make and do everything to spec. it should work unless your surrounding conditions hamper it

I've definitely not read about the MG perlite, that would explain a TON, but I've never looked. I found this helpful (aside from the exchange of "attitude" as reading does not convey tone) because I've never thought my perlite was the issue I always thought it was other factors (room humidity, temp, FAE, soak time, etc.) and I honestly didn't think there was any difference in coarseness. The title is helpful IMO, I think the use of the "h" word may have thrown the discussion off, and there's not enough info in the first post as to the differences (aside from the grading). Sorry to try to diffuse the situation, if it's not my place. However I now know to use my MG perlite for plants, and order some coarse stuff.
