stupid perlite question

should the perlite be soggy? i tried to follow the 1 inch of perlite and the half inch of water rule and i put in 1 inch of perlite and when i read the "1/2 inch of water" i figured that when i dumped the atwer in it would go straight through the perlite to the bottom so i could easily measure a half inch. when i dumped in the water it all swirled together with the perlite so what i did was pour a shitload of water in so it was basically 1 inch perlite and 1 inch water, then i poured a 1 inch layer of dry perlite on top to make it 2 inch perlite 1 inch water. it doesnt seem to be putting off any humididty. i put a temporary spray shield in and the perlite is still down there....so should i just dump water in until the top laeyr gets moist?

Start over. First of all, ANY standing water will lower humidity. Put your perlite in a strainer and let water run through it from the faucet. Make sure it's completely wet. Allow to drain for a minute or two, then dump into your terrarium. A two inch layer will provide 99% humidity for up to three weeks, at which time you simply repeat the process for the next flush/cycle. RR

wow that really makes a lot more sense then "1/2 inch of water"...if i flollow what you just told me does that mean i dont have to add the extra "1/2 inch"...if not all i have to dois wet it, strain it, dump it, and its good to go?

correct. and on a personal rec. i like to place another opened 1/2 pint jar filled half way with straight dry peril along with the moistened bottom 2" of moist peril in your chamber. it seems like this would add to the amount of water being forced between the two... the moist peril (whole bottom layer) and the dry (jar half full of dry peril)... thus increasing your humidity levels. i can get my chamber anywhere from 98 to 60 % RH, by ways of increased/decreased airflow. anyway, best of luck man, -shoomR

I have to agree and disagree I've used water at half the depth of perlite but I've also always used 2" perlite and water at half that depth and it's always performed beautiful. The problem comes when people totally saturate their perlite it then loses all it's wonderful surface area as well as it's humidifing effect. Anyway with or without a bit of water it takes some time for the RH to acclimate after putting the FC together, also hygrometers are often off unless you get a decent one so here is a place to wisely spend that money.

i am not seeing any condensation in my FC after wetting, straining, and putting the damp perlite in. this isnt normal is it? (its been about 3 hours)

Two things to consider one a well sealed FC allows the RH to build up better number two condensation occurs because of a temperature difference between the inside and outside of a container not so much as to higher RH values (FACT).

i think condensation normally comes from having a difference of temperature from the inside to outside. if teh inside is hotter the edges of the tub are being cooled from the outside and so droplets condense there. pretty much if you have wet perlite and its been in there for a few hours just assume you have good RH. beucase that stuff has the surface area of russia.

I have a question related to the topic of this thread...
I'm setting up my fruiting chambers using the "poor man's terrarium" template, putting plastic thai food containers together instead of 2L pop bottles. That being said, I need to find a more adequate way of assuring my humidity to be acceptable. I was originally going to put in an inch of perlite, and pour about 1/4 of a cup (which would be the 1/2 inch) of water over it, place my cakes on aluminum foil (is this a good idea?/is there a better substance to place my cakes on?) over the perlite, and fan twice a day, leaving the FC sealed. Does this sound alright, or should I go another route? I want to use this fruiting chamber technique, so any suggestions that would work within these bounds would be greatly appreciated :-)
