frickin humidity...
    #3353770 - 11/13/04 12:05 AM (13 years, 9 days ago)

I set up a PMP, not too big, but it works right i think, i got the 2 bubble stones in with lava rocks, and the humidity only seems to get up to 90% max... I got enough water in there and the hoses are conneced, is there another way to increase the humidity? I tried to wrap the suckers corners up to make sure none was escaping but its the same. I got a cake in there now and its actually starting to pin a tiny bit ( at least they look to me like the start of pins, they actually look like small whiteish penis's :P ) Yeah but i was wondering, is there a quick and dirty way to get the humidity up another 5 % to 10% or can B+ grow at 90% humidity just fine? Another question, if they do grow at 90% humidty what will happen to them? will they grow to a certain point then abort and die off? or will they just grow smaller? im wondering..

Your lava rock level should be at least 1" above the water line. Too much water will lower humidity. And specifically to your lava rocks, I can't tell you if 1" works or not... maybe you need 1.5"...

In any case, good luck

does your hygrometer even read up past 90% humidity.. a lot of them don't....... and yeah.. they'll grow just fine at 90% humidity.

was this reading after a few hours with a closed lid? is your pump big enough to cycle the air 2-3 times an hour? i've heard that airstones (long wide things with foamy stuff on top) don't work as well as bubble wands/walls/bars (long tubes)

As long as you mist accordingly, 90% humidity is sufficient. But just remember the purpose of the PmP: Semi-automated, set it and forget it growing.

If youre working just as hard as you would without the equipment, youve done something wrong. (Not that you have)

My PmP only goes up to about 92%, but Im using and 80 Gallon container, and it is using casings, not cakes. So humidity for my unit is less important.

I am also using lava rocks and bubble wands. In the end the greatest use is steady air exchange without removing the lid, which is an invaluable and essential component to your grow.

My advice is leave the water, and add more lava rocks. Keep the ones on top saturated and misted with H2o and H2o2 sollution.

Good luck

Kido

It depends on your PmP size, Id say 2 inches of perlite and 1 inch of water is sufficient. Definately enough to keep your bubble wands submerged. I use lava rocks now, much cleaner. To each his own though.

Have you ever used perlite? I have found that it is sort of difficult for the humidity to get high because all that extra perlite, not submerged, is dry and sucking up all the humidity.

After a day or two it gets wet enough from the humidity that the top layer of perlite is able to give the air its humidity, but then it has to rehydrate from perlite below, which in turn has to rehydrate from the perlite below, which has enough water.

What I want to find out is how deep of an evaporation layer of perlite is optimal for fast rehydration and therefore highest humidity.

That is an analog (analog just means not digital). It is also most likly a shitty one. Stick with your setup it will work beatuifully!
