Torn between coarse perlite and downright HUGE perlite for SGFC
    #19368557 - 01/04/14 02:22 PM (10 years, 26 days ago)

My local hydroponics shop has two types of perlite, one is coarse (#3) which looks like medium sized gravel, the other is huge, never seen perlite that big, I'm taking about each one being 1" (the size is #4), I know the bigger the perlite the more airflow, but can perlite be too big? I searched the site and tried to find a thread about this big ass perlite to no avail. I've read about the mess perlite can leave with the SGFC and when I grew back in '06 before the known importance of FAE I used regular grade with no holes in my chamber, but now that I'm adding the holes I'm just wondering if I should just get the huge perlite, I can buy it and post pictures later today if that would help, the bag isn't expensive, the brand is mother earth, which doesn't make a difference I'm sure. I can always exchange it if it turns out to be too big but I'd rather just take care of it at once and not have to go back because I already have to return the powdery shit they sell at OSH as medium grade (ha!) that I bought before I knew about this place. Thanks!

Beats me but I would say it's too big. I would probably go with the coarse #3

FAE
This is a phenomenon (Fresh air exchange) in a properly built SGFC this is constantly happening. The perlite is naturally cooler than the surrounding air this moves molecules closer to eachother as the lose kinetic energy. This creates low pressure which pulls air up through the bottom holes. As the air moves through the perlite it picks up humidity and keeps the chamber at or above 90%RH. This occurs naturally without the fanning and is why we like to have no fans in the room and is also why fanning after misting is not a replacement for FAE.

Here's a pic that has both of them I believe

The left should be #3 and the right is #4
