    I sometimes use screen leftover from re-screening a window. The holes are real fine and won't let the larger particles through, but you can wrap the screen around the media and it drains really quickly.

    YES you should WASH perlite because I've found plenty of GRAVEL in bags of perlite! Unless you want to inspect inch by inch for white-dusted gravel, the only way to get it out is to dump the perlite in water, swish it up, and throw away what's on bottom. Screening it before this is a great way to get rid of smaller particles, and the washing takes care of dust. I never screen it.


    I do use the cheap stuff since the local store only carries it and the kind with added fertilizer. Maybe you won't get any, or maybe it was a bad batch I just happened to buy three times.

    I have this creek nearby and have collected the fine sand at its shore. Who knows what's in there!

    I rinse mixes by making up a pot with rinsed materials and then leave them out in the rain for a while. For perlite, it only takes a few days. The more peat or sand (i.e. slower draining,) the longer it needs to stay out - pots of 1:1 peat/perlite or other mixes I actually plant into I try to leave out for at least a month or two. If I'm bringing them indoors, I'll sterilize them with boiling water a couple of times just beforehand.

    I use window screen

    I wash sand and perlite with window screen. I lay the window screen in a large cement tub and then poor in sand or perlite. I then dump water over it and stir it around. Then I pick up the corners of the screen and make a sack out of it and lift. The water pours out and I dump the water from the tub.

    Sand: I first use tap water as the sand is very salty here. Typical TDS reading is 900 the first time I pour in the water. I let it sit for a time and then pick it up like a sack and let it drain. I repeat the process a couple of times and then use RO water for a rinse or two. It takes quite a while.

    Perlite: Two ways to handle this. I had some perlite that was mostly dust. I put the perlite in the screen and picked it up like a sack. I then held my breath, stood upwind, and then started shaking in. The dust poured out. Then I rinsed it in RO water. I don't use tap water as it doesn't need as much rinsing.
