After the harvest ... what now??

I use about a half cup in the laundry sink... that might hold 20 gal of water and a bucket full of rocks. I use a 1" piece of PVC pipe I drilled some drain holes in (most of the way up the pipe) so the water can drain without plugging the sink. If I want to hold the water in, I have a 1 1/2" solid piece of Pvc pipe that slides over the drilled one and it keeps the water in. Then when I want to drain the water, I just slide the larger pipe up and out and the smaller one actually drains. I generally rinse twice and I'm done.

Good Topic. I'm early in my growing experience and I finished my second grow last year and started another one recently. I was fearful of adding anything like bleach so I used straight tap water which I figured contained enough chlorine for my needs and then soaked for a day, thoroughly flushed three times and then spread out the hydroton to completely dry out.

Well the instructor at the Oaksterdam University says he uses Bleach to disinfect everything, including walls etc.

I clean my rocks in 5g buckets with about a 10% bleach/water mixture. After that I rinse the rocks with clean water. Also use the same ratio mixture to clean the inside of my tent and everything else.

Also like LOC, I use the physan20. I usually only use it if there was any nasties during the grow just to make sure.

DON'T USE BLEACH! Use hydrogen peroxide.
