Some New Organic Techniques

Rice hull as mulch. But it makes me wonder, isn't rice treated with lotsa pesticides? Is rice hull a good mulch material?

I saw this Solar Water Drip Irrigation system on SOAP's FB page. I got curious, since it's been extremely hot lately, so I tried it on one plot. I also did a clay pot method I read about in bio-intensive gardening. You're supposed to bury a clay pot in the soil and fill it with water and cover it with mulch. I put used coffee filters inside so it would seep through the soil slowly.
