Does anyone have a worm farm or brew their own worm casting tea for use on lawns and landscapes? If you have any pics/videos or ideas to share I would love to hear/read about them. I have seen some homeowner models online but would like to know about larger scale farms or brewers. I would like to try to start with something homemade before dropping thousands on a worm farm and them more on the brewer. I saw a great worm farm unit for about $5,000.00 and the brewers for $3,000 and up. I don't want to drop that kind of $ yet. I have some tank sprayers (100, 175, and 200 gal each with 250 ft of hose and spray gun) I would like to set these up to spray worm casting tea on residential lawns.
