ireckonso Posted December 20, 2019 Share Posted December 20, 2019 This is the cheapest source of perlite I have found in thailand, its still expensive but can be reused many times. 100 litre bags are a large amount. http://www.higreenshop.com/category/399/วัสดุปลูกพืช-เพอร์ไลท์ Growing_carrots_hydroponically_using_per.pdf 1 Link to comment Share on other sites More sharing options...
FEBiochar Posted December 20, 2019 Share Posted December 20, 2019 Have you considered experimenting with biochar. Link to comment Share on other sites More sharing options...
ireckonso Posted December 20, 2019 Author Share Posted December 20, 2019 I think biochar has some great potential in soil use but for hydroponics you need a media that is inert. Way too much carbon in biochar that would cause problems. Link to comment Share on other sites More sharing options...

In an hydroponic system it would hold onto the nitrogen , which would then would not be available to the plants. Link to comment Share on other sites More sharing options...
