@popcornsutton,
Kind of experimenting after reading an article about it. The perlite gets lots of "clean" water pH5.5 the soil gets the nutrients and should be able to go up to about ec 4(?!). They should be able to handle it deu to fresh water being available all the time. It's said to be growing faster and vigorous this way. So far I see little difference with 100% soilgrow though π just a lot more measuring
