At 4 weeks the Kratky system is showing progress, not as much as I’d like but there has been some challenges with the weather (this is set up outdoors). Maybe we will have some harvest by the 6th week?
This is usually a dry time of year but we have about six inches of rain over the last two weeks, this showed me a big flaw in the initial design. Since then I have added drain holes so the boxes don’t flood over. Even with this a few of the plants are doing well and a few more have now sprouted. I’m liking this setup, very easy and inexpensive once the bugs are worked out.
