And... do you have any tilt angle of your flood table so that the water gets easier back into the rez?
Not really. Flood trays have deep grooves so any residual nutrient sits down in them and dont cause a problem. You can have a slight incline back towards the drain but if you use proper flood trays its not necessary.
Hey man
Youre still here klx?
Really interesting thread!
Been reading it already twice and i have one question left. You said that the stems should be a little above the water level. How crucial you think that is?
The reason I said that was during the development of this system I lost a few clones in the first week due to the stems going mushy and soft. I pulled them out and replaced them with extra clones I still had in the cloner if I had enough. But when I raised the plants up a tiny bit that issue seemed to disappear. It may have been that the clones had the pathogens before they went into the trays but raising them slightly fixed it.
You will find there are idiosyncrasies with your environment and you will need to alter things here and there slightly. Use my system as written here as a base and over your first few cycles you will see the areas that need tweaking to suit your environment and climate.
Good luck!
Guess if had to engineer it myself, I would have thrown money down the sink on the whole Canna range including the cleaning hassle afterwards. Saved me some try and error runs for sure!
