Backyard Aquaponics
A place to discuss aquaponics

trying to grow cucumber but the plant keep dieing while other plant like tomatoes and broccoli have no problem. i have salt my pond at 2-3ppt all the time.
i know some plant do not like salt... is cucumber one of them?
at what salt level (?ppt) with cucumber be alright?

Yep, 3ppt seems to knock cucumbers around... especially if they're young...

last year my cuc's shrivelled as I was using bore water @ 900ppm... this year rain water and all plants are booming.

However, I think more important to cucumbers is Iron and potassium. Young cucumber plants need a good amount of iron and if the system pH is too high, the Iron is locked up and the cucumber plants struggle. Supplementing with chelated Iron can help cucumber plants in AP.

(In regular hydroponics cucumbers need a rather low pH and are medium to heavy feeders.)

Yeah, my first (rather salty) growing year did not get good cucumbers, they are doing good this year so far.
