Backyard Aquaponics
A place to discuss aquaponics

I am new to the aquaponics way of growing and desperately need some help.

I have a green house housing my fish tanks and grow beds. Everything I planted is growing just not producing like it should. My main concern is with the tomatoes. They had lush growth but the blossoms keep falling off. I haven't harvested a single tomato all summer. Any clues on what could be the problem and how to fix it?

If theres no bugs in your green house you may have to get a cotton bud(thing to clean your ears with) and cross pollinate the flowers your self

Tried that...also tried shaking the plants and spraying them with blossom set. No luck... also my greenhouse is open on both ends to allow air movement. Could there be a imbalance in the water that is causing this?

It may just be the hot night time temps. Tomatoes set at night and dependant on the variety as to what temps set well during that time of year. I have early tomatoes still and they haven't set any new tomatoes for a month but are starting to set again with this cool spell. The blossom may pollenate during the day but it doesn't take until the night.

In my greenhouse in Arizona I dont get tomatoes untill fall and winter. As Baton Bill says tomaotes usually wont set fruit if nighttime temps do not drop to 75 deg F. At 80 deg. F. water temp, I cut fish food by half because most of the plants are wilting. Our raised bed soil gardens feed us thru the summer and AP all winter.
