  1. Very interesting, may try it but I have another question. I’ve been trying tomatoes hydroponically for the last three years. Not having a lot of success, nothing but blossom end rot even though I’ve used lots of cal-mag. Any suggestions?

  2. Hi Gary, calcium and magnesium deficiencies are what cause blossom end rot, so if you are supplying these elements and the problem is persisting, maybe your plants aren’t able to take up the nutrients properly. Make sure your water’s pH is between 6.0 and 6.5 or nutrient lockout may occur. That would be our first guess as to why you might be struggling.

  3. Thanks, I’ve mostly been 5.5 to 6.5. I’ll start watching it closer. I really appreciate the input as I’ve spent some on a hobby greenhouse and so far I think my tomatoes are @$6.00 each!

  5. Is it feasible to set up an aquarium and set your plants in pot on the grate? would the aquarium set up do this? (I grow some orchids where the roots touch minimal water)

  6. Hi Barbara, it sounds like you are describing a stripped down aquaponics system, which can work great for growing plants. It’s hard to advise you without knowing exactly what you’re doing and what plants you are growing, but as long as the plants are getting enough water, oxygen and nutrients and are being adequately supported, I don’t see why this wouldn’t work.

  7. I’ve successfully grown lettuce in the past but can’t get my seeds to take anymore. I’ve tried new seeds. The material in my net pots turns green pretty quick after starting over. Any thoughts?

  8. Hi Jodi,
    Sorry to hear you are having issues all of a sudden. We have a couple of suggestions for you: 1. try starting the seeds outside of the system or simply lowering the water level until the seeds germinate and get off to a good start. It sounds like the seeds might be drowning. 2. Maybe use a little h2o2 to clean out your system, net cups, and tools to prevent mold growth, or use new starter plugs to make sure no contamination continues into your new grow. Best of luck getting back on track! — Ryan and Mike from Fifth Season Gardening
