Cherry Tomato into Aeroponic system

Hi,

Im trying to get some cherry tomatoes out of the plant but seems nearly impossible :/. The plant does the flowering quite well, it seems, but then no fruit at all...

System is running into aeroponic with water at 6,4 ph / 24ºC and room temperature at 30ºc.

Some pictures:

Can someone advice me?

Thanks

Honestly, I wouldn't know a first thing about aeroponic, but in your pictures, plants look very healthy, good color and very important that they do have flowers...

If there is some kind of imbalance/stress, tomato plants will drop their flowers without setting a fruit, but, if it is simply a "pollination" issue (since there is lack of bees and natural mild breeze), maybe that would attribute to no-fruit set? Have you tried to shake the plants few time a day?

If not, try doing that, pollen should drop and fruit would set... Some folks take it step further, using electric brush, touching the base of the flowers for few seconds. But with cherry varieties, that's just too much, just shaking gently would do...

Regards,

1st tks for your kind reply!

I've done some hand polination shacking the plant and flick the flower gently... even using an electric device to buzz them but so far nothing... They don't set the fruit.

What kind of imbalance/stress can happen?

The water temperature is around 26ºc with ph 6.4 and a fan is always on (even during night time). Im starting to became frustrated :(

JP,

Since I don't now enough about aerophonics (though I wish I could grow tomatoes in the wither here), it's very difficult for me to give any advise... I do know, that a very delicate balance of nutrients must be maintained at all time, aside from pH and the temperatures...

Your plants look great, it seems that they have everything they need, they set the flowers, and yet, you have no fruit... Do they simply drop flowers? If so, you may want to consider reading this article:

https://organicgardenworks.com/2010/06/09/blossom-end-rot-tomato-plant.aspx

Sometimes, blossom end rot and flower drop can be attributed to the same issues listed on that page. I hardly imagine that a cherry type tomato would ever get a blossom end rot, but if your flowers are dropping, give it a read, you may find some useful info to your situation... Best of luck!

Regards,
D

What do you mean by "drop"? They just die...

Why don't you give it a try to hidroponics/aeroponics? I believe you can have tomatos all year :)

Tks for your help i'll keep researching! Im tired to plant veggies... they're easy :)

Drop compare to Die - usually, when tomato plant experiences "blossom drop", flowers fall off the plant while still very bright yellow. If the shrivel and die while still attached on to the plant, this maybe something else altogether...

I did look up your lamps, since I'm not familiar with them, and personally, I see a potential issue with color. I see that a page describes this color temperature as 2700K, which is considered to be very warm light, not nearly the temperature of the daylight (daylight is 5000K-6000K or so).

These daylight temperatures are what I use on my tomato seedlings (earliest varieties), always plenty of blooms and all setting fruits before I transplant my earlies into containers for outside...

Regards,
D

I read somewhere what plants needed 6400K for veggies and 2700k for flowering.

Hope its not wrong

Here are my transplants with 5000k-6000K lamps:

Setting flowers and fruit just before the transplant:

Hi Duh_Vinci,

Today i've changed my lamp to a CFL 6400K with 200W to see what happens :)

Noticed that my flowers are quite small comparing to yours... That's cherry tomato or another one? Regards,
Joao
