I have tried to that before at the same place, some years ago, didn't succeed, don't remember why.

Now I will try harder and try to document what I do.

I bought a bag of seed for a peach tomato from a Thai company

I started 21 September, after 3 weeks I planted them in pots about 12 cm high and top diam about 12 cm.

I have made a cover for them, 70x100x150cm covered with "culture tissue" that we use in Sweden to protect plants.

I tried to follow instructions on the bag. On 20 Nov they have died. I am rather sure the reason is i have have put too much 9-25-25 to them.

I have tried to put new seed in small pots every 14 days.

Now I have 2 plants from 21 Sep in the cover. The have started to flower and i have tried to pollinate them with a brush. But I have not seen any positive result.

I think that the temperature is making the pollen  infertile.

This time have i been more careful with fertilizer, I am waiting to get a special bottle with tomato fertilizer from Sweden that you mix with water.

What do you other say, should it be possible to grow tomatoes at this place?

Can you give me any tips how to succeed?

I can think of no reason why it wouldn't be possible. 

 

From my own experience, don't water the plants or their leaves as they don't like wet leaves. This causes problems. Instead, just water the base of the plant. 

 

I grow mine in the soil, not pots, and I give them a really good, long watering about every 4 - 5 days. They seem to prefer this to watering a little every day. 

 

Re pollination; temperatures need to drop more before they are ready to pollinate. Up here in Korat, I have the best results from Dec. to Feb. when nighttime temperatures drop to 10, 11 degrees when the sun sets. 

 

Lastly, I only feed mine a balanced fertilizer, preferring organic, such as cow manure before planting out and compost or "green tea" after planting them in the soil. Check out "jadam fertilizer" by Huw Richards on YT for another organic way to fertilize plants.

I find to many bugs in this tropical climate under netting may work though.
