My plants have grown a lot lately.
The paprika, tomato and chilli are getting so big that they almost cover each other and now I´m worried that they won´t get enough sunlight. I am considering cutting off the tops of the plants (to make them shorter and more stable) but on some online gardening communities they say that that is a bad idea because it makes the harvest late. But is that a problem? The windowfarm is indoors and I don´t mind waiting.Are there other reasons not to?

Do or don´t? Any suggestions?

Now I have finally got my windowfarm up and running.
I made the structure  last year, sowed the seeds several months ago, and planted the tomato plants in the structure  about one month ago. So far I have watered by hand, but today I managed to build the pumping system.
However, I have encountered some problems. The two biggest so far:

1. The system will not start up again when it has been switched off. I wanted to have it on a timer but every time it´s on standby I have to rearang the air needles to make it start. I will try to find a solution, but if you have an idea, please write a comment.

2. The air pump I am using is not the quietest. I have tried to put the pump in a box with towels to muffle the sound. But it still sounds too much. And I’m a little afraid that it will overheat in there. Maybe I´ll pick it apart and check what it is that makes the sound, or I´ll try to change the box or I´ll just buy a new pump. Some other suggestions?

Today I also started watering with a nutrient solution adapted for hydroponics. I hope it will make the plants a little stronger with time.

Since the windowfarm hangs in a window with little natural light I have put up an extra lamp. A fluorescent light fixture with a light that simulates daylight.
