I started my windowfarm three weeks ago with four strawberry plants. I transplanted them (had to cut the roots) and for two weeks three of them grew very well (one flower even blossomed). By the third week, however, one of the plants became very week and the other two stopped growing (the third is just as stuck in its growth as when I planted it three weeks ago).
For the other pots I started seedlings. I transplanted a few to see how they would react and although they are alive (cherry tomatoes and zucchini) they have also stopped growing. The seedlings that I kept in soil continue growing.
The plants receive water every hour for 15 minutes. I change the water every week and add 6mL of nutrients (picture of components below) which is the suggested dosage (it says to double the dosage for plants that are need more). The plants don’t receive much sunshine (it’s almost always cloudy in Paris, but when they do it comes from the west for a couple of hours each day). Temperature is around 22 degrees C.
Do any of you have suggestions as to what may be going on and how I can revitalise the plants? Any suggestions about what plants would grow well?
