how day is to grow tomatoes
In general, tomatoes take around 60 to 90 days to grow and then ripen. In a hydroponic system, because you are providing the plant with the absolute best growing conditions, I would expect this to be sooner, and you should be enjoying your tomatoes within 60 days at the very most.omatoes are fairly hardy plants, meaning they can thrive in a wide range of temperatures. Generally, a temperature of 18Â°C to 25Â°C is desirable during the day, and a temperature of between 12Â°C and 18Â°C at night time.
