Importance of light when growing vegetables.

Single tray seed room lighting.

Single tray seed room lighting.

All plants must have light reaching their leaves for them to produce carbohydrates on which they live.Plants that do not get enough light grow spindly and are very poor looking.Just be careful when selecting and planting companion veg plants that they do not exclude the light from one another.Most veg will need full sun.Some may get away with partial shade,but they must have direct sunlight for part of the day at least.That is the goodness of light with growing vegetable plants.

What kind of bulb is that, John?

John, If I was to sow my Alicante tomatoes now and leave the bedroom light on, would that be enough light for them?


Johnplotman Johnplotman 15 December 2009 21:53:51

Fran,it is a low strength 11 watt fluorescent giving out 60 watts.


Johnplotman Johnplotman 15 December 2009 22:02:39

That should do the trick Jacinta.Turn the tray or whatever,every day or so to keep them straight especially if the light is at an angle.Should they start to get spindly you will know straight away light is the problem.Once they are around 16 deg,you should have no problem.

Nothing grows well without light and sunlight is best especially for the human species!!!!!!!!!!!!!

It is inded Periwinkle.We need it all right.With the legumes,the peas especially draw atmospheric nitrogen from the light to feed the root nodules.No sun,poor growth.

Well done John!I hope they wont grow to tall untill you can plant them in glasshouse.

Very good. You can pay a lot of money for grow lamps. What is the difference between them and ordinary lamps? Is it wattage?


Johnplotman Johnplotman 16 December 2009 17:21:31

Thanks Liga,Mairin,Rachel,and Paul.

You can for sure Rachel.They would be very expensive i would be thinking.Wattage will be different all right but they also have special moisture proof fixtures.
