Asked for an update, Les reports that ‘Progress on the tomato front has been limited largely due to the lack of warmth in my shed. There are two controls on the light for different colored leds. One promotes vegetative growth and the coloured one stimulates the production of flowers. I want short plants, so I have 3 or 4 in one pot. The light is pretty intense which leads to short plants. The coloured light has caused such small plants to form flower buds already. I have also taken the opportunity to raise some seedlings. I recently increased the number of hours of light per day.’
