Strong tomato vines require more light

January started out with poor light conditions for tomato growers in the Netherlands. Ron Kleijn of Van Iperen witnessed this with his own eyes during a recent visit to tomato growers. Under a photograph of a tomato crop on Twitter he wrote that there should be quite a bit more light. "At the moment 100 Joules is needed for proper growth, but last Friday we only measured 25 Joules, and the weekend wasn't sunny either."

Now that the tomato plants that were planted in late November and early December are slowly getting bigger, they need more light. In order to keep the plants strong without enough light, Ron advises to keep the feed water clean. "This can be done by adding stabilized hydrogen peroxide, so that if there is weakness, the nutrient water won't be an entry-point for diseases and fungi. Especially now that only a little water is being given, water can remain in the main pipe for a long time and should be monitored closely. By focusing on it now, you prevent problems later on during cultivation. After all, prevention is better than curing."
