Controlling your hydroponic plants |
| We suggest that you first familiarize yourself with our helpful tip labeled ‘Maintaining your hydroponics system’. In that publication we encourage you to check the appearance of your plants every day, among other issues. The tables below will help you to trouble shoot problems with your plant environment.
Click here to go to "Maintaining your hydroponic system" For plants we talk about two stages: the vegetative (leaf and stem growth) and the generative (bloom and fruit growth). A plant should always have a good balance between the amount of leaves and the amount of blooms or fruit. As an example consider a tomato plant. If you have too few leaves, the plant does not make enough photosynthate (sugars). This will reduce the availability of sugars and water flow to the flowers and growing fruit. The results are smaller and possibly fewer fruits.
When you use the tables as a tool for trouble shooting, please do not change all the parameters at once. This will result in the plant becoming too vegetative or too generative. Choose the parameter that differs the most from the table and adjust that one. Wait a while to see if you have achieved the desired effect. If this does not perk up the plant, then find the next obvious parameter to change. It is almost like making soup. If it doesn’t taste good, you don’t mix in a number of ingredients all at the same time to make it taste better. You add a little bit of one, then taste. Then you might try another if it didn’t work. You apply the same idea when you encounter a problem with your plants.
VEGETATIVE
NOTE: During the night when you do not have your grow light on, the humidity will naturally go up a bit as the air cools. There is no reason to worry about that. During the night just maintain the 70º room temperature and the slab water content.
GENERATIVE
NOTE: Do not inject CO2 at night. |
