Care and Feeding of Young Plants
With autumn on the way, the temperature will be dropping so we need to start thinking about our next indoor crops! We can start with either clones or with seeds. Each have their advantages and disadvantages.
- Slow to start and may be prone to stretching if the light level is too low.
- Typically no sex selection possible when growing dioecious species.
- Easy and convenient way to introduce new genetics into a growing operation.
- Under proper conditions can be stored for long periods of time.
- Requires the care and maintenance of mother plants.
- Once a line of plants has been sexed, further selection isn't necessary.
- Typically larger than seedling so can take off faster.
- No genetic variation between clones taken from the same mother.
Roots are responsible for absorbing water and nutrients as well as supporting the plant. Without a proper base, the part of the plant outside of the ground can not thrive. If a young plant appears to be growing slow, it might simply be that it's focusing all of its resources on developing a root structure before the shoot and leaf development begins!
Young plants are very sensitive to extremes in the environment - this goes for fertilizer as well. Keep the concentration of plant food low, around 350 PPM and increase the strength once they've gotten bigger and have been transplanted into a larger sized container. Biostimulants, such as kelp and fulvic, can also be useful during early life as they will help to speed up growth in order to get the plant into the next stage of development sooner! They generally have a low amount of salinity, making it less likely that they will cause burning.
Humidity: Friend and Enemy
Without a proper root system in place, it is very easy for a young plant to wilt, which can lead to increased mortality rates if left unchecked. Increasing the humidity will prevent the young plant from drying out. However, having a high level of humidity also provides a perfect environment for mold to grow in. Start your plants under a humidity dome and then as soon as you can get away with it start offsetting the dome in such a way that there will be a crack allowing airflow. This also starts to wean the plants off of this moist environment. Once roots are visible (assuming the plants are in rock wool or peat pellets), they should be ready to handle being exposed to the atmosphere without any dome. Keep an eye on them though, just in case they do want to wilt.
