Introduction: How to Grow Lettuce Using a Wicking System
SELF WATERING SYSTEM
I have grown lettuce using a nylon wicking system shown in the attached photos. The lettuces are 4 weeks old after their transplanting from seedlings. This system is so simple and very effective. Once you fill the reservoir, you don’t need to water them again until they are harvested. The top level of water should not touch the bottom of the growing container. I gave ¼ cup of water daily for the first week, though. From then, all I did was to apply NEEM spray as an insect repellent once a week from the second week, foliar fertilizer spray on leaves and liquid fertilizer on top of each pot once every 14 days. The lettuce has been very happy as shown in the photos.
I HAVE SUCCESSFULLY GROWN 50 POTS IN MY GLASSSHOUSE AT THE BACKYARD. What I used for each pot were a nylon rope, a black plastic container, a transparent plastic reservoir (I chose a transparent reservoir to see the water level in case I need to top up the water), and a black plastic bag (for wrapping around the reservoir to discourage the algae to develop).
We have a be nice policy.
Please be positive and constructive.
