This is how we grow 18 purple cauliflowers vertically on an aeroponic tower #cauliflower #farming
This Video is from the Youtube channel: “Agrotonomy”.
1. Tower Assembly: It takes about 10 minutes to assemble one aeroponic tower, including the reservoir, growing sections, submersible pump, irrigation tubing, and the top shower cap that distributes nutrient solution through the tower. From there, everything is on autopilot.
2. Rockwool: Since there is no soil, the plants are grown in agricultural rockwool, a soilless substrate made from basaltic rock that is melted and spun into fibers. It provides excellent water retention while still allowing plenty of oxygen around the roots.
3. Transplanting: In this video, we are growing Amethyst purple cauliflower. Because cauliflower plants become very large, we plant only two per level on opposite sides. With 9 levels, that gives us 18 plants on one tower.
4. Automatic Irrigation: Once transplanted, irrigation is fully automated. The bottom reservoir refills with nutrient-enriched water as needed through irrigation lines connected to a gravity-fed tank.
5. Irrigation Cycle: The submersible pump runs 3 minutes ON and 12 minutes OFF continuously, totaling about 4.8 hours of irrigation per day.
6. Aeroponics: During the OFF cycle, the roots remain suspended inside the tower in an oxygen-rich environment. This helps support efficient nutrient uptake and rapid growth.
7. Pest Management: The main pests we deal with on brassicas like cauliflower, cabbage, and broccoli are caterpillars. As a preventative, we apply Bt (Bacillus thuringiensis), a naturally occurring bacterium used in organic farming that stops caterpillars from feeding after they consume treated foliage.
agree.. any microplastic contamination been tested?
These aeroponic towers are made from BPA-free, UV-stabilized, food-safe materials that meet the highest safety standards, including U.S. FDA and European RoHS guidelines. These high-quality plastics are designed to avoid harmful leaching, ensuring a safe environment for growing plants. The materials are engineered to withstand outdoor conditions without degrading.
What do you do with al this food😮
We consume what we can and donate the excess crops.
They are so beautiful! Do you not get cabbage moths and caterpillars? They have no pest damage at all
Thank you so much! We definitely get cabbage moths and caterpillars, especially during the cooler seasons. As a preventative, we spray Bacillus thuringiensis (Bt) every 7 to 10 days on all our brassicas, even before we see any signs of caterpillars.
Bt is a naturally occurring bacterium approved for organic farming that stops caterpillars from feeding, while being safe for humans, pets, and beneficial insects. We spray both the top and underside of the leaves, since that’s where the moths lay their eggs.
