Video on Nutrient Change of DWC
I decided to record the simplicity of a Deep Water Culture Hydroponic system nutrient change. From up-potting into the DWC, this batch of Simpson Elite has been on half nutrients. I have found that the 40 day mark is ideal for increasing the nutrients to full strength.
My results have shown this timeline to allow harvests to continue for another 50-60 days without bolting and without the need for additional nutrients. Since the lettuce is designed for full harvest in soil at 42-46 days, we are getting both earlier harvesting (10 days) and extended harvesting (50 days) with the hydroponic efficiency. The harvests are "partial" in taking maximum 40% of each plant every 2-3 days.
