Bato bucket tomato8/31/2023 ![]() To do this, take the plant sites per section number from earlier and divide that by the plant sites per channel. ![]() Knowing the plant sites per channel, we can now move to determining how many channels are required for our system. ![]() This will reveal exactly how many plant sites each channel will hold.ġ44” channel / 8” spacing = 18 plant sites per channel Next, divide the channel length in inches by 8 to account for spacing. To determine the number of plant sites per channel, first multiply the channel length by 12 to determine the channels length in inches.ġ2’ channel x 12” in a foot = 144” channel Our NFT channels are available in 8, 10 and 12 foot lengths, with the 12 foot length being the most efficient for production on this type of scale. We recommend 8 inch spacing on center for lettuce and leafy greens, meaning that each plant site in a single channel should be located 8 inches away from one another. With our plant sites and harvest cycle now discovered, the next step is determining our plant spacing. With such a large plant site requirement, an operation such as this would be best suited for two sections of channels, with 1,250 plant sites per section.Ģ,500 plant sites / 2 sections = 1,250 plant sites per section To find the number of plant sites our system requires, we need to multiply our weekly production goal by the number of weeks that the lettuce will remain in the system.ĥ00 heads per week x 5 weeks = 2,500 plant sites Factoring in 2 weeks in a nursery system leaves us with 5 weeks that the lettuce will remain in the NFT channels.ħ weeks – 2 weeks in nursery = 5 weeks in NFT systemĪs an example, our production goal is 500 heads of lettuce per week. On average, lettuce requires 50 days to go from seed to harvest, which means it takes approximately 7 weeks to become harvest ready. ![]()
