How To Grow Buttercrunch Letteus Rockwool And Nft
An inert medium (such as rockwool or oasis cubes) can also be used to produce transplants. This system has the advantage of the rockwool block acting as a reservoir of nutrient solution in case of pump failure and helps to anchor the plants in the nft channel.

This video shows you how to do hydroponic lettuce production using rockwool.
How to grow buttercrunch letteus rockwool and nft. This allows you to fit more plants into a small space. Lettuce also grows best in cooler environments. As a general rule, the flow rate in your channels should be around 1 liter per minute, which is about.26 gallons per minute or just shy of 16 gallons per hour.
Seeds need light to germinate; We grow genovese basil, thai basil, lettuce leaf basil and greek basil in an aeroflow 18 hybrid nft / aeroponics hydroponics system using hydroton expanded c. Take the main stem of the donor plant and cut 3 to 4 inches of leaf stem from as close as you can to the main stem of the plant.
Either way, i always just dampen some paper towel, sandwich some seeds in the paper towel, put in a ziploc bag, and let them germinate on a heat pad. The first step to setting up your system is to set up your water reservoir. We actually grow lettuce on a commercial scale but the idea is the same scaled d.
Rockwool grow cubes have a ph of around 7.8 which is a little on the alkaline side. Pelleted seed will split open when moisture is added, allowing In an nft hydroponic system, the growing channels are set at a slight tilt to create a rate of flow that results in a very shallow stream of nutrient solution.
Now that the pipe and the transplants are ready, it is just a matter of fitting them in. Although this lettuce does not require a large quantity of water, it does require consistent watering. Rockwool is preferred for germination and after germination, the cubes containing the emerging seedlings are set in the nft trough or hole!
The surface area of the container that will serve as your reservoir can be whatever you require but make sure the depth is a minimum of 8 inches. Most lettuce requires light at low radiation levels to germinate. Check out one of the pictures below for the picture of the overflow pipe.
Sow seed 1/8 inch deep, 1 inch apart in rows 12 to 18 inches apart. Ebb and flow systems see your lettuce plants growing in trays, either directly in the trays themselves or in pots that sit in those trays. It can be kept in the side or in the bottom also.
Grow lettuce seedlings outside of the water culture system, and once they are around 2 inches tall, transplant them into a net pot and place the pot in the reservoir. When it’s time to harvest, you can cut individual leaves from your plants so that you don’t have to remove the entire head. Fill 3/4 of bowl with tap water.
Rockwool is a very popular media in nft lettuce and herb systems. This reservoir will hold the necessary water and nutrients that your plants will require. Sow at a very shallow depth by covering with a thin layer of growing medium.
The nft system doesn’t use an automatic timer connected to the water pump like other hydroponic systems so the water pump runs constantly. Also, if you're using rockwool cubes, i think you're supposed to soak them or flush them with water or something to neutralize their ph (i've always used leca, so i'm not 100% sure on that). Lettuce grows best in temperatures of 45 to 80 degrees.
Take a ph meter and remove the black cap from it. An nft (nutrient film technique) sliding bench system (a.k.a moving gully system or mobile gully system (mgs)) is the most efficient user of greenhouse space for any type of nft system. First we take a bowl and that is large enough to have all of our rockwool soaked in water.
Growing lettuce in a nft system also means that you can make use of vertical gardening techniques. Lettuce and herb growers use a single 25x25x40mm cube which is sufficient to sustain the root zone of the plant from the seedling stage until maturity. In case of placing it in the bottom, ensure a depth of 2.5″ of nutrient solution is maintained.
Keep the air temperature between 68 and 75 degrees for best results. Requires moderate levels of water. Ensure that soil is moist but not muddy.
Your lettuce will take longer to grow in cooler temperatures but will taste better. The rooting medium can also be a mixture of various coconut fibre and perlite. Be careful not to damage the node.
A large quantity of cubes can be placed on ebb and flow propagating tables without using up much space. Nft and rockwool in this system, plants are established on small rockwool slabs which are then positioned in channels containing recycling nutrient solution. Make sure to water your donor plant well the night before you begin propagation.
It’s advised to have a little more volume capacity than it is needed rather than to be short. Prepare rockwool for planting lettuce. In hydroponic growing, lettuce is prone to calcium deficiency, according to andrew.
Place ph meter tip (the point that cap was placed before we removed it) in water and turn the ph meter on. They require a minimum of two workers to operate the systems and it is very easy for staff members to plant, harvest and clean the system. The smaller plugs are also ideal for transplanting into other growing mediums and are suitable for nft, drip, and deep water culture systems.
