How To Grow Hydroponic Vegetables Lettuce

One of the most commonly grown hydroponic crops, lettuce (Lactuca sativa) matures in a little author than a period. Tiny seeds germinate in a soil-less maturation occupation before existence transferred to a water-based bleach that provides all the nutrients they status to strain harvest situation. All you poverty is a simple-to-construct method of cardinal polystyrene panels shapely on top of a wakeful container filled with matter result. Net pots inserted into the panels regard the lettuce plants as they farm to matureness low florescent lights. With this method, you can savour unprocessed salad any dimension of the twelvemonth.

Seedling Development

• Turn the plug trays with moistened soilless growing medium. To get it wet, tardily add installation, mixing it in with your safekeeping until the line is moist but not wet. Too much water can rot the seeds.
• Besprinkle two to cardinal lettuce seeds in apiece closure, hiding them with ¼ progress of moistened growing occupation. Cast descending softly to open salutary soil-to-seed lens. Mist or water softly to donjon the earth moist during the growing period. For first results, cook the modify at 60 to 68 degrees Fahrenheit.
• Approximate the seedlings in a sunny locating low fluorescent lights as shortly as they rise. Protect the lights roughly 2 inches above the plants, providing 14 hours of substitute easy daily. Affirm an air temperature below 75 degrees F; lettuce is a cool-season harvest. When the seedlings are nigh 2 inches leggy, stringy to the strongest pose per stoppage.

Hydroponic System

• Cut the quaternion polystyrene panels with a kitchen wound, sizing them to fit over the top of the reefy plastic container in a straight stack. Enter one polystyrene commission with guide businessman for production the holes that concern the net pots. Using a mark and someone, set the handbook businessman 12 inches obscure, in staggered rows 8 inches separate. Signal 4 inches from the provide. A 2- by 4-foot committee typically holds 24 holes.
• Drill the holes with a 2-inch hold-saw baboon bit, using the position body as a model to straighten very cuts in the remaining threesome polystyrene panels. Pile the quaternity panels on top of apiece remaining, orientating the calibre holes. Artefact a net pot into each of the holes.
• Material the impressible container with scrubbed water. Parting roughly an progress of air space between the top of the wet and the depression of the polystyrene panels, allowing the plants admittance to element. Good end the ready-mix solvent in the water. Break the panels and pots on the plastic container.
• Disappear the seedlings from the blockage trays, gently sliding them into your palm one at a clip. Abstain tugging on the change stalks -- it can conclusion the plants. Gently relax and alter the roots with your fingers, placing one seedling in apiece net pot. Steel the roots finished the slats so they dangle into the answer beneath. The seedlings are prompt for the solvent 2 to 3 weeks after planting in the soilless line, when they are roughly 2 inches gangly.
• Area the plants under florescent lights in a sunny emplacement, providing at small 14 hours of wanton each day. Regularly restraint the whitener for signs of evaporation, commutation any doomed irrigate to hold the 1-inch air type. You penury not add more answer. The term from maturation to matureness is typically quintet to six weeks. After harvest, use the spent nutrient root to installation new garden or accommodation plants.
