Aeroponic Plant Cloning
By Maximum Yield 2 April 2019
Aeroponic plant cloning is commonly used in vegetative propagation (cloning) by professional gardeners. Vegetative propagation is an asexual form of plant reproduction. A section of stem that includes a growth tip is separated from its parent plant and then induced to produce roots. This allows the plant parts to grow in different locations. They are referred to as clones because separating the plant will make a genetic representation of the original plant. One of the best examples of this kind of cloning is the spider plant (also known as Chlorophytum comosum) that can take root in contact with the soil and later becoming separate plant on its own.
Meristem cells also known as undifferentiated cells, that can be used as the variety of specialized cells according to the needs. This is important to note as all meristem cells start out the same no matter where they are located in the plant; a fact which is exploited in rooting cuttings. Growth tips and root tips contain such high concentrations of these cells that they are both called apical meristems. Secondary meristem cells are also found along the stem, trunk, and branches where they generally develop to increase girth. Secondary meristem cells can be used by inducing to form new root tips and maturing into root cells.
Fortunately for many plants, this can be as simple as keeping the end of the stem opposite the growth tip moist in room temperature conditions and under moderate lighting. There are many ways to go about rooting cuttings. Some of the simpler methods include placing cuttings directly into a moist growing medium or in a glass of water set on a windowsill.
Air stone and air pump are connected to each other and is added to the water. This adds air to the water and helps it to stay oxygenated and preventing it from being outdated. While any portion submerged would be better described as a deep water culture (DWC), the above water stem that is exposed to the water droplets propelled by the popping of the air bubbles benefits from an aeroponic environment. An aerated system such as this tends to perform better and have a success rate than a simple glass of water under the same conditions. To add something new to the existing method, an air-lift driven sprayer can be used to concentrate and raise the popping bubble effect, allowing the ends of plant stems to stay at a height above the waterline.
Since at this point, as far as the plant is concerned, it has stopped being air-pumped into the water and become water-pumped into the air, it can be considered an aeroponic system. At least until the roots grow to the waterline. Almost all aeroponic systems eventually become hybrid aeroponic-DWC systems at some point, as the roots will tend to grow down far enough to reach the nutrient solution.
All lifts function because air bubbles will rise in the pipe, and water trapped between air bubbles will rise as well. This principle is commonly illustrated in under-gravel aquarium filters. Air is released at the bottom of a riser tube. As the air bubbles rise, they carry some of the water along to be returned near the top of the tank. Water from the tank passes through the gravel bottom to replace the water lifted out of the tube by the air bubbles.
Air-lift sprayers follow a similar method. Air is pumped through an airline into the sprayer riser near the bottom. The nutrient solution enters through a hole in the tube and is lifter along with the rising air bubbles. At the top end of the tube, the bubbles burst and spray the accompanying nutrient solution. Plant stem ends are suspended within range of the spray, allowing them to stay moist and get nutrients.
To prevent the spray from making a mess of the surrounding area, a lid with holes cut for plants covers the reservoir and sprayer. The bottom end of the stem is suspended below the lid (but above the waterline) by a collar or net pot, with the rest of the cutting above where it can receive moderate light. Cool (but not cold) room temperatures are commonly considered ideal.
