Answer 2

Hydroponics

Hydroponics has taken plant cultivation to the next level. In fact, people who were never interested in gardening or growing plants are now doing so, simply because they are intrigued by the concept of growing plants without soil.

But, what are the advantages and the disadvantages of hydroponics cultivation?

Lets take a look at the advantages of growing plants using hydroponics cultivation technique. There are quite a few benefits that comes with growing plants in soilless culture like:

Less space required

Less growing time required

Labor and garden maintenance is reduced

Water conservation

Nutrients are recyclable

Save money by recycling nutrients

Pest, weed, and disease problems can be controlled easier

Plants grown hydroponically avoids soil borne pests

More control over the plants rooting environment (Easily manipulate the root zone's temperature, humidity, darkness, et).

Higher Yields



Although hydroponics is probably the future norm of plant cultivation, it still has its disadvantages, including:

High set up cost

Growers require skill and knowledge to maintain optimum production in commercial applications

Because each plant in a hydroponics system is sharing the exact same nutrient, diseases and pests can easily affect each plant.

Plants react quicker to changes in the environment, however, if this change is for the worst, plants will quickly react to it; showing signs of deficiency or trouble.

Hot weather and limited oxygenation may limit production, and can result in lost crops

As with most things, it's important to understand the advantages and disadvantages of hydroponics. This will allow you to make informed decisions on what application is "right" for your individual requirements.

Aeroponics

Aeroponics can limit disease transmission since plant-to-plant contact is reduced and each spray pulse can be sterile. In the case of soil, aggregate, or other media, disease can spread throughout the growth media, infecting many plants. In most greenhouses these solid media rsequire sterilization after each crop and, in many cases, they are simply discarded and replaced with fresh, certified sterile media. A distinct advantage of Aeroponic technology is that if a particular plant does become diseased, it can be quickly removed from the plant support structure without disrupting or infecting the other plants.  

. Additionally, the nutrient solution throughput of each of the systems was estimated. shows how nutrient solution throughput in the Aeroponic system is moderate compare to that of conventional NFT and even the soil substrate technologies.

sorry Could'nt find the disadvantages. hope this helps

Answer 3

Hydroponics and aeroponics give a fast and consistent product to the market in a self contained and efficient manner. It can now be done very cost effectively in an organic manner and combined with aquaculture, as in aquaponics, you get the best of both worlds, but a bit of management trials and tribulations. It can be done anywhere as a facility does not rely on land use but the cost of a facility is comparable to the cost of the land it replaces. There is a great deal of engineering and labor involved to set up and maintenance so one needs to be well versed in agriculture and  facility management/ construction. Maintenance and production are more like factory work than farming at times and a whole lot of effort goes to cleaning where a farmer might be weeding and mulching. Seasons are non existent in a green house environment, just a set of climate influences to be adjusted with equipment. Hydroponics allow a tighter control of production and many variables do not exist that a farmer has to deal with, provided of course the hydroponics producer is good at what they do. Mistakes in the green house can be costly and hard to fix. I've been in the industry for a long time and I've seen it all. The good is great and the bad is an unbelievable nightmare.
