Indoor Hydroponic Gardening, Ideas, Tips, Techniques 

introduction to Indoor hydroponic gardening

The thought of indoor gardening is essentially just growing plants indoors. There are many different reasons for indoor gardening and multiple styles and techniques that can be used to achieve the goals of indoor gardening. This may be at a residential home, within a business location like an office building or restaurant, or any other sheltered area. There are multiple types of indoor gardening, including container gardening, hydroponic farming, and vertical farms. Indoor gardening can be small in extent and done by the normal homeowner or it can be industrial in scale and take place in massive greenhouses.

A step by step guide to indoor hydroponic gardening

You must be thinking of mess that indoor gardens or plants are going to create in your houses like your clean floor flooded with water and soil. But one of the most promising and trouble-free ways of indoor gardening is hydroponics.

Hydroponic gardening is done completely devoid of soil. As an alternative, it relies on growing plants in water with the support of a suitable growing media, and the use of the nutrient solution provides the essential nutrients that would come from the soil if the plants were grown outdoors traditionally in soil beds. Roots won’t have to spread out deep into the soil looking for nutrients and you won’t have to take up extra space with large pots or drainage trays. Hydroponics indoor gardens are versatile, enables indoor hydroponic garden DIY and portable that will allow the maximum use of available indoor space and permit you to grow possibly everything irrespective of the growing season in a controlled environment.

Anyone with an indoor garden knows very well that how messy it can be when you’re trying to plant, repot, and fertilize your plants. The hydroponic garden system might engage a little bit of spilled water or some stray clippings but these types of messes are much easier to manage than dark, rich soil getting ground into your beautiful floor or carpet this is one of the prime advantages of hydroponics.

Techniques and ideas of indoor hydroponic gardening

There are many techniques of indoor hydroponics based on the structure of the hydroponic system and methods used for providing this nutrient solution. The type of system you make a decision to make use of will depend on your budget, the scale of your crop, and the type of plants you plan to grow for hydroponics at home. 

Passive method – The simplest form of hydroponic gardening utilizes the passive method, permitting you to establish when and how much nutrient solution is to be provided to them. Wick systems are one classic example, in which Styrofoam trays are filled with growing medium and plants. These trays simply float on top of the nutrient solution, facilitating roots to take up nutrients and water as required. 

Flood and Drain method – one more simple technique of hydroponic gardening is the flood and drain method also recognized as Ebb and Flow. This technique requires the use of a pump and appropriate levels of the nutrient solution must be maintained to avoid the pump from running out dry. The technique uses a water pump on a timer to flood and then drain the root system with water and nutrients. The water reaches a height where it will soak the roots in growing trays or individual grow pots and the excess water drains through an overflow tube. When the pump shuts off at the designated time, the water will drain back down to the reservoir until the pump turns on again. This system provides the roots with alternating periods of air and oxygen than water and nutrients. 

Drip System methods – The drip system is a fairly clear-cut concept and it works exactly as it sounds. The plant roots are placed in a growing medium such as perlite or gravel. When the timer turns the pump on, the nutrient solution is ‘dripped’ onto every plant. There are two basic versions, recovery and non-recovery. Recovery drip systems accumulate the surplus runoff while the non-recovery ones do not. Drip systems have the requirement of a pump and are regulated with a timer as well and nutrient solution is pumped from a reservoir, through tubes, to drip onto the roots directly. The growing medium and roots are drenched and then the solution drips back down into the container and flows back to the reservoir. This system is suitable for large plants with an extensive root system as the growing medium will preserve some of the moisture and keep the large root system well hydrated.

All hydroponics system designs function on a similar principle, plants grow up in a sterile, soil-less medium that permits the direct delivery of nutrients to the roots from a nutrient-enriched water solution. These systems differ mostly in structure and framework. The other two techniques of hydroponics based on framework are: 

Nutrient Film Technique (NFT) of indoor hydroponic gardening

 The Nutrient Film Technique (NFT) has plants suspended in plastic baskets and sometimes small Rockwool cubes over long tubes or trays usually PVC pipes. Majorly PVC hydroponics plans are based on this system only. The system involves a shallow stream of a nutrient solution which flows through a downward sloping channel. The roots of the plants hang into this stream and soak up nutrients from the steady flow and then drain back excess into the reservoir. The best merit of this system is individual plants can be removed and replaced without disturbing the rest of the system.

This active system requires a water pump to run, but other than that it is set up very much similar to a wicking system. One potential drawback of the NFT system is that any system failure or power interruption leaves the roots vulnerable to rapid drying so one has to keep the backup ready.

This system is favorable for small, fast-growing hydroponic plants such as lettuce, herbs, and baby greens these are best indoor hydroponic plants beginners must start with such manageable plants for hydroponics at home.

Water Culture of indoor hydroponic gardening

Water culture is the system most often used for DIY hydroponics plans since it is the most inexpensive system to produce small, water-loving, quick-growing plants like lettuce or spinach. This system can be as large or as small as you want and are easily adapted to any number of settings. The plant is placed in a grow basket or net pot on top of a reservoir filled with nutrient solution and the roots hang down from this basket, totally submerged in the solution, However, it is not the best choice for large or long-lived plants, or those better adapted to drier conditions.. Since the roots are continually submerged they will have need of aeration to avoid suffocation. Aeration can be facilitated through the use of an air pump, air stones, or a falling water system that generates air bubbles through agitation. 

Aeroponics of indoor hydroponic gardening

Like to the NFT, aeroponic systems have bare plant roots suspended in little or no growing medium. Rather than flowing through the system, the nutrient solution is sprayed at regular intervals to the suspended roots, facilitating maximum uptake of water, nutrients, and oxygen and also prevent the roots from drying out. This is perhaps the most proficient delivery system, but also the most expensive. Though, if you can afford the initial outlay, this system will possibly give you the best results for your investment. Aeroponic systems build an environment for the roots that provide as much oxygen as possible. The developing roots are suspended mid-air within a growing chamber, using no or little growing medium so this way entire root system is exposed to nutrients.

Tips for indoor hydroponic gardening systems.
  • Before finalizing the hydroponic system and hydroponics kit consider the probable growing habit and size of the plants you will be growing and make sure there will be room in your system for its roots as well as a strong enough frame to support your plant growth stages.
  • The plants will only thrive if they are receiving abundant nutrients from hydroponic nutrient solution and this absorption is possible and best if the pH of that nutrient solution is within the appropriate range as demanded by the plants. If the pH is out of that range, it won’t matter how good your nutrient solution is, the plants will experience malnutrition and all your efforts will go wasted.
  • There are several ways to test your pH which is an. The easiest and cheapest way of testing is pH test strips, which are extremely quick and easy to exercise and is available at any gardening store. You just dip the strip in the solution, swish it around for a specified amount of time given in the instructions by manufacturer, and then match the colors that it develops on a corresponding table that comes with the test strips. For measuring the exact pH you can also invest in electronic pH meters.
  • The answer to How often to water the plants in your hydroponic system is simply long enough to get the roots wet, but not so much that they suffocate because of over-watering. The rule is simple if the growing media and roots appear to be getting too dry among watering, increase the frequency.
  • Don’t undervalue the significance of the water quality you utilize for your hydroponic systems, it can make a big variation in the health of your plants. use a good quality filtered water right from the beginning, tap water, well water, stream water, rainwater all have problems like pathogens, disease, fungal traces, and even chemicals may also present.
  • If you have hydroponics setup, like ebb and flow system and a drip system or NFT systems you have to be extra careful because of the recirculation of these systems, pH, and nutrient amounts can change often, so consistent monitoring is suggested.
  • Avoid the degradation of your valuable nutrients by storing them in a dark place and avoiding exposure to sunlight. Some nutrients packaging or hydroponic grow guide comes with specific instructions such as storage in black bottles, so read the instructions carefully.
  • Many crops require shorter daylight periods to trigger flowering/fruiting so this has to be managed well since indoor hydroponics system may not have proper access to light so the option is to install grow lights. The lights have to be turned off and on at exactly the same time each day for this use a digital timer to maintain the photoperiod. The plants must be kept in complete un-interrupted darkness throughout the dark period. For this either makes use of an entirely blacked-out room dedicated to the garden or else use a cover.
  • The best answer for how to start a hydroponic garden is don’t begin if don’t you have all tools and equipment ready. You will require a completely dark area, a high powered fan, light source, appropriate hydroponic gardening system, hydroponic nutrients, an oscillating fan, a TDS meter (or EC meter), a pH test kit, and probably an air conditioner.
  • A container filled with water all the time has maximum chances of algal growth to avoid algae growth your nutrient reservoir must be a dark color or opaque (avoiding light) and should have a lid. This is significant because algae will attract fungus causing root damage in your plants. The reservoir must be sufficient enough to hold all of the nutrient solutions in your system in addition to the nutrient solution in the reservoir itself.
  • The best approach to cut off the expense of maintaining and reusing a hydroponic system is to make use of a re-usable grow medium. Expanded clay pellets or lava rocks (as in a DWC system) are the good options when it comes to reusable medium. The growing medium must be cleaned of any roots and soaked to remove the old nutrient solution.
  • Your plants must have at least 6 hours of sunlight every day so it’s imperative to position them in a spot that receives sufficient light.
  • The optimum water temperature is between 68 and 72 degrees Fahrenheit so make sure you are maintaining the system within the range.
  • Change your water and nutrients entirely every two weeks have an additional reservoir with plain water when waiting for the next nutrient change.
  • Clean and sterilize the system between crops and the refilling of nutrient solution.
  • Maintenance of hydroponic system regular cleaning is a decisive part of leading a successful operation because this practice will keep your system free of pests and diseases. Scrubbing down the growing buckets or grow trays is necessary for the cleaning practice to stay away from pathogen build-up or any accumulation or clogging. This process is easy and can be completed by using a scrubber and a 10 percent bleach solution. This is exercise must usually be done after each growing season or after every harvest.
