Frequently Asked Questions


AB Growing Supplies can take the mystery out of Hydroponics and indoor growing and bring some light (no pun intended!) to what has often seemed to be a dark, mysterious subject.

At AB Growing Supplies we consider it our business to answer your questions. After all, that’s what we do to earn your business. Chances are, your question has been asked before and if we don’t know the answer, we will help you find it.

Here are ten common questions we receive from people seeking answers to their indoor growing questions.

Q: What is Hydroponics?

A: Hydroponics is the science of growing plants without soil. “Hydro” means water, therefore, hydroponics is growing plants in water without using tradition soils. However, some hydroponics involves special types of growing media that are kept moist.

Q: What kinds of plants can be grown indoors?

A: Just about any type of plant can be grown indoors and they can range from flowers to herbs and from vegetables to medicinal plants.

Q: What kind of growing medium is the best?

A: Different growing media will give you different results, therefore you should choose a media that will give you the highest quality of growth and success. When we talk about soil we are not talking about dirt or potting soil, which should never be used. Ready Gro, Rockwool, Perlite and Coco are types of growing media.

Q: What are the advantages of indoor growth through hydroponics?

A: With today’s new methods and advances in technology your indoor growing efforts will result in much healthier plants that grow faster, larger and produce a better yield. With property growing media, lighting and hydration you can typically grow in 1-3 months. Another advantage is that you are creating your own ecosystem and are not subject to outdoor weather conditions.

Q: What kind of lighting will I need to grow my plants indoors?

A: There are essentially two types of lighting technologies used for indoor growing. The first is High Intensity Discharge or, HID, which is the most commonly used light of the early stages of growth. Another type of lighting is called High Pressure Sodium, HPS for short, which is introduced during the flowering and fruit-bearing stages. Fluorescent lights can be used for starting seedling growth. T-5 fluorescent bulbs are very strong and can be used for the entire growth cycle.

Q: What are the best types of waters used in Hydroponics?

A: Water is one of the “Big 4” as we call them…water, light, medium and nutrition. Some people consider water to be the essence of hydroponics and indoor growing. We tend to agree because our experience indicates that it is the single most important aspect of successful growth. Roots are the carrier of all of the nutrients that are bathing in the water and they roots channel the nutrients within the water. The quality of water has a direct and powerful impact on the results of your indoor growing efforts. We recommend Reverse Osmosis water purification. However, some indoor growers use tap water or filtered water but these can often contain counter-productive elements that inhibit maximum growth. Ask us for help with your water questions.

Q: Will I need to add nutrients or supplements to my indoor plants and how do I choose my nutrients?

A: In almost every case the type of growing you engage in will also determine what type of nutrient you should use. Another factor in selecting and using appropriate nutrients is determined by the type of growing medium you are using. What we recommend is the right balance and application of Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg) and even Silicon (Si). Each of these nutrients plays a role in your indoor growing results.

Q: Will I need to create special atmospheric conditions in order to get the best indoor growing results?

A: Yes, if you want to experience the best growth quality for your plants and the highest possible yield. You will want to consider adding CO2 to your growing room or growing tent. Plants love CO2. In addition, temperature control and air displacement through the use of fans will produce better results. Indoor growing through Hydroponics is actually the creation of an alternative ecosystem for plant growth. Every ecosystem is made up of light, temperature, humidity, CO2, oxygen, soil and nutrients. Each of these, when controlled will produce a rich result.

Q: What kind of testing and monitoring will I need to do to create the best plants?

A: The best plants are produced when the grower (that’s you!) monitors his/her ecosystem to insure the be pH balance and the right amount of total dissolved solids (TDS). TDS, PPM and EC are acronyms representing the amount of nutrient salts that are dissolved in water. Pure water will have a TDS, PPM or EC reading of 0. Distilled water will have a reading just above 0 (e.g. 4ppm or 6µS) and RO water about 5 – 30ppm. Total Dissolved Solids is measured as PPM (Parts per Million). Electrical Conductivity (EC) is measured in milliSiemens (mS) or microSiemens (µS), depending on the type of meter. Yes, it sounds confusing, but we can help you monitor all of these by using the right testing equipment…just ask us how.

Q: Okay, what about bugs and insects that can attack my indoor plants and create problems?

A: After a seedling produces its second set of true leaves you will want to treat the plant with “Bayer Tree & Shrub” in appropriate amounts. You can simply water these treatments into the established root system. This will give you about 60 days of coverage against white flies and aphids and in some cases has been shown to kill larvae. Do not use this product during flowing stages. Instead, you will want to switch to spraying your crop with “Neem” oil and something called “Pest Out” which will kill certain soft-body insect and mites. This will also repel insects. Foggers are used if you experience an infestation break-out. Foggers are used in rotation, usually weekly.
