Hydroponic growing and product questions
What can be grown in hydroponics?
Virtually any plant can be grown in a hydroponic system. Leafy greens and most herbs are perfect for almost any hydroponic system. Vining crops like tomatoes, cucumbers, and peppers grow well with hydroponics but will take up more space and may require trellising.
What is the most important factor in hydroponics?
We are primarily concerned with the pH of the water used to make up nutrient solutions and irrigate plants. pH is a measure of the relative acidity or hydrogen ion concentration and it plays an important role in plant nutrient availability.
What are the advantages of hydroponics?
The main advantages of hydroponics are greater water efficiency, less nutrient runoff, the quantity and speed of yields, fewer pests and diseases, no arable land is needed, and it takes up less space than traditional farming.Why are fans important for hydroponics?
There are numerous reasons why air movement fans are important for hydroponics. Humidity around plants is typically higher when growing in this way, and this can lead to an increased risk of mould and bacteria. A fan will keep air moving, lowering the humidity level, and helping your plants to stay healthy. View our collection of air movement fans.
Do hydroponic plants need sunlight?
Light is required for hydroponics, but not necessarily sunlight. Many hydroponic growers grow exclusively indoors, replacing the sun with grow lights that use either LED, fluorescent, incandescent, or HPS bulbs.
Are LED lights good for hydroponics?
LED lights are a fantastic alternative to more traditional HPS grow lights as they’re energy efficient and boast a customisable spectrum. Their impressive technology means that LED lights can help growers achieve unrivalled plant growth and an improved yield.
What Should Be the Distance Between Grow Lights and Plants?
Proper grow light placement is crucial for healthy plant growth:
-
HPS Grow Lights:
- 600W: 35-64cm
- 1000W: 41-79cm
-
LED Grow Lights:
- 450-550W: 51-76cm
- 600-850W: 61-66cm
- 900W+: 66-107cm
Adjusting grow lights correctly helps avoid light burn and ensures even light distribution in your hydroponic setup.
How often should I water my plants?
Overwatering and underwatering are both common problems for novice growers. Overwatering is known to cause the amplitude of problems like mould, fungus, root rot and nutrient lockout.
Underwatering usually stuns plant growth, but it’s easily fixed and causes way fewer problems than overwatering. So in that case a golden rule of thumb is to water only once the topsoil 3cm to 4cm deep feels dry.
What’s the best way to protect my plants?
What Temperature and Humidity Are Ideal in a Grow Room Environment?
Maintaining the ideal temperature and humidity is crucial for successful hydroponics. During the day, the grow room temperature should be between 24-26°C, while at night, it should range from 18-22°C. For humidity, aim for 50-70% during the vegetative phase and reduce it to 40-50% during the flowering phase. Proper temperature and humidity help optimise plant growth in your hydroponic system.
What pH Range Is Best for Growing Plants?
For soil-based growing, keep the pH levels between 6.0 and 7.0. In hydroponics or soilless substrates, the ideal pH range is 5.5-6.5. Regularly monitoring pH ensures that your plants can absorb nutrients efficiently, which is essential for any grow shop setup.
What Is the Perfect Environment for Drying Your Harvest?
After harvesting, the drying room environment plays a vital role in preserving quality. The temperature should stay at 21°C, and humidity should not exceed 50%. Ensure proper airflow by using a small floor fan to prevent mold and maintain optimal drying conditions for hydroponic supplies or traditional growing methods.
What Is the Ideal Environment for Seed Germination?
The best environment for seed germination includes a temperature range of 17-25°C, with the ideal being 22-25°C. Humidity should be kept at 70-90%. Using quality hydroponic supplies, like seedling trays and grow lights, can further enhance germination success.
Is Transplanting Important in Hydroponics?
Yes, transplanting is essential for plant health and growth. It is recommended to transplant 2-3 times per growth cycle, typically when the plant doubles in size. Transplanting prevents overwatering and ensures the ideal moisture level in the substrate, promoting robust root development—a key practice for any grow shop enthusiast.
Is Eye Protection Necessary in the Grow Room?
Absolutely. Grow lights emit intense light, which can damage your retina within just 15 minutes of direct exposure. Always wear specialised eye protection to shield your eyes while working in the grow room.
What are the main requirements of a hydroponic system?
- Lighting
- Growing medium: coco coir, pebbles, propagation media, rockwool or soil
- Nutrient solution: base feeds, beneficial bacteria & enzymes, feed additives, flowering boosters, flushing additives, organic nutrients & vegetative boosters
- Water and oxygen
- pH and EC control
- Temperature and humidity control
- Space and support structures
Can I use flowering boosters from different lines of nutrients?
The short answer is yes, if it’s not a PK-based booster like Dutch Pro Explode in which case you should be aware of other PK products you put in since it might cause nutrient burn. On the other hand, boosters like Canna Boost Accelerator or Shogun Sumo Active Boost can be interchanged without any problem.
What EC is ideal for various phases of plant life?
The ideal range for clones and seedlings is 0.5-1.3, 1.3-1.7 is ideal for vegging plants and 1.3-2.0 is ideal for flowering ones. To be able to tell the levels one should get an EC meter like Bluelab CF Truncheon.
Which heater is better?
Which heater to choose depends on many factors and your personal preferences, but generally speaking oil oil-filled radiators are used to heat bigger spaces and heat them more evenly, while fan heaters are used to quickly heat small spaces. Also, it should be considered that fan heaters dry up the airway quicker. To make sure the temperature is always on the spot you can take a look at the Lighthouse Wireless Thermostat.
Do I need an intake fan?
If you're on a budget, the short answer is no. Your extractor fan should be more than enough to make and keep negative pressure in your growing space. Generally, intake fans are usually used when fresh air is taken from further away places than grow room to boost and keep pressure in the ducting. If yes, it should be half the power.
How to avoid powdery mildew?
One of the most common problems amongst growers is powdery mildew. The most common issue for it is bad air circulation around the grow room which can easily be fixed by adding more fans. Also, sometimes an issue is too crowded room and no spaces between plants. Humidity should also be considered and in later growing stages do not exceed 45%. And in case you already have it Mildew Protection Spray or CX PMT Treatment should help you out.
Do I need a humidifier?
Yes. Most of the time humidifier is a must in the grow rooms since usually natural air humidity is around 50% and that’s not enough for the vegetative stage. Also, if you use HPS lights they dry up the room quite a bit too. To achieve perfect humidity levels we highly recommend using a controller, like Ink Bird IHC-200.
Which extractor fan to choose? EC or AC?
AC fans and Box Fans as well are usually a bit cheaper to purchase at start, but they aren’t very efficient at energy savings and usually they make the notorious humming noise at lower speeds, EC Fans on the other hand might be a little more pricey to start with, but they are very efficient on energy since they utilise DC current and are silent at all speeds, without any humming.
Is there are differences in pH down solutions?
The main differences would be active ingredients which lower pH, such as Phosphoric acid like in Growth Technology pH Down or Citric acid like in Ferro Citric Acid. Citric acid is considered natural and organic. Other than that, it’s down to the ratios of how concentrated the pH down is.
How can you spot nutrient burn?
Nutrient burn is quite a common problem among growers. It can be harmful and can stun growth or even kill plants altogether. Usually, it’s easy to spot in the early stages which you can notice by the edges of leaves being dried up and curly, especially the tip of the leaf.
What is the Nutrient Film Technique (NFT) in Hydroponics?
What Are the Most Common Grow Room Pests and Diseases?
The most common grow room pests include spider mites, thrips, and aphids, which damage plants by sucking their nutrients. Powdery mildew, root rot, and bud rot are the most frequent diseases, often caused by poor airflow and excess humidity.
To prevent and control these issues, use sticky traps, organic insecticides, and proper ventilation. At Go Green Hydro, we offer a range of pest control and disease prevention products to keep your plants healthy.
