Your growing systems are destroying your plant nutrients. Learn how to protect your plants from Dying. Today’s post is about a Hydroponic water chiller. They are extremely helpful in order to grow healthy plants.
If you do not have knowledge about water chiller, then read this post till the end because today is the time for you to get some extra knowledge about indoor growing. Which can make you a successful grower even from the beginning.
What are Hydroponic water chiller and why do we need them?
Hydroponic water chillers are also called nutrient chillers. A nutrient chiller is basically a cooling device that is used to maintain the proper temperature of the nutrient solution in a tank.
Nowadays we have advanced nutrient coolers that cool the nutrient solution in summer season and heat it in winters. You can set them to cooling and heating mode according to the need.
The main motive of the nutrient chillers is to keep the temperature of the nutrient-rich solution under control. Because plants do not like warm nutrients. Warm nutrient solution loses the level of oxygen in it and the root zone gets less oxygen than required.
In a hydroponic system, a nutrient solution is used to supply food to the plants and plants also need oxygen to grow. when the nutritional water gets warm it loses the percentage of fresh oxygen in it but plants do need a high amount of oxygen to grow. The only possible way to increase the level of oxygen in the nutrient solution is to keep its temperature between the recommended range. Which is only possible when we use the best hydroponic nutrient chiller with our growing system.
Water is a good conductor of heat. It takes heat from the surroundings and raises its temperature. Normal water at 30 degrees C contains a 6 mg/L of oxygen whereas cool water has 9 mg/L of oxygen this is the reason experts recommend using water chillers with hydroponic growing systems.
Warm water with less dissolved oxygen leads to poor growth and lesser yield. The ideal temperature for the plant root zone is between 18 to 20 degrees Celsius which is 68 to 72 in Fahrenheit.
Water chillers ensures the good health of your plant especially in the summer season when the outside temperature goes above 35 degrees Celsius.
Hydroponic systems use a water pump to circulate the nutrient throughout the system. This circulation of nutrients also adds heat into the solution moreover the grow light, room temperature also contributes to making the water temperature above the recommended. If you are not using the Best water chiller with your soilless growing system then you are taking the risk with the life of your growing crops.
What is the ideal temperature of the root zone to grow healthy and disease free?
Scientifically there is no ideal temperature for plants to grow. Some plants like to grow in cold conditions while others like to grow in a warm environment. But when we grow plants at home without sunlight then we have to maintain the ideal temperature of the nutrient solution which works best for all indoor plants. For best results, experts suggest keeping the nutrient temperature between 20 to 22 degrees Celsius. This temperature is best for all types of green leafy plants, herbs and other famous plants like lemon, broccoli, tomatoes, etc.
If required you can increase the temperature up to 24 degrees but for a short period of time. Remember the growing behavior of indoor plants is different from field grown plants.
NOTE: Whether you are using DWC, DRIP, NFT or any kind of hydroponic grow system you will definitely need a nutrient cooling system. Without cooling system plant growth, yield and production are not guaranteed.
What if I put my plants in an Air-conditioned room?
Well, this might be a great idea for you not for your plant. It is easy to work on plants when we have an air conditioner in the grow room.
Air conditioner definitely keeps the room temperature low but for this, they suck the moisture from the air inside the room. Which make the air dry and dry air is much more harmful to plants. once your plants show symptoms of dryness then it will very hard to save them and get fruits to form them.
The cool air of AC makes the root zone extremely dry which can kill your plant. So, avoid this idea and use a nutrient cooler and give comfort to your growing babies.
ACs are meant for humans, not for plants.
Are there any alternatives to water chillers?
Yes, you can use one of the below-written alternatives to avoid the expense of extra growing equipment.
1.ICE PACKS: This is the cheap and best method of cooling. Put an ice pack into the nutrient reservoir and it will start cooling the entire system. But you cannot control the temperature, cannot set the temperature. The most disappointing thing is the cooling life span of ice packs is limited and you need the continuous supply of them.
Once the solution gets too cold there is no way to keep it warm and return it under the recommended range.
2.WHITE COLOR SYSTEM: Some growers advise to paint your entire system white in color. They give the logic that white color does not absorb heat energy like black color. White color reflects it back but we do not trust this method.
3.CHANE LOCATION: Changing the location of your reservoir can help a little. We already tried this technique and yes, it is helpful but not effective as it seems to be. The water pump, grow room atmosphere conditions will heat the nutrients quickly.
MOST IMPORTANT THING THAT YOU NEED TO KEEP IN MIND WHILE SELECTING NUTRIENT COOLER:
Always buy a hydroponic nutrient chiller that has the Titanium Heat Exchanger. We all know the nutrient solution that we use in our reservoir has an alkaline or acidic value. When the solution comes in contact with cheap metals it gets contaminated due to the corrosion effect.
High quality water chiller comes with anti-corrosive coating. Do not buy cheap quality products to save a few dollars.
STEPS TO CHOOSE THE CORRECT THE SIZE:
It is very simple to choose the right size hydroponic water chiller for your system. It totally depends upon the size of your grow system. Every cooling system comes with the ratings mentioned on it.
NO NEED TO GET INTO THE COMPLICATED CALCULATION WHICH BLOWN UP THE MIND.
Use our below written simple formula (100% accurate).
If you are using 50 watts output water chiller for hydroponics means this can cool the 50 liters of water. For every 1 watt, it cools 1 liter of water.
For example, I have a DWC system with 4 x 10-liter buckets and have the main take capacity 40 liters then I will require:
4 x 10 BUCKETS = 40 Litres
ADD 40 Litres of the main reservoir tank
Total comes 40 + 40 = 80 Litres
Now add 10% for Heat release: 80 x 10 Divided by 100 = 8
TOTAL REQUIRED: 80 Litres + 8 Litres = 88 Litres
Therefore, I will need a water chiller for my hydroponics with the power rating of 88 liters cooling capacity.
