WATER SYSTEMS FOR HYDROPONICS AND GARDENING

Water pressure is important to know when installing a reverse osmosis System

The first thing we need to know when installing a reverse osmosis System is the inlet water pressure. 

All membrane manufacturers base their production calculations on 60 psi(4,3 kg/cm2) and advise in most cases a mínimum pressure neccesary of 40 psi (3kg/cm2) for the RO unit to function correctly.

Importance of a good strong inlet pressure

With a good strong inlet pressure, RO units will produce a good quantity and good quality water, while also sending less water to drain.

Without a correct water pressure (less than 40psi/3kg) Ro units will produce less water, worse quality and also send more water to draon.

4 kg/cm, the optimal pressure
4 kg/cm, the optimal pressure

 

For this reason, all Growmax Water Garden Reverse Osmosis Systems include a pre-pressure gauge, pre-installed after the sediment prefilter and before the green carbon block pre-filtre and in all cases, before the membrane.

How to obtain the best results with your RO unit

If after installing the RO unit you see the pressure gauge below the mínimum requirement (40psi/3kg), you shoould install a Growmax RO Pressure Pump Kit, to obtain best results for quantity and quality of water. This Pump kit will raise your inlet water pressure by 40psi/3kg. Above your corrent inlet watwer pressure.

GrowMax Water has two Pump Kits available, the first for the Power Grow and Maxquarium units, then also a HF (High Flow) Pump to be used with the higher producing Mega Grow unit.

Remember that good, strong water pressure is the key to an optimum functioning RO unit.

Tips for watering roses and rose bushes

The Catalan tradition on the Sant Jordi’s Day is giving a rose. Taking this special date, we suggest some tips for watering your roses, and so keep them well maintained throughout the year.

The first months of rosebush

During the first year of planting, lack of water is, in many cases, the cause of a rosebush fail. So watering during this stage is the key. Because during the first months, the roots are still shallow, and need to absorb more water to develop.

To learn how to water our rosebush properly, we must consider the type of soil in which we will plant it. If for example there is a sandy soil, the rose bush will not retain water very well, and will need more frequency and amount of watering, especially at first. If instead it is a clay soil, it will hold moisture longer and will need less water.

Watering the rosebush depending on season

As with most plants during summer times, it is important to moisturize the rosebush. With the heat and drought, plants need more water and more frequently. In areas of excessively hot weather, it is recommended to water the rose bush once every day. In areas of more moderate heat is sufficient watering every two or three days.

Generally it is important to water them early in the morning or in the evening, but never during the hours of more heat and sunshine.

During the winter, the rose tree has no leaves and therefore do not need to water it frequently. Except that it still young or you’ve planted in pots. In the latter case, it is recommended to water it regularly so that the roots do not dry out.

¿Hose or watering can?

You can use both, it depends on your comfort and the garden space you have available. If you use the watering can, it is advisable to use with artichoke-shaped neck, as the water will not come in a single stream. In this way you won’t erode the soil from the roots. In the case of using the hose, it is important to avoid high pressure jet.

In both cases it is essential not to wet leaves or flowers, and apply irrigation on the foot of the plant. You should also try never swamping the rose bush because they can rot the roots. Yellow and falls leaves are a sign of rotten roots.

If in addition to these tips, you provide your rosebush with water of high quality and without chlorine, you guarantee healthier roots. In order to manage this, you can make use of water filtration systems, which remove 99% of chlorine, Herbicides, Pesticides and Volatile Organic contaminants. This way you will guarantee success and health for your rose bush and the other plants in your garden, and very convenient, because the filters include connectors for external taps.

Spring has arrived, begin your outdoor crop

Spring is the best season for starting outdoor growing. In Spain, the weather starts to get warmer, cold nights decrease, increase daylight hours … factors that make this the best time to start growing outdoor. But what about the water quality you will use to irrigate?

Often in the preparation of appropriate tools for cultivation, we forget the importance and quality of a fundamental element: water. This element is the basis for growth, and although weather conditions are now more favorable for growing, without a filtration system that gives good quality water, plants do not proliferate as we would like. Because water isn’t equal everywhere…

EC control levels and chlorine

For example, high amount of minerals, a high EC, or heavy metals in water can block the absorption of nutrients needed by the roots. If this situation happens, no matter the quality of the nutrients that you use for plants, because due to the high concentration of mineral salts and calcium in the water, they won’t absorb it. As a result, our plants will show deficiencies.

On the other hand, during the warmer months, municipalities add more chlorine to the water networks to prevent the spread of viruses and bacteria. During this time, the water contains more chlorine, which burn before the roots and removes the beneficial bacteria of fertilizers.

To prevent these problems and to ensure the quality of water, there are water filtration systems, which eliminate up to 99% chlorine. If water in your area is very hard, and has a high EC, with RO systems  you will eliminate up to 95% of salts and heavy metals, and up to 99% chlorine. In this way, you will add the necessary nutrients that your plants really need, and they will grow healthier.

So remember, if you’re going to start outdoor cultivation with the arrival of spring time, consider the quality of the water you’re going to irrigate. Using filtration systems or RO can help you get the best results.

10 REASONS TO LOWER THE EC AND ELIMINATE CHLORINE FROM YOUR WATER

There are several reasons to lower the EC and eliminate chlorine from your water. If your plants could talk, they would ask you for quality water, and we explain you why.

eliminate chlorine and lower the EC

1. MORE NUTRIENTS FOR OUR PLANTS

Keep in mind that our plants can receive an EC of up to 1,4 to 2,2, according to the type of plant or growing stage. If, for example, the water we use has an EC of 1,0 then we will ONLY be able to add from 0,4 to 1,2 of nutrients to reach our maximum levels. If on the other hand, we start with an EC in the water of only 0,1 or 0,2 or even an EC of 0,0 then we will be able to add much more nutrients to our plants.

2. HEALTHIER ROOTS

By lowering our EC we eliminate salts that we don’t want in our water. This will give us healthier roots, by avoiding lime scale build up in the roots and they will be able to absorb 100% of the added nutrients.

3. PROTECT OUR SOILS

We know that soils contain Beneficial Microorganisms whose function is to protect plants roots, by keeping them clean and healthy, so that they have maximum ability to absorb nutrients and fertilizers. However, when we water our plants with chlorinated tap water, the chlorine, a chemical, kills off our beneficial bacteria that is present in the soil. Chlorine will also burn our plants delicate uptake roots.

 

4. MAINTAIN A BALANCED pH

By using a garden reverse osmosis system to lower your water’s EC, we achieve a balanced pH, as RO water has a pH of approximately 6,5.

 

5. AVOID NUTRIENT LOCK OUT

A high EC may contain larger quantities of hard water minerals, like calcium and magnesium, also known as limescale. High amounts of these minerals, together with added doses of nutrients, can BLOCK or saturate plants roots, prohibiting them from absorbing the added nutrients, which is also known as “nutrient lock out”.

 

6. PROTECT OTHER MICROORGANISMS

In the case that we have to use specialized microorganisms (for example to kill worms or other parasites, etc.), it will not make sense if we water with chlorinated water, because the chlorine will kill these microorganisms that we have just purchased.

 

7. AVOID GROWING PROBLEMS

Many times we encounter small problems or challenges with our plants and gardens, without knowing where some of these problems come from (yellow, dry leaves, burnt tips, stunted growth, etc). Professional growers assure us that if we begin growing by using a low EC water, many of these problems can be avoided, as we will know EXACTLY which nutrients and what quantities our plants are receiving.

 

8. ACHIEVE BETTER RESULTS FROM OUR NUTRIENTS

By starting with PURE WATER, our plants will not absorb any undesirable elements that can be present in the water and therefore we will achieve a 100% effectiveness out of our added nutrients and fertilizers.

 

9. PURE WATER IS THE FOUNDATION FOR GROWING

Just as a house must be built with a good, strong foundation, you must also start with PURE WATER to have a strong foundation for GROWTH. Knowing that we start with a clean, chlorine free, low EC water, is the right way to help our plants to GROW TO THEIR FULL POTENTIAL!

 

10. QUALITY WATER FOR US AND FOR OUR PLANTS

Finally, one simple question. If for our own personal drinking water we prefer a clean, quality, and chlorine free water (often bottled), why wouldn’t we give the same water to our plants? They also DESERVE QUALITY WATER!

HARD WATER FOR YOUR PLANTS IS NOT RECOMMENDED

What is hard water? Hard water is that which has a high concentration of the mineral salts calcium and magnesium, also called “limescale”. The formation of limescale is a problem for our plants and our plants roots.Calcium phosphate is what our bones are made of and it is 95% water insoluble. The calcium phosphate often falls out of the nutrient solution as lime scale. Once lime scale is formed both the calcium and phosphorus become unavailable to the plant.

We can use our EC meter to measure the total quantity of dissolved mineral salts in our water but that still will not tell us what percentage of those salts are hard water minerals. 

 To compensate for excess minerals, hard water nutrient formulas are usually lower in calcium and magnesium, with reduced levels of sulfates, so a hard water nutrient formula complements the minerals already present in the water. 

Also, if water is excessively hard, or an analysis shows  toxic levels of trace elements such as sodium or boron, the water should be filtered or processed.

HOWEVER, most growers will simplify water quality management by using only reverse osmosis water. RO removes all (90-95%) of the mineral ions, so the grower starts with clean, pure water. Therefore, if you use RO water all of the essential elements will come from your nutrient solution, not from the source water, creating the perfect mineral balance for plant growth. 

RO is definitely recommended for any applications where a water softener is in place. A water softener does not remove the calcium and magnesium from the hard water, rather is replaces them with sodium ions, often at toxic levels. If sodium exceeds 50ppm the plants may not be able to reach their true genetic potential. 

RO water is also perfect for topping off your reservoir between nutrient changes, replacing water lost to evaporation without adding any unwanted minerals.

Experts say that if an analysis shows that even one element is approaching toxic levels an RO system is definitely needed.

CHLORINE – THE ENEMY OF OUR PLANTS

All municipal water supplies contain chlorine, a chemical disinfectant used to kill off deadly bacteria and virus in the water supply. This chemical in turn, can directly attack our plants and gardens. We know that chlorine is present in our drinking water because we can smell and taste it’s presence, many times making it undrinkable. So the question is: If we don’t want to drink the water from the tap, why do we want to give it to our plants?

Now, more than ever, in the summertime, with the high temperatures the local water companies add extra high doses of chlorine to the water supply to combat the bacteria and virus that can be present.

Let’s talk about how chlorine can affect our plants. We know that our soils contain beneficial bacteria whose function is to protect the plants roots, so they will be stronger and healthier and of course have maximum capacity to absorb the nutrients and fertilizers that we give to our plants. However if we give chlorinated tap water to our plants, the chlorine can kill off the beneficial bacteria present in the soil. This same chlorine, a chemical contaminant, will burn your plants delicate uptake roots, again preventing maximum absorption of needed nutrients.                                                                                                          If we are also purchasing these beneficial bacterias to add to our soils then of course it makes no sense to give our plants chlorinated water. 

The best way to ELIMINATE chlorine is to filter it thru a quality activated carbon or better yet an activated carbon block filter. Carbon filters will also reduce or eliminate other chemical contaminants, such as Gases, Oils, Pesticides and most other Volatile Organic Contaminants (VOC’s).

In answer to the initial question, we definitely do NOT want to water our plants and gardens with chlorinated tap water!

When to use RO water and Why Growers prefer pure water

Many growers worldwide already know of Reverse Osmosis (RO) and the need to achieve pure, contaminant free water for their plants. Whether using soilless, hydroponic systems or traditional gardening with soil, the water we use for our plants is a very important part of growing.

We know that Chlorine can burn our plants roots and also can kill off the beneficial microorganisms present in our soils. Chlorine can be eliminated by using a Activated Carbon Block based FILTER UNIT.

However, a high EC can also be a problem. EC is the measurement of the Dissolved Solids or the dissolved Mineral Content in your water. Too much calcium and magnesium in your water can cause Nutrient Lock Out – where the plants roots are blocked from absorbing necessary nutrients. Other dissolved contaminants; Lead, Cadmium, Boron, Arsenic and other heavy metals can also be toxic for your plants (just like in the human body).

The only way to eliminate Dissolved Solids and lower your EC is with a Reverse Osmosis system. GrowMax Water has engineered a full range of Garden Reverse Osmosis systems, designed with High Flow rates for Growers and easy to install connections for indoor or outdoor installation. GrowMax RO systems will reduce up to 95% of dissolved solids in your water, lowering your EC as well as eliminating your chlorine. This pure water will give you a perfect starting point when you mix and add your essential nutrients for your plants.

When to use Filtration Systems?

We all know that using quality water is important for cultivating and growing our gardens. But all water is not the same quality to begin with. Some water has high EC, some have high iron and manganese content, some well waters are even contaminated with bacteria. However ALL municipal city water does contain chlorine.

Chlorine is a chemical used by cities to kill off possible bacteria in the water and assure that the water is potable or safe to drink. However, as chlorine is a chemical it should then be removed, before drinking. 

The same is true for your plants and gardens. Chlorine is a chemical that must be removed or it will kill the beneficial bacteria present in your soils and also burn your plants uptake roots, limiting the absorption of vital nutrients and essentially slowing your plants growth. 

You do not drink water from your swimming pool nor do you water your plants and gardens with swimming pool water. Chlorine should most definitely be removed from your garden water!

If the EC content of your water is reasonably low and there are no other major contaminant problems with your water, then a FILTER unit is a simple, economical solution for your to eliminate chlorine, a chemical contaminant, from your garden water.

See here the GrowMax Water Filter Line with their high capacity GREEN CARBON BLOCK FILTERS, which will eliminate up to 99.99% of the chlorine present in your water.
