What is the best type of hydroponics systems?

This is an entirely subjective choice as each grower will prefer a different set-up and have different requirements (i.e. number of plants, height of system, or budget). Hydroponics at home would be a very different system than a Commercial Greenhouse System. Different types of hydroponic systems can range from; Aeroponics, Aquaponics, Deep Water Culture, Drip System, Ebb & Flow, NFT, and Wick. The 3 things all hydroponic systems have in common are the plant roots need for water, oxygen, and nutrients. The best hydroponic system to buy, is the one that suits you best! Call us at (888)464-1849 to discuss your grow requirements.

Is growing in hydroponics easy?

There are hydroponic systems tailored to every level of ability, each one capable of delivering great results. Deep Water Culture seems to be one of the easiest, most forgiving ways to learn how to grow hydroponics for beginners. The Gro Momma DWC Kit is an affordable solution we recommend to beginners growing hydroponics.

Lighting

What's the best lamp to use for vegetative growth?

For early vegetative growth, fluorescent tubes work well. However if you can afford LED grow lights your plants will thank you. Light loving plants need more light progressively as they get bigger, LED’s can provide a full spectrum of light and keep the heat down. Read more about choosing the right lights to grow plants indoors.

What are the benefits of Light Movers for Grow Lights?

Your garden can be made larger using the same amount of light and electricity effectively increasing your yield per watt. Light Rails also help to avoid hot spots on the leaves, nobody likes a sunburn. Moving your grow lights back-and-forth can make them much more efficient providing more light coverage on your plants. Shop our Light Movers section for different Light Rail options, also check out the Gualala Robotics - Light Rail website to understand all the benefits of moving your grow lights.

How often should I change my bulbs?

For HPS and Metal Halide lamps, you should change your lamp at least every 9 months. This is because the performance of your bulbs steadily diminishes from three weeks after initial firing. From this point it is a straight line down in terms of performance versus time. Due to the low price of lamps these days, you often lose more yield than the cost of a new lamp if you leave replacement longer than this. Double Ended Grow Lights last a little bit longer and should be changed every 12 months.

What's the best medium for flood & drain?

Debatable. There are a handful of factors involved in choosing the right media for your plants. Depending on the type of hydroponic system you are using and the type of plant you are growing. Rockwool, Coco Coir and Clay Pebbles all work very well. Experiment and find out what works best for your plant’s set-up.

Are grow lights safe?

Very, as long as you buy from a reputable retailer and use a timer unit where applicable. Bear in mind that with HID lighting the lamps become very hot when in use, so you’ll want to duct in enough cool air to keep the tent or grow room safe.

What's the ideal temperature for my grow room?

When your lights are on, the ideal temperature for your grow room should be 75º-80º degrees Fahrenheit for most light loving plants. When the lights are off, the temperature should be between 70º-75º Fahrenheit.

I’ve seen it mentioned that you should use ventilation in indoor growing areas where HID lights are used, why is this?

Remember, temperatures between 70º-85º Fahrenheit are what most plants prefer. If you use HID lights in confined spaces heat build up can be a problem, especially with 600W versions and above. In this case it makes sense to use a small extractor fan of some kind to remove some of the hot air and keep the air in the area fresh and full of CO2, this can become depleted quite quickly in indoor growing areas. Experienced growers usually build a sealed grow room and use air conditioners. Shop our extensive environment section to find the best option to suit your needs.

What is Ebb & Flow?

Sometimes known as flood & drain, ebb & flow systems periodically flood the entire root zone with nutrient solution before it dries out. This is done with a timer on a pump from a main nutrient tank usually located directly below the flood tray. The root zone is flooded for short periods of time (between 10-15 minutes). The interval between floods will depend on plant size and medium used (rockwool or expanded clay pebbles).

What is a Run-to-Waste system?

As opposed to a recirculating system, run-to-waste systems do not run the nutrient solution back to a main tank after circulation. The nutrient solution is used once and collected in a separate tank never to be used again. 10% run-off (the amount of waste nutrient in comparison with your start quantity) is sufficient for good results. Try to keep your waste to minimum. In third world countries, run-to-waste systems where no run off waste is achieved are very popular for water conservation.

What is a recirculating system?

As opposed to a run-to-waste system, the nutrient solution is returned to a main nutrient tank for re-circulation.

Environmental

My growroom smells what should I do?

We recommend carbon filters for complete odor elimination. These connect to the air extraction system in your grow room. We also sell ozonators, air purifiers and odor removing gels. Contact EastWestHydro customer service for further advice on size requirements and installation.

How often does my carbon filter need changing?

Most manufacturers say Carbon Filters generally last at least 18 months depending on the amount of hours it has been used. Most of the larger sizes will last at least 24 months. You can help extend the longevity of your air filter by pairing it with the proper Pre-Filter. This will help keep larger dust particles out of your Carbon Filter.

Should I use Mylar or Black & White sheeting?

Both have very high light reflective properties. Mylar reflects more light but also reflects more heat as it is ultimately a heat reflective material with up to 97% heat reflection. Therefore Mylar can be a problem in small grow rooms without good air exchange making them a bit too hot in summer. Reflective Films come in all sorts of thicknesses and sizes depending on your growing needs.

Do I need an input fan on my grow room?

In a one light situation with one extractor, an input fan is generally not required. In a two or more light situation, it is usually of benefit to install an input fan as it will help cool your room, although this is not always essential. It really just depends on how hot your room is getting.

Is air movement necessary in my grow room?

Short answer is, yes. Oscillating Fans are one of the most efficient ways to circulate the air in your grow room or grow tent. Stagnant air can tend to attract anaerobic molds, so the breeze from a wall mounted or floor fan is definitely beneficial for developing plants.

Can you tell me how to quiet my extraction system?

Acoustic ducting is available and will significantly reduce the noise made by the air entering and leaving the fan which is the primary source of noise with most fans. Duct Silencers are also effective at reducing noise in larger rooms, stealth fans rubber mounted inside silencing canisters and lightweight acoustic foam are also available.

Cultivation

What is cloning?

Cloning is a form of plant propagation that has been around for a very long time. It's basically taking a growing portion of a plant - a stem with some leaves attached, and helping it to become a brand new plant that is genetically identical to the plant from which the clone was taken. This is often easy to do because plants often clone themselves in nature. It's called asexual reproduction. The methods currently used today include taking cuttings, layering, division, grafting, budding and tissue culture. Gardeners often trade cuttings and divisions as a way of sharing plants with their friends.

What are cuttings?

A stem cutting is a terminal growing point on a plant. It is 4 to 6 inches long and is cut off at a node. A node is the point on a stem where a leaf is attached. The bottom leaves are removed from the nodes and the lower end is inserted into the rooting medium. Some plants are excellent material for cuttings; others never survive. Both woody and herbaceous plants may be used for cutting materials.

What's the best medium for rooting cuttings?

Small rockwool cubes or natural soil-less grow plugs are the most popular medium as they tend to give the best results. Other mediums can be experimented with such as coco coir in net baskets in an attempt to reduce rooting time by using a looser medium.

Can all plants be cloned?

Most plants can be cloned, although it takes different methods to do so. The kind of cloning performed most often in greenhouse situations is to take cuttings.

Do I need a propagator to start my cuttings?

Yes. You will have too many problems maintaining a high humidity without one. Start your cuttings with this propagation kit or something similar.

Do I need a propagator to start my seeds?

A propagator is only needed to crack the seed shell. Once the tap root emerges from the crack, they can be put straight under the light in cubes or pots. Cracking the shell may alternatively be done on tissue paper negating the need for a propagator.

How much light do I need to root my cuttings?

A fluorescent tube or two is generally all that is required over a propagator. This is ideal as the cuttings will not get too hot and they provide enough light to root all cuttings. Too much light when the cuttings have no roots will force them to keel over in the propagator.

Can I root my cuttings in grow plugs and then plant into soil?

Once cuttings are rooted in the plugs, they can generally be transplanted into almost anything or any kind of system, including directly into a pot of soil.

What temperature should I keep my clones at?

Keep plant clones in a well-ventilated, cool location. The temperatures should be about 70º to 75ºF in the air around the plants, but the bottom heat from the heat mat should be supplying heat of about 80ºF. Bottom heat from a heat mat encourages root growth. The humidity level should be kept at or near 90%. These conditions encourage compact, but dense growth.

Nutrient & Management

How do I know whether to use hard or soft water feed?

Officially, hard water is anything over pH 7. In practical terms, for growing plants hydroponically hard water feeds should only be used for very hard water generally with a pH above 7.8 and a cF value above 8-9. Soft water feed should be used in all other cases and the water will need to be pH adjusted with either nitric or phosphoric acid.

Why do I need to test my pH?

When growing hydroponically, the nutrients are more available to the plants if the pH is between a range of 5.5 - 6.5. Your roots will thrive within the pH range of 5.5 - 6.5, so testing your pH to find out if your water is acidic, alkaline or neutral is a must.

How do I test and adjust my pH?

Electronic pH pens are available to help calibrate your pH levels. Many people still like to use manual indicator kits which are easy to use and foolproof. These kits are are the cheaper option. Water should be de-chlorinated (left to stand to allow the chlorine to evaporate) for 12 hours before testing. For more options shop our pH Pens for sale.

Do I need to adjust my pH for my soil garden?

The nutrient availability in a soil environment is much larger that pH adjustment is not necessary. We sell many soils and growing mixes that can improve your growing success. Soil Mixes combine many ingredients such as; Composted Material, Perlite, Coco Coir, Pumice, Peat Moss, Bat Guano, Worm Castings, and more.

Should I use Nitric acid or Phosphoric acid for adjusting my pH?

This is your choice. It's just another option for you. Generally, Nitric acid is used in the vegetative stage and phosphoric in the flowering stage.

How often should I change my nutrient solution in my hydroponic system?

When the plants are young, every two weeks should suffice. With small nutrient tanks you may want to do it more often. When the plants are bigger, (eating and drinking more) it's best to change the solution every week to ensure optimum results.

Should I adjust my pH every day?

In recirculating systems (NFT, Flood & Drain) the pH will fluctuate on a daily basis. This is normal. Do not adjust the pH every day, rather every two or three days to avoid build-up of phosphoric acid in the system.

What is the best way of introducing oxygen?

Air pumps and air stones are good ways of introducing oxygen into your water. Use of air stones will also help keep the nutrient solution moving maintaining consistency and reducing stagnant water.

Do I need an air stone in my nutrient tank?

Most good hydroponic systems maintain enough oxygen content in the nutrient solution due to their design. This makes addition of air stones non-essential although they can be beneficial in keeping the solution moving at times when it is not in circulation around your system. This keeps the solution evenly mixed and always well aerated.

Plant Health

My leaves are curling up. What's happening and how can I stop this?

Leaves curl up at the margin and tip in an attempt to retain water. If they are curling up, this would indicate slight environmental problem: Either your light is a little too close to the plant or your oscillating fans are drawing too much moisture from the leaves. To remedy this problem, move your light up and make sure oscillating fans are not blowing too heavily on the leaves.

My leaves are curling down. What's happening and how can I stop this?

Similarly to upwards leaf curling, the plant is trying to retain moisture by reducing its leaf surface area. A downward curl would indicate that your nutrient solution is too strong. To remedy this problem, reduce feed strength, move your light up and make sure oscillating fans are not blowing too heavily on the leaves.

My big bottom leaves are losing color. What's wrong, and how can I stop this?

This would be quite normal in a high light situation. The large leaves at the bottom of the plant will lose color as they get old and younger leaves nearer the light will take over as the main leaf engines of the plant.

I have rusty spots/marks and light coloring on my leaves. What is wrong?

Check for bugs, especially on the undersides of the leaves. If no bugs are present it could be an environmental or nutrient problem. Take immediate demands off the plant (move light up, check nutrient strengths, and pH.

My new shoots are all light colored. Is this a problem?

It could be. Check your nutrient solution or make a new solution. If this is OK your light may be too close or your night temperature too cold.

My plants have died. What should I do?

Listen to this song and cry yourself to sleep.
