What is hydroponics?

Hydroponics is growing plants without soil.  Anything that can be grown in soil can be grown with hydroponics. The key is supplying the correct nutrient solution for the specific plant, and constantly supplying it to the roots. Typically, by using hydroponic nutrients, plants will outperform soil grown plants in the same environment. Hydroponic systems use artifical lighting to mimic the effects of the sun.

Hydroponic Systems Explained. 

Nutrient Film Technique, NFT

This is the original hydroponic technique very popular with indoor gardeners due to the simplicity and amazing results achieved. The princible is very simple, the plants are grown in a constant flow of nutrient enriched water. The water is spread out as to flow 1-4mm of depth over a flat surface. This creates a film of water which flows over the roots of the plant. Water is fed to the table via a submersible pump from the top end of the table. The table is set at a slight angle to aid the flow of the nutrient enriched water down the table and back into the nutrient reservoir and re circulated back over the plants root system.

Ebb and Flood Hydroponics

This is a very straight foward and effective form of hydroponic gardening. The ebb and flood system usually use clay pebbles as the grow medium as this provides good drainage and retention of water. An ebb and flood hydoponic system typically works by using a timer and a submersible pump. The timer controls the flood and drain cycles which over a period of preset times floods the growing medium with nutrient enriched water, then when the desired level is reached the pump stops and the water is drained back into the nutrient reservoir.This cycle is then repeated when the medium becomes dry.

Aeroponics

The principle of aeroponics works by using a fine mist of nutrient enriched water sprayed inside a container  where the roots of the plants are suspended. So the roots are hanging in the air supported by a net pot with Clay pebbles or Rockwool cube. The roots are then constantly misted using a pump. This technique allows for the roots to absorb high levels of oxygen and nutrients resulting in amazing growth rates. 

Hydroponic Dripper Systems

Plants are individually fed using dripper pipes. These drippers are set to deliver a set amount of water per hour. Every dripper is linked to a delivery tube which is fed via a pump in the nutrient reservoir. The systems can be run to waste or recirculated via a nutrient reservoir.

Deep Water Culture, DWC or Bubbler

The most basic method of hydroponic growing usually used by growers who wish to grow only a couple of plants. The system consists of a container with a lid, net pot, clay pebbles, air pump and air stone. The air stone is placed at the bottom of the container and linked to the air pump. The container is then filled with nutrient enriched water. The lid is then placed on top of the container which holds the net pot which contains the clay pebble grow medium. The system uses the air stone to release oxygen through the nutrient solution to feed the plants roots constantly.

Soil Grown

The soil used should always be of high quality like Biobizz All Mix. Take your newley rooted cutting or seed and place the rockwool cube or jiffy plug into a 5 Inch small pot this will enable the plant to build a good root system over approximately 3 weeks. Start to feed your plants with nutrient enriched water after 3 weeks as All Mix contains enough nutrients to get you to this point. Then transplant to the final pot 11ltr for small to medium sized plants 16ltr pots to larger or longer finishing plants. Water your plants from the top and allow a little run off from the bottom of the pot. Do not leave your plants standing in water as this will cause health problems for the plant. There is no need to PH adjust the nutrient solution in soil as it acts as a buffer.

Hydroponic Lighting Options Explained

Metal Halide Lamps

Metal Halide lights are the most effective and efficient form of white light available to the hydroponic gardener. Available in 250, 400, 600 and 1000watt. Metal Halides should be used during the vegative stage of a plants life. These lamps should be replaced every 4 to 6 months as the amount of lumens they produce will decline over the lamps life.

High Pressure Sodium Lamps, HPS

HPS Lamps are the most popular type of light used by hydroponic gardeners. Available in 250, 400, 600 and 1000watt. HPS lamps are great for flowering plants because they produce an orange yellow glow that is similar to that of the setting sun in the summer time which is just the right spectrum for flowering plants.These lamps should be replaced every 4 to 6 months as the amount of lumens they produce will decline over the lamps life.

Fluorescent Lamps, CFL

CFLs produce a good spectrum of light however the lumen output is not as good as HPS or Metal halide lamps. CFLs are great lights for raising seedlings or getting cuttings to root.

Basically light is food for plants everything we give the plant assists the plant to utilise the light. More light equals larger yields. Lamp heights can vary up and down depending on seasons, plant species, and growing method hydroponics or pot culture. CFLs should be approximately 15cm above plant tops. HPS and Metal Halide Lamps produce quite a lot of heat so 250w lamps should be at least 50cm distance from plant tops, 400w should be around 60cm, 600w should be about 70cm a quick tip if its to hot for the back of your hand its to hot for your plants.

Oxygen and Air Supply Explained.

One of the most overlooked factors in hydroponic indoor gardening. Air circulation and ventilation are vital for healthy plant growth. Your grow rooms air should be changed at a rate of 20 times an hour. If you are not sure what size extractor fan to use, it's easy to work out. Simply calculate the volume of the growing environment to the nearest cubic metre. This is done by multiplying: Length x Width x Height = Volume of your room in cubic metres (m³) and then multiply the answer by 20. Therefore, just multiply the volume of your growroom by 20. For example, a room of 3 metres x 4 metres x 2.5 metres high = 30m³ and 30m³ x 20 changes per hour = 600m³ per hour. Once this has been calculated, you can select the correct fan. Intake fans should be 20% - 50% smaller than your extractor fan, to ensure a positive flow rate through your grow room which will ensure no bad odours are forced out of the grow room and are only vented out via your filtration system.

Water PH Explained.

PH is a way of measuring your waters alkalinity or acidity. The measure reads from 0 to 14, 0 is the most acidic and 14 the most alkalinic and 7 being neutral. Plants can only up take nutrients if the PH level is correct. The range is between 6 and 7 when growing in soil, or 5.5 to 6.5 for most hydroponic systems. Most hydroponic mediums will have to be PH adjusted according to the medium being used i.e. Rockwool has a higher alkalinity to Clay pebbles so will need adjusting accordingly. This can be done by using PH up or PH down solutions. Regular checking of your nutrient reservoir should be done by using a PH kit or PH meter.

Nutrients Explained.

Nutrient solutions come in all different variations however they are all based on the same theme. They are differing variants of (N)Nitrogen (P)Phosphorus (K)Potassium. Nitrogen is used by the plant in higher amounts during the vegative stage of its life. Phosphorus is used at the germination, veg stage and in higher amounts during flowering stage, Flower boost nutrient solutions like Dutch Pro Explode will contain high levels of Phosporus creating explosive flowering patterns. Potassium is used by the plant during all stages of its growing cycles and it encourages strong root growth increased water intake and increased resistance to disease aswell as increasing the plants chlorophyll which helps the plant to use the lights energy to its full potential.

Temperatures and Humidity Explained. 

Most plants like temperatures to be about 75F with humidity of around 50%. It is also recommended that day and night temperature should be similar around 10F less at night. This ensures the plants are not caused any stress which will effect your yields. A Hygrometer and thermometer are essentials in your grow room.

CO2 Enrichment Explained.

Carbon Dioxide has been used in commercial greenhouses for years. Enriching your grow room with CO2 will stimulate plant growth. If you get the enviromental conditions correct and are enriching the grow area with CO2 you can almost double a plants growth. CO2 fed plants use more water and nutrients and require a bit more maintenance than non enriched plants. The temperature of the grow area can also be increased if using CO2.

Pests Control Explained.

Basic precautions for your grow room are to keep the room clean and free from smells, dead plant material and bacteria. Make sure your room has good air movement and intake fans are fitted with a filter like the odorsok. Put any new plants in a different area untill your sure they are pest free. Only buy high quality grow mediums and soils. Keep pets away from the grow area. Change your clothes before going into your grow area to be sure you dont carry any pests in and do a 7 day pest check. This involves checking for any leaf damage. Spider mites will go from egg to an egg laying adult in just 5 days, they are capable of destroying a crop. Spider mite will leave clusters of white dots on the leaf, if found remove the infected leaves straight into a bag, then spray the infected plants with one of our pesticides and continue to spray every 3 to 5 days or as instructed.
