- Basic Plant Biology1:44The roots stems and leaves of flowering plants are functionally connected through cells called xylem and phloem. Xylem cells are responsible for the uptake and distribution of water and dissolved nutrients. Phloem cells distribute photo synthetically produced sugars and various other compounds to ac…
- Factors that Maximize Yield9:44The four most important factors that go into maximum yield are as follows in order of importance: Genetics Often overlooked, it important to realize that genetics is the number one factor in obtaining maximum yield. As in raising any living organism, the genetic foundation is everything. The reason…
- Nutrient Salts and PPM (Parts per Million)5:21According to science there are 16 essential plant nutrients. These are divided into two groups: Macronutrients - carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, sulfur and magnesium are required in large amounts. Micronutrients – iron, chlorine, manganese, boron, zinc, copper an…
- pH and Plants2:03pH is a scale of 0-14 which measures the acidity or alkalinity of a nutrient solution. This scale can be measured by its concentration of hydrogen ions. Pure water is neutral, neither acidic nor alkaline (it has the same number of positive charges (H+) as negative charges (OH-) which is a pH of 7. T…
- Irrigation Principles8:21Hydroponic gardens offer the root zone water without having to expend energy to look for nutrients or oxygen over larger areas. Due to the high availability of water this can cause the plant cells to swell giving the impression of a larger plant. This will also increase the fresh weight of a yield;…
- Quick Reference1:38Lighting Lights should not be closer than 18 inches unless air cooled Lights on temp 80-85 degrees F Lights off temp 70 degrees F 10-15 degree differential between lights on and lights off temp Humidity Humidity 50 –60 % 60% in vegetative growth is ideal 50% in flower 45% in flower if strain tends t…
- Mediums5:46RockWool Rock wool is the most widely used medium for hydroponic gardening in the world. Rock wool is an inert fibrous medium produced from a mixture of volcanic rock, limestone, and coke, melted at 1500 to 2000 degrees Celsius. The fine threads are pressed into woven sheets. Rock wool is slightly a…
- Common Hydroponic Systems6:04Drip Systems When running these types of systems it is important to keep the root zone moist, this does not require as much water as it appears. It is not necessary to run a continuous open flow of water through the root zone. This will actually limit growth as the root zone will always be covered w…
- Dirt Gardens6:59What is typically called a dirt garden is not true soil. Peat and perlite are hydroponic mediums. Contrary to popular belief the yield and quality can be just as good. A dirt garden can be easier to manage for beginners granted they have the proper tutelage. If there is a large investment involved a…
- Alternative Hydroponic Systems3:10Aeroponics Aeroponics consists of misting the roots to maintain adequate moisture levels and deliver nutrient. There are many advantages in the use of aeroponics systems. As we have learned oxygen accounts for 45% of dry plant matter, the more oxygen we can deliver to the root zone the more root mas…
- Starting from Seed4:14Starting a plant from seed will not only produce a genetically fresh specimen it will also, if done correctly, ensure that the stock is disease free. Some gardeners neglect to see the importance of taking their favorite strain back to seed every few years. This can lead to a genetically tired plant.…
- Mothers and Clones10:44Producing plants by cloning is by far the most common and favored method of propagation as it is the quickest. Plants that have been cloned are already genetically mature; this enables a gardener to induce flowering with reasonable assurance that the plant will respond consistently. Due to the head…
- Pruning, Topping, & Bending3:45Pruning is often a controversial topic even though it need not be. A basic understanding of how plant hormones regulate growth in plants will give us the tools to understand how and when to prune. As we know auxins are primarily located in the apical bud (the growing tip) if we remove this growing t…
- Setting Up the Garden6:01Thorough planning is required in setting up any garden, and each one is usually tailored to the particular circumstances of the gardener. There is no absolute right way; there are many ways that will provide a beneficial environment. There are, however, basic pointers that when followed can save a w…
- Climate Control8:46The reason that plants produce a premium crop indoors is due to the consistency of the environment. Plants love consistency. Consistency is achieved by using environmental controls to monitor the environment and maintain the parameters that have been set. The optimum environment is 80-85F lights on,…
- Lighting2:37Lights HID lighting consists of metal halide lighting and high pressure sodium lighting. Each type of HID lighting is available in different wattages. It is necessary to match the correct ballast with the correct bulb (recent developments in electronic ballasts are offering units capable of running…
- CO27:20Carbon Dioxide (CO2) is processed into 45% of dry plant matter thus comprising half of our yield. CO2 is an absolutely necessary component of the process of photosynthesis. Without adequate CO2 to process water, light and nutrient, the light will literally bounce off of your plant. This makes CO2 on…
- Odor Control3:57The main methods of odor control are ozone generators and charcoal filters. Charcoal filters have definitely become the preferred choice in odor control as they do not break down and do not produce an alternate odor such as ozone which is easily recognizable. Charcoal filters are best placed before…
- Harvest Time1:41It is very important that the crop is flushed for 7 days with a flushing agent, or 10 to 14 days with straight water prior to harvest. Misting plants with straight water is what is termed reverse foliar feeding and will have the effect of leaching out the excess nitrogen. If your plant is turning ye…
- Integrated Pest Management (IPM)9:30Integrated pest management (IPM) is a method of preventing pest problems while utilizing the least-toxic controls. The first step is to correctly identify your pest, however, there are some control methods that may be used whether a pest is present or not. The term pest may refer to any living organ…
- Mites, Gnats, Thrips, and Aphids6:13Spider Mites Spider mites will be found on the undersides of the leaves. The attentive gardener will make a habit of inspecting the crop for infestation on a regular basis. Spider mites like it hot and dry. The ideal environment for the two spotted mite is 85-90F and 50% humidity or lower. These env…
- Powdery Mildew, Rust, Root Disease5:18Powdery Mildew To date there are thirteen different strains of powdery mildew some like to be dry, some like to be wet. The most common one in indoor gardens likes a hot and dry environment. Earliest signs will be a round white patch starting on the top of the leaf. Left unchecked it can cover the l…
- Bleaching, Wilting, Yellowing, Curling, Stretching, and Slow Growth4:26Bleaching Sun scald will actually bleach plant matter turning it white. Flowers that are too close to the bulbs will exhibit retarded growth and/or dry out becoming dead and crumbly. 1000 watt Lights should not be closer than 18 inches unless they are air-cooled adequately. Yellowing Sometimes a pla…
- Nutrient and Chemical Problems2:13Nutrient and other types of burns • • • • Nutrient burn tends to appear as browning on the tips of the leaves, this is usually due to overfeeding or possibly a nutrient solution that was not topped up with water and became too concentrated. The bottom third of the root zone is the eating and drinkin…
- Hormones3:48Plants are what is termed totipotent. Each plant cell contains the genetic information to form a complete plant; however, plant cells require external signals to regulate growth. Plant hormones are responsible for providing the plant with these signals. Responses in plants that hormones initiate are…
- Organic Hydroponics10:08During a day and age when our environment is becoming increasingly toxic, including the air we breathe, the water we drink, and the food we eat, moreand more of us are turning to the natural alternatives that are available. We are starting to consider how future generations may be affected by the po…
- Outdoor Considerations3:07With the boundless candle power of the sun if you can find the right location harvesting a crop from a well tended outdoor garden can be like winning the lottery. It is important that the outdoor grower understand the climate of the region to be cultivated in. Good quality strains that have a histor…
