Rockwool is another popular choice, and is a substance created using volcanic rocks with a wool texture, hence the name. Rockwool has a tremendous capacity to retain water, which allows for good hydration of the upper root system. Rockwool can be placed within a hydroponic basket, but can also be lodged directly into the top of a bucket or tank lid without.
A drip system in hydroponics is very similar to a drip irrigation system when growing in soil. This system consists of a large tray filled with growing medium, such as clay pebbles. Plants are placed directly into the medium, and each has its own drip pipe nearby. An external water tank with a pump and air stones constantly supplies a drip feed of water over each plant. The roots of these plants are constantly exposed to air, and the excess water drips down the medium and back into the external tank.
If you’re drawn to active hydroponic systems, you have plenty of options to choose from.
As one of the most popular options, clay pebbles are excellent at aerating root systems. Clay pebbles sometimes require that growers alter the pH in order to provide an optimal growing environment, however, pre-altered pebbles can be purchased. You’ll need to place clay pebbles into a plastic hydroponic basket that has spaces for roots to grow through.
Every hydroponic system requires frequent maintenance to provide an optimal growing environment. Below are all of the major factors you need to be aware of.
Aeroponics is perhaps the most futuristic version of hydroponic growing, and uses misted water dispersed through the air to optimise aeration and hydration. Plants are placed into the top of a large tank of water filling the bottom 25%. Under the water is a pump that sends water into misters underneath the root systems. This fine mist constantly soaks the roots, allowing plants to receive massive quantities of air and water simultaneously.
When thinking about hydroponics, you might picture a high-tech setup: automated switches, flashing lights, ticking timers. However, the cost of a hydroponic system all depends on how much money you’re willing to splash. They range from a simple plastic bucket all the way to self-draining and flooding systems. To save time, invest in a cheap hydroponic starter kit. These include all of the materials you need to get from seed to harvest. You can purchase one for around £200 (€235).
GSC is one of California’s most popular strains due to her potency and her classic effect. She is perfect for anyone who’s after a full-body high that leaks nicely into the mind. This strain is ideal for just lounging around like a squishy comfortable lump with snacks and a nice film. Girl Scout Cookies is also known for its visual aspects. The plants turn a lovely dark green with hints of purple and bright orange hairs. The THC level is usually around 18 – 25% with a low CBD level of 0 – 1%. She also produces incredible yields and can get up to 600g/m2 if she is treated well. Again this is a perfect strain for hydroponic growers as she is robust and capable of just doing her thing.
This little lady is another genetic masterpiece perfect for hydroponic growing. She is a combination of Skunk#1 and Afghani, two of the original cannabis strains. Green Crack is a vigorous, high-quality strain that produces impressive yields of powerful buds. Her aroma is a mix of tropical fruit and her flavour is mouth-wateringly sweet with a hint of spice. This is another Sativa dominant strain and her effect is classic Sativa. She is uplifting, euphoric, cerebral, and stimulating. This makes her the ideal strain for creative types or for socialising. Green Crack also came 3rd in the 2011 Treating Yourself Expo Compassion Clubs Cup. She will thrive in a well set up hydroponic system and will usually take around 55 days to flower.
Remember: It is illegal to germinate cannabis seeds in many countries including the UK. It is our duty to inform you of this fact and to urge you to obey all of your local laws to the letter. The Vault only ever sells or sends out seeds for souvenir, collection or novelty purposes.
About Gary Eff
SFV OG Kush is a multi-award winning mega strain that promises fantastic yields from uniform plants. Her awards include 3rd Place Indica at the High Times Amsterdam Awards and 1st Place at the High Times Medical Cup in Denver, both in 2012. This strain does well when she is given a little more time in her harvest. Her plants are known for being easy for new growers due to their uniform nature. They also need very little love and attention to create large yields of top-quality buds. The flavour and scent of the buds are a mix of spice, herbs and lemon. Lineage wise she is a combination of San Fernando Valley OG and Afghani #1. This means that she is a pretty balanced combination of Sativa and Indica. The resulting effect is pleasantly relaxing with a happy little kick. Ideal for chilling and watching a film or just reading in bed.
When we are trying to decide how to grow our crops, one of the most common mistakes is not researching strains. Certain strains do better in certain grow environments than others. For example, one strain that may thrive in a grow room may do poorly outdoors, or another that thrives in a greenhouse will struggle in a hydroponic setup. Today we are talking about the best strains for beginner growers who want to grow hydroponically. Of course, the mear fact that these strains do well in hydroponic setups does not mean they can be popped into the system and left to their own devices. It is still important to research every aspect of growing before getting started.
As always do plenty of research to ensure the best strain is purchased for the chosen growing method.
Sour Diesel is another award-winning strain that is well known for being one of the most potent on the market. She is a balance of Sativa and Indica with an effect to match. She is cerebral but relaxing with an uplifting turn. This means she is often recommended to those who are struggling with depression or stress. Sour Diesel likes a warmer climate and her roots take extremely well to hydroponic systems. She has a surprisingly high CBD content of 1 – 5% which makes her even better suited to medicinal use. The THC is also high at 19%, so she probably shouldn’t be used as a day time medication. Her flavour profile is sweet and sour with a spicy scent that immediately relaxes the brain. Sour Diesel produces good yields and is an ideal strain for those who are just starting out in hydroponic growing.
Most seedling plugs will go back into place easily, and you’ll barely be able to tell it’s been opened ?
Here are tips for taking the best care of hydroponic marijuana seedlings:
Now that your seedling in in the tank, it’s time to learn how to….
Just like in soil or coco, cannabis plants in hydro grow fastest when it’s a little warm, around 75°F!
I’ve seen several growers buy a water chiller and still get root rot. So I personally don’t believe cold temperatures are the best way to go to keep roots healthy.
