How To Grow Weed in Water Using Hydroponics: Grow Weed Without Soil

Hydroponics are one of the best ways to grow plants in water because, unlike soil-based gardening, there are no limitations on what you can grow. Here’s how you can use hydroponics to grow weed in water with ease.

Materials you will need

Step #1: Empty your Solo cup Grease into your Solo cup and set aside. You will now have a small bowl of weed inside your Solo cup Grease. Using your scissor, cut your weed in half and set the lower piece aside for you to smoke later.

Tip: If your weed is ready to smoke, it’s time to pull the bud. You can do this by placing your finger on the bud and slowly turning it until it pops.

Step #3 : Use your small scissors to cut a thin triangle out of the plastic lid of the Solo cup Grease. This makes a hole for your Leaf Cutter to stick in when you later use it to cut your weed down.

All of your growing medium should be pH balanced and you can find this information through your local gardening store or online. You will want to use a 2:1 or 3:1 (water to nutrient) ratio. The pH of your growing medium will be high enough to grow weed without damaging the root system or soil. The best method of applying a nutrient is through a hydroponic drip system. This means that you place a bag of nutrient directly into the water system. You can also mix your nutrient into the water before you place your plant in the water but there is a risk that too much nutrient will get into the water system which would make it less effective for growth.

If you’re using a dedicated glass jar, you can simply fill it up with water and wait for it to completely fill.

M ixes come in varying amounts depending on the size of the plant you want to grow. When you’re ready to start growing plants in water, select a particular nutrient mixture. The quantity will depend on the size of the plant, and you can adjust the amount by using a large or small container.

Put the plant in the jar, cover the top with a lid, and place it in the growing container. You will need to slowly drip the nutrient mixture into the jar.

When using hydroponic gardening you must fertilize and feed your plants regularly. When using soil you only need to fertilize once per month or once per year. You can use the same plant food but in hydroponics it doesn’t last very long and if you don’t use it fast enough it will turn into mold which is not good for your plants. You can also add some nutrients to your water that the plants can eat. Stake plants when growing in your house rather than putting them directly in the water so that you can harvest your plants at the same time. This helps make sure that the plants don’t over grow and that they stay healthy.

Hydroponics: Growing Cannabis Without Soil

If you’re thinking about growing cannabis plants, chances are you’ll think about pots filled with soil. However, in hydroponics, weed is grown in water instead of soil. This technique is also known as hydroculture or RDWC (Recirculating Deep Water Culture), but hydroponics is the most usual term. This method is not as complicated as many people think. Actually, growing gets easier with this technique, as plants will grow faster because they can absorb more nutrients. Hydroponics is suited for just about any plant, but it works especially well with vegetables and cannabis. This blog tells you just what hydroponics can do for you as a cannabis grower.

How Does Hydroponics Work For Cannabis Growers?

To be fair, hydroponics sounds like a pretty impressive technique. The word itself comes from the Greek concepts of ‘hydros’ and ‘ponos’ (‘water-work’; the ancient Greeks worshiped Hydros as an old god of water, and Ponos as the god of hard work). Ironically though, hydroponics done right isn’t hard work at all. Of course, it’s a matter of preference in the end, but most growers agree that hydro grows are easy once you get you get the hang of it.

Hydroponics is on the rise; mostly because it gives growers greater control over how their plants develop. Instead of growing your weed plants in soil, you grow them directly in water containing all necessary nutrients. That comes with some distinct advantages, making this technique an interesting option for advanced and amateur growers alike.

Liquid Lunch: Nutrients Straight From The Water

In hydroponics, plant roots are suspended straight in the water rather than in soil. That makes water the substrate or grow medium. Substrate is just a fancy term for ‘bottom layer’ (‘sub’ + ‘stratum’). Such layers can be anything from sand or rockwool to coco fibre, gravel, or clay pellets. In cannabis hydroponics, water is the grow medium; even if there’s a layer of clay pellets in the top section of a (floating) pot for stability. Nutrients are dissolved into the water and delivered straight to the roots. Any water that is not absorbed is recycled by the system for future use. Roots of plants grown in hydroponics tend to be longer and paler than their soil-grown counterparts, with fewer side branches. This is caused by the low oxygen content of water compared to soil.

Basically, any plant can be grown using hydroponics. Cannabis thrives on it, but these days, you’ll find entire farms growing lettuce and leeks on water alone. Fun fact: the increasing popularity of growing cannabis at home has been one of the driving forces behind the development of new hydroponics systems used in regular agriculture!

Cannabis Hydroponics Basics

The diagram below shows the basic components of a simple hydroponics setup for cannabis growers.

1: Substrate; in this case, water containing nutrients. Some systems have plants suspended directly in water, while other favour pots with a top layer of clay pellets for extra support;

2: Cover preventing evaporation and contamination of the substrate. This is usually a floating lid with holes providing a snug fit for suspended plants;

3: Aeration or oxygenation; usually in the from of an exhaust unit blowing air bubbles into the water;

4: Air pump. Many hydro setups feature a separate water pump with a filter to keep the water clean while circulating.

Different Cannabis Hydroponics Systems

The one thing all hydroponics systems have in common is the lack of soil needed to grow your cannabis plants. Hydroponics gets your cannabis plants everything they need, except light: nutrients, oxygen, and water. This can be done in several ways. Below, you’ll find a summary of the most common hydroponics systems.

(R)DWC: (Recirculating) Deep Water Culture.

(R)DWC: (Recirculating) Deep Water Culture

RDWC is the easiest system to manage, making it a great option for beginners. You put your germinated plants into individual containers, which you then place into a water container. All you add is some hydro pellets to give the roots some added grip. An air pump ensures a constant air supply into the water. Nutrients are added to the water, which the plants can then absorb through their roots. That means roots are constantly exposed to water throughout the growth cycle. The R in RDWC stands for Recirculating, because the water is constantly pumped around the system in a closed loop.

NFT System

This is a slightly more complex system to use. NFT stands for Nutrient Film Technique. Here, plants grow with their roots in a wide tube, usually made of PVC. The oxygen-rich water carrying nutrients is pumped from the reservoir to the tubes and back. Tubes should be installed at an angle to ensure ample water flow back into the reservoir. The ‘Film’ in NFT represents the ideal situation in which just a thin filmy layer of water and nutrients flows over and along the roots.

This system is great at providing nutrients to your plants. If set up efficiently, it also saves water and power. One potential problem is clogged tubing due to roots blocking the flow. That gives bacteria a chance to grow, which of course will negatively impact your plants. Stay sharp while trying NFT!

Ebb And Flow System

In an ebb and flow setup, the roots are not constantly submerged. A pump regularly fills the container with oxygenated and nutrient-rich water. When the container is full, the pump stops working, allowing the water to flow back into the reservoir. It’s a bit like running your own little mangrove at home. You set the ebb and flow intervals according to what your plants need.

Drip System

Drip irrigation is a popular technique among professional growers all across the agri- and horticulture sectors, but amateur homegrowers will find it very convenient, too. You feed and water your plants using a drip system. Every individual plant gets its own drip nozzle. That allows for very accurate distribution of nutrients, ensuring that every plant gets an equal share. Any liquid not absorbed by the plants flows back into the reservoir for future use.

The Benefits Of Cannabis Hydroponics

Compared to growing in soil, hydroponics can have many benefits.

  • You can target your nutrition more accurately, because you don’t depend on what happens to be present in the soil. That allows you to set the perfect nutrient mix without losing valuable ingredients along the way;
  • Save yourself work: no need to remove weeds, while the system makes sure your plants are fed and watered. Just keep an eye on the water level in your reservoir. Two refill a week will usually do the job. As you can see, hydroponics is perfect for lazy relaxed growers;
  • Your plants will absorb the exact amounts of water and nutrients they need; no more and no less. The system simply recycles any excess water, making it a very efficient system too. Obviously, as a plant enthusiast, you care about the environment: life’s good when you can save the world by growing sustainable weed;
  • Pest control: hydroponics environments are cleaner than regular soil. That limits the options for pests and bugs – one thing less to worry about;
  • Better yields: plants grow better in hydroponics. For cannabis, that means better yields than for weed grown in soil, all other factors being equal;
  • Rapid growth: using a hydroponics setup could reduce the growth phase of your plants by three weeks. Roughly speaking, that could mean two extra harvests every year;
  • Not dependent on the weather: hot, dry summer? Freezing cold winter? It’s all the same for hydroponics, because all the plants get exactly what they need, no matter the weather. You don’t even have to keep track of the seasons – if you’re growing indoors, that is.

Drawbacks Of Hydroponics

Using hydroponics for cannabis does come with a few minor drawbacks, though. Firstly, you’ll need to spend more on equipment before you can get your system up and running. Then again, working with the right system eventually pays off in terms of saving on water and electricity.

The second and most important drawback is the tight margin for error that hydro grows offer. Soil has considerable buffer capacity: any surplus of nutrients or lack of oxygen can be compensated in part by the soil and the micro-organisms it contains. Hydroponics barely has any buffer capacity in this sense. Overdosing on nutrients or – worse – power outages will almost certainly damage your plants. That means hydroponics calls for some more vigilance from you as a grower. As long as you know what you’re getting into, though, that should not be a problem.

Outdoor Cannabis Grows Using Hydroponics

Most growers using hydroponics for their cannabis choose to do so indoors. That makes sense from the perspective of optimal control over equipment, lighting, and a bunch of other factors. Such control is slightly trickier to achieve with outdoor grows, but theoretically, hydroponics works perfectly well out in the sunshine. In fact, there are serious plans for using hydroponics as a technique for tackling global hunger issues. Of course, outdoor hydroponics calls for some extra attention to typical open-air factors like the weather, disease, and fungi, but it is certainly an option. A little greenhouse can be a big help, but you don’t strictly need one. What’s more, technology keeps improving all the time, so who knows? You could be running your own water theme park in your back garden come next grow season. At any rate, though, it’s good to know we’ll solve the world’s food problems by the efforts of weed growers such as yourself!

Getting To Grips With Hydroponics

As you’ve seen, cannabis hydroponics opens the door to carefree growing and enjoying better harvests from your weed plants. So, do you feel like starting up your own hydro grow? Give yourself the best possible start with our world-famous cannabis seeds!

Grow your own medical marijuana without soil

Israeli startup Leaf is about to launch pre-sales of a smart home cultivation system as additional US states vote to legalize cannabis.

With seven more US states voting to legalize forms of medical or recreational marijuana use on November 8, the upcoming rollout of the Leaf “plug-n-plant” system for growing the crop at home couldn’t have been better timed.

“It’s an exciting time to launch,” CEO and cofounder Jonathan (Yoni) Ofir tells ISRAEL21c. “We’re seeing a very interesting trend even among traditionally conservative states, and it could be the beginning of the end of the federal ban on cannabis. From an industry perspective, this makes our product even more appealing to entrepreneurs and investors.”

Leaf looks like a small refrigerator (2 feet by 4 feet) but it’s actually a sophisticated automatic cannabis-cultivation system.

“On average you will yield 4 ounces of high-quality, pesticide-free medicine every three months,” says Ofir. “Our beta testers have grown almost double that in certain cases.”

You don’t need pots, soil or even a green thumb. Water, light, acidity, temperature, humidity and nutrients all are monitored by sensors and controlled by a smartphone app. The system dries the leaves at the end of the grow cycle so they’re fully ready for consumption.

An embedded HD camera provides a live stream of images during the process for users to share via the app, which also offers explanatory video clips.

The Leaf system is available online in the near future at a preorder price of $2,990 through early 2017, for shipping next September. A $300 deposit is required; the balance will be collected at time of shipment and the deposit can be refunded up until that time.

“Initially we will be shipping to the USA and Canada,” says Ofir. “We are currently working on international distribution partnerships to be able to ship worldwide.”

Leaf will realize additional revenues from renewables: carbon filters to keep odors from escaping the unit, and disposable nutrient pods from Advanced Nutrients, one of Leaf’s strategic investors. The pods fit into the machine like ink cartridges in a printer.

Market opportunity

Ofir was born to Israeli parents in California, where marijuana was legalized for medical use in 1996 and is now approved for recreational use as well. The family moved back to Israel in 2000, when he was 11.

His previous startup, Alcohoot, invented a smartphone breathalyzer and was sold to an American company a couple of years ago. That freed up Ofir to work on another project.

“I had a [medical marijuana] growing license and I realized there were a lot of things I could automate about the process, so I started building the Leaf prototype for myself,” he relates. “Many people were interested in it and we recognized a market opportunity. That’s how we started and it’s taken off from there.”

Ofir and cofounder Eran Mordechay, Leaf’s CTO, raised $2 million in their first funding round after establishing the company last year.

Leaf has about 20 employees, including five horticulturalists doing growth and nutrient testing in the company headquarters outside Boulder, Colorado, where growing cannabis is legal. “We plan to expand that office tremendously as we start sales and customer service,” says Ofir.

All research and development activities are based in Tel Aviv. Ofir says this is where he and Mordechay had all the agricultural, engineering, industrial design and medical research resources they needed. Israel is renowned for advanced cannabis research.

“It was extremely easy to recruit top-tier employees who are really passionate about what we’re doing,” Ofir tells ISRAEL21c.

“We always had a scientific approach and our product has been built to be a sort of lab tool where you can change parameters to create the very best medicine for yourself, chemical- and pesticide-free.”

As the shifting winds in the United States attest, growing cannabis is no longer about counterculture hippies or fringe medical practitioners.

“The one commonality in Leaf’s market is people who use cannabis on a regular basis, but besides that it spans across every age group, gender and profession,” says Ofir.

Update: Some 1,500 units of the Leaf system, sold for $3,000 apiece, were ready for shipping in spring 2018.
