The cheapest and most simplistic system to set up at home, Deep Water Culture grows are often the easiest way to grow hydroponic weed on your own at home. Consisting of a grow tray that houseshousing individually potted plants suspended in your chosen medium, the system uses a drip line of nutrient-rich, oxygenated water to circulate plant food from a larger reservoir tank. Because each grow pot has holes in the bottom, the water is eventually filtered out of the roots and growing medium and then carried by another hose back to the reservoir, where it is eventually recycled. As long as proper amounts of nutrients and oxygen are added and the water is able to cycle freely, your pot plants will thrive in a DWC system.
In an attempt to replicate the natural movement of the tides, Ebb and Flow hydroponic systems use intervals of soaking and draining to feed and water the plants instead of a steady stream of flowing water. Using the same reservoir and grow tray separation, the Ebb and Flow system operates in cycles of all-or-nothing feeding. This results in a flooding of the plant and its roots with nutrient-rich oxygenated water for an extended period. Eventually, it will use gravity to drain, giving the plant maximum amounts of oxygen before the water is recycled and the plant soaked again the next day.
A slightly more complex version of the Deep Water Culture, the Nutrient Film Technique typically uses a tilted round PVC tube with holes drilled in to house each plant. Nutrient-rich oxygenated water is then pumped from a reservoir tank into the top of the PVC pipe, where it then flows down the tube, passing by all of the roots before it is funnelled back into the reservoir.
How to Grow Hydroponic Weed
Made from ultra-thin threads of processed rock, Rockwool is another useful tool for growing weed in water. Like clay pellets, Rockwool is great at retaining water while providing enough room for oxygen flow, making it a perfect and long-trusted replacement for soil for growing weed. Unlike clay pellets though, Rockwool must first be PH treated before it can properly house pot plants which, adding an extra layer of labor to the hydroponic process.
An all-natural medium for plants that grow without soil, shredded coconut fibers let in more oxygen and retain more water than rock or clay. As a result, coconut fibers are yet another trusted method for how to grow weed in water.
Once you decide to delve into homebound horticulture, you’ll find there are a plethora of different ways to grow weed. Whether you’re indoors, outside, or in a greenhouse, there are many options you can use to go from seedling to full-flowering bud. While weed is traditionally grown with dirt, water, and sunshine, today we’ll be leaving the soil at the garden store and diving into the world of hydroponics.
Clay is one of the most popular mediums used to grow weed in water. In pellet form, clay is able to cradle the plant while retaining nutrient-rich water for the roots while still allowing enough oxygen flow to let the plant breathe.
To reduce the cost of your ventilation system, make sure you buy an extractor fan with a m³/h rating that will ensure the correct air circulation. m³/h (cubic metre per hour) is an indicator of how much air an extractor can pull out of a space every hour. For proper ventilation, you’ll want to invest in a fan with a m³/h 70 times higher than the volume of your room/tent. This is because the average number of air exchanges required in a grow room is around 70 per hour.
The cost of buying new seeds after every harvest can add up, especially if you’ve got a big garden and grow several plants at a time. Cloning can offset some of those costs, giving you the opportunity to reproduce your favourite strains without having to invest in new seeds every time.
When you buy seeds from a respected seed bank, you’re paying for guaranteed quality. Established seed banks have teams of dedicated breeders and growers constantly working to improve their genetics. That means, after germinating your seeds, you can rest assured the plants in your garden will grow strong and healthy (given the right care, of course) and reward you with good yields of top-shelf bud.
Utilise the Right Lighting
Note that, over time, the yield potential of mother plants tends to go down. To deal with this, most growers renew their mother plants every 6–12 months. In general, we recommend buying seeds, keeping the healthiest plant from your seeds as a mother, and cloning it for 6 months before repeating the process. This will help ensure you’re always working with healthy plants.
Ventilation is something growers shouldn’t skimp on, regardless of their budget. Extractor fans help pull old, stale air out of your room/tent so it can be replaced with fresh, oxygen-rich air from outside, while oscillating fans help keep air moving throughout your grow room. Both are super important for supporting the growth of your plants and keeping your room/tent free of pests and pathogens.
Growing cannabis doesn’t have to be a huge investment. With the right tips, you can reduce the cost of your cannabis grow room/garden and grow top-shelf weed on a budget.
While LED lights come at a higher outright cost than HID lights, they are much more efficient and cheaper to run, making them more cost-effective in the long-term. Not only that, but LEDs tend to run much cooler than HIDs, which is an important factor given the spatial limitations of most indoor budget growers.
RDWC System without plants.
How about running your personal mangrove at home?
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.
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!
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!
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.
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.
