Just because hydroponic grow systems operate without the use of soil, doesn’t mean that your plants don’t need a little assistance. Instead of traditional dirt, hydroponic growers use a number of different mediums to retain water and nutrients in the roots and promote the flow of oxygen. These are the most common mediums for growing weed without soil:
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.
These days, whether in cannabis grow houses or in your garage at home, the same principles apply as they did in ancient history. Simply add nutrients and oxygen to constantly cycling water, remove the soil, then watch your plants flourish.
Growing your own weed has never been easier. Thanks to rapidly expanding legalization laws across the US and the 420-friendly garden supply industry that has sprung up in states that allow home grows, more gardeners are going green than ever before. These days, planting your own pot is more like raising tomatoes than starring in a Breaking Bad sequel.
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.

This is kept on a timer and can be adjusted to suit the needs of the plant.
Lighting systems for hydroponics are pretty similar to any other grow. The only thing to consider is the amount of humidity within the room will probably increase due to water evaporation.
After all of this is done then the plants can finally be added to the set up without issue.
In general, a hydroponic grow won’t differ from a standard grow in most ways, aside from considerations needed to keep the tanks full and the room from getting too wet.

Whether you call it weed, cannabis, pot, marijuana, or something else, the plant known as Cannabis sativa is actually easy to grow at home when you know what you need to do. Growing hydroponically will provide you with higher yields and a shorter grow time compared to growing in soil, but it can often be difficult for the beginning grower to get started with hydroponics. However, most people think of plants growing in water when they think “hydroponics” but actually your plants will get many of the benefits of hydroponics as long as they’re getting their nutrients directly in their water supply. However because of superior air to water ratio in hydroponics, it remains the industry standard. This tutorial will show you step-by-step how to grow your marijuana in 3-4 months using the (arguably) easiest hydroponic method: hand-watering in a soil-less medium.
