what are the best marijuana seeds for a hydroponics system

A benefit this setup offers is that it can easily be expanded as you want to grow more plants as long as your reservoir has enough capacity to provide all the plants with enough water. To expand a drip line setup, all you need to do is add additional lines to the new pots.

I n the previous post, we gave an overview of hydroponic gardening including its origins, the various systems and techniques, and medium options for a hydroponic grow. In this next article, we will focus how to use hydroponic systems specifically for growing cannabis.

Note what scale the nutrients you are using are based upon before making any nutrient solutions.

The lower the ppm, the less nutrient-dense a solution is. As a general rule, aim for the following densities based on your plant’s age:

The common nickname for cannabis—“weed” —comes from its ability to grow almost anywhere, under varying conditions and different climates. “Hydroponic cannabis” simply refers to plants grown using a nutrient-water solution and an inert growing medium rather than nutrient-rich soil. This method could be something as basic as hand-watering pots of inert medium with a nutrient solution. As discussed in the first part of this series, sophisticated systems with multiple pumps, timers, and reservoirs can take some of the daily labor out of growing, but they require more maintenance and setup time as well as a greater initial investment.

DWC also removes the need to abide by a watering routine. The roots are permanently submerged—free to uptake as much water as they require. Practically any cannabis strain can be used in a DWC grow. However, some varieties are much better suited to this cultivation setup than others. Despite all the benefits of DWC, the lack of soil means there’s nothing to buffer the nutrients, and thus pH fluctuations are more common. As such, strains that can withstand a little bit of “turbulence” are best suited for this method. Check out the 5 best strains to use for DWC below!

Amnesia Haze is a superb option for DWC. She grows to a medium height and can be cultivated with ease in limited space. Expect an indoor yield of around 600g/m² after a flowering period of 12–13 weeks.


DWC is favoured by many cultivators because it’s very low maintenance and can easily be automated using timers, meaning it can be left alone for extended periods without intervention. Plants can also grow extremely large considering a large reservoir is provided. Nutrients are delivered directly to the roots, allowing strains to grow up to several centimetres per day in some cases.

If you’re a fan of body highs and nights spent satisfying the munchies, then try growing Critical via DWC. This indica-dominant strain has been the commercial grower’s go-to cash crop for years. Featuring characteristic hardiness in the grow room, she produces compact buds abundant with gooey, psychoactive resin. Prepare for a long-lasting and intense high that will leave you feeling rested and rejuvenated. If you want to take her strong effect to another level, make some cannabutter and cook up some brownies.

Giant White Haze was born out of an ambitious breeding project involving legendary parent strains Haze and White Widow. This merging was a great success, and the progeny inherited the best traits of both parents. She’s equipped with an invigorating sativa high that sparks creative thoughts and helps the mind to hone in on a single task for long periods. Giant White Haze also offers therapeutic effects to medicinal users in terms of boosting appetite and decreasing anxiety. These effects are augmented by a terpene profile that generates tastes of earth and pine.
