Growing in coco coir can be considered a type of hydroponics since it naturally contains no nutrients and you must provide all the nutrients in the water. However, when you say “hydroponics” most people think of this:

Before you get started, you’ll need to gather the following supplies:
Monitoring: Part of the time investment involves near-constant monitoring of the garden to ensure the health of the plants. If one cannabis plant in a hydroponics system becomes diseased, the entire crop may fail and die. Damaging microorganisms also thrive in wet environments and could threaten the health of the plants before harvest time.

Potency: Once you harvest the buds, there’s a good chance they’ll be more potent than if you had grown them in soil. Some dispensaries even charge a premium for buds grown in hydroponic systems.
How do you grow hydroponics at home?
Hydroponic growing is a horticultural method for growing crops, including cannabis, without the use of soil. In place of soil, growers use a mineral nutrient solution in a water-based solvent. Occasionally, growers may also use clay pebbles and sand.
For outdoor growing at home, a sunlit patio or deck make ideal locations. But if you live in a cold climate, it would be better to keep your hydroponic cannabis garden inside. Otherwise, the plants will be subjected to the elements and vital water could evaporate if you do not consistently monitor nutrient solution levels.
Space saving: A hydroponics system is a major space saver that may require 20% less room than soil cultivation.
What are the benefits of hydroponic growing?
A dedicated space indoors is the best location to grow hydroponics at home. In addition to the hydroponics system, you can furnish your garden with supplemental grow lights to maximize the health and volume of the cannabis harvest.
A hydroponic garden may exhibit a growth rate that is between 30% and 50% faster than that of a soil plant. The combination of nutrients, water, and oxygen in the roots are responsible for this faster rate of growth in hydroponic systems.
Please note that these are only guidelines. Feel free to use different flood and drain schedules to meet your specific needs. Many suppliers of hydroponic equipment will give detailed flood and drain recommendations.
In general, flood times don’t need to be much more than 10 minutes. If you are using clay pebbles you may be able to take 1-5 minutes off that flood time. Water retention of your grow medium makes all the difference here. Eventually, you may find that you have the experience to fine tune your flood schedule at various stages of plant growth. Young, smaller plants need less water than fully mature plants. Many growers start with less frequent floods and shorter flood times and gradually increase as the plants mature
How to grow cannabis with hydroponics
Whether you prefer an Afghani Kush, a USA special strain, a CBD rich strain or a skunk you have plenty of good quality cannabis seed options. Remember the cost of your cannabis seeds are a low part of your overall grow costs, so choose your seeds wisely and aim for the best quality weed seeds you can buy. Here are some of the best cannabis seeds for your next hydro grow
All the leading cannabis nutrient companies supply good quality nutrients which will work well in hydroponics. Many growers have their preferred nutrient brand and can be reluctant to change, especially when they have lots of experience with one particular brand.
How and where to germinate your seeds
Perlite is a porous mineral material made from expanded volcanic glass. Because it’s porous, it holds water and oxygen well. Vermiculite is a similar material which is also widely used.
