The final step involves harvesting your plants. Once you get used to the process, you’ll find it more enjoyable than tedious.
A hydroponic system delivers all necessary mineral salt nutrients to plants in water. If you want to choose hydroponic over traditional soil, there are several types which are straightforward and fairly easy to understand. These include Ebb and Flow, Flood and drain and DWC or Deep Water Culture.
For example, most growers use one of two main types of HID lamps/bulbs depending on the developmental stage. Metal halide (MH) bulbs are best during vegetative growth. High-Pressure Sodium (HPS) is the preferred option for the mature flowering stage. If you can only afford one, choose HPS as they are much better for flowering and are more efficient on a ‘watt-to-light’ scale.
It shouldn’t take long to get the hang of things and start producing some beautiful, flowering cannabis plants, but you’ll need to make room as your plants grow. From the first signs of flowering, you can expect a plant to double or even triple in size by harvest time.
Step 10: Cut Your Cannabis Plants Down — Carefully!
Ensuring your plants get the right nutrients is probably second only to lighting in terms of importance. Proper nutrient selection and application are among the most critical factors in growing premium-grade cannabis. While weed is resilient, growing it in sub-optimal conditions means you will miss out on yield and potency.
Make sure there are holes drilled into your growing container so the water can drain out. When watering, try, and only moisten the soil rather than saturating it. This allows you to fully saturate the pot without overwatering. Try not to water until they’re almost dry. This is called cycling.
While this is true to an extent, there is such a thing as “too much water.” Overwatering your indoor cannabis plants can prove detrimental to their productivity, and potentially stunt or kill them!

By “small,” I mean nothing more than a few plants at most. You can start with just one or two plants. There’s an inevitable learning curve involved with growing weed indoors and you’re bound to make some mistakes.
There are some outstanding pre-filled soil kits specially designed for increased airflow. Keep these in mind when deciding what to grow your first cannabis plants in.
Before you purchase any equipment, it is important to understand the possible limitations of an indoor garden. Consider the height of the ceiling, how much insulation your space offers, and your ease of access to electricity and water. Some local jurisdictions may also ask that indoor gardens mitigate odors during the flowering phase.
Ebb and flow systems, also known as flood and drain systems, are a popular type of recirculating system that uses a pump to bring water and nutrients from a reservoir into a flood tray where the plants are positioned in their grow medium. The nutrient solution floods the tray and gets absorbed by the roots and medium before slowly draining back into the reservoir. This process repeats itself on a timer to ensure that plants are properly hydrated.
Rockwool , also known as mineral wool, is one of the most common forms of hydroponic media for the beginning stage of a plant’s life. Rockwool is an inert substance, and its composition of mineral or rock fibers provides a relatively sterile environment with a unique capacity to hold water. Rockwool will quickly expose any watering or feeding mistakes. Missing even one day of watering could be detrimental when using rockwool, especially for tender young plants.
Unlike outdoor cultivation — where you almost always use soil to grow your plants — growing indoors offers several different options for growing systems and media. Some media are easier to work with than others, while some are a little trickier, but offer more control over the finer details. Different media retain moisture at different rates, which in turn determines how often plants need to be watered. Some media harbor beneficial microbes that can help roots absorb nutrients better.
Setting up your grow: choosing a space
CO2 can be supplemented into an indoor garden using compressed gas tanks or generators. Using compressed CO2 tanks is the most common method because they’re readily available, easy to set up, and do not add any extra heat to your room the way a CO2 generator does.
