best system to grow cannabis indoors

Cannabis, like all plants, prefers certain environmental conditions in order to thrive. Temperature, humidity, light intensity, and airflow are all factors that will need to be monitored and regulated in order to keep cannabis healthy through its different phases.

Privacy and security

One trick to avoid hot temps is to have the grow lights on during the evening, when it’s cooler outside, and leave the lights off during the day when it’s hot. This may help bring down the temps, but you’ll only be able to work on the plants at nighttime when the lights are on.

Indoor space

The flowering stage will always take about eight weeks—some strains take seven, some nine, some even more, it depends on the strain.

Both NFT and aeroponic systems can achieve large yields and high-quality flowers, but they can also be difficult to manage, as they offer little to no buffering for delicate root systems. Getting the NFT solution to the proper flow lev- els in the conduit, or ensuring that all spray emitters (and the spaghetti lines feeding them) have the proper pressure in aeroponic systems, can be challenging for first-time growers.

Deep-water culture setups are great for beginners and more advanced growers as well. DWC — also known as “bucket systems” or “hydro pots” — utilizes large buckets or containers, with netted pots sitting in a hole in the top so that the roots hang down into the container. These buckets are linked to a single reservoir, with the size of the reservoir ultimately determining how many plant containers can be linked together.

When heated, HEC can produce a tough and stable substrate that is porous and capable of absorbing decent amounts of water. However, like rockwool, HEC offers no nutritional value. Both HEC and rockwool can be difficult to master because they require the grower to intimately understand nutrients and ppm levels within the solutions for feeding. That being said, HEC is a great medium for use in heavy-watering hydroponic systems. The clay substrate is weighty enough to keep peat or rockwool plugs with rooted seedlings or clones in place during heavy water flows, and it also allows for easy drainage and extra aeration. Remember, roots breathe in oxygen, so airflow in the root zone is integral to healthy plant development.

Top-Feed Spray Emitter

The only pitfall with this system is that it’s not ideal for some nutrient programs, especially synthetic nutrients that are heavy in salts. This is simply because salts build up quickly in thin irrigation lines and often clog spray emitters, which rely on tiny holes in the nozzle heads to create pressure and an even distribution of nutrient solution.

When choosing a soilless medium, it’s important to read the ingredients label carefully and have a good idea about what you desire beforehand. Most soil- less grow mediums are mixtures of the following components:

To break it down even further, active grow systems can be divided into two categories: hydroponic and non-hydroponic systems.

Before you head out to your local hydro shop, there are a few things to consider beyond just what type of grow system will fit in your available space. How does the system work exactly, and how much time and attention will it need? Are there moving parts that can break? Is there a lot of water involved that can flood a room or attract pests? And perhaps most importantly, what kind of medium will it require?
