There are a number of different components that you need to buy that will then be assembled together in the form of one final setup. This includes grow tents, grow lights, fans, ducting, filters, timers, soil, nutrients and a lot of other items. Instead of buying them all separately from different sellers, many growers prefer buying ‘weed grow kits’ which ensure that they are getting all the products at one place and from one seller which they can quickly buy and set up with ease at once. 

Over the course of this article, we shall be reviewing some of the best weed grow kits in 2020 and reviewing them for you so that you know exactly what you are getting when you buy them. This is particularly useful for someone who is starting out because this gives you everything at one place.

We will also answer some basic questions on these grow kits as well as provide you with a buyer’s guide for the same. We hope that this article helps you start off with your growing journey in an easier way. 

What All Do You Need to Grow Weed?

Before we delve into the best weed grow kits in 2020 for growing marijuana plants indoors, here’s a list of ALL the things that are needed in the process of growing marijuana:

1. Grow Tent

A grow tent helps you create a space inside which you can control the various environmental factors for your plants. It provides a private and safe space for the plants to grow where they will be free of any other external interferences. A grow tent also provides the plants with protection by making sure insects and pests do not enter the grow area. The insides of the tent’s canvas are lined with reflective mylar layers which help bounce the light back on to the plants thereby improving the efficiency and effectiveness of the grow light.


2. Grow Lights

A grow light is the next and perhaps the most important thing that indoor growers need to grow marijuana. In the absence of sunlight, there needs to be an artificial source of light and with the help of a good full-spectrum grow light, one can create an effect which can simulate the natural sunlight, providing the right spectrum of the right wavelength to the plants during different phases of their growth. Grow lights are helpful as they help the plants with various processes, the most important of it being photosynthesis via which plants create their ‘food’ and grow better.

3. Soil

The soil in which you grow your plants is quite important and most grow kits will provide you a package of soil as well. Your soil needs to be rich in three basic nutrients Nitrogen, Phosphorus and Potassium. In addition to that there also need to be a number of organic elements such as earthworm castings, bat guano and various other similar elements which need to be present in the soil for it to help the plant grow properly. 

3. Nutrients

No soil is perfect and plants need a little ‘boost’ during different phases of their growth. You need to ensure you’re giving your plant the right kind of nutrients at the right time mixed with water in the soil. Most of these weed grow kits come with a basic supply of nutrients which will help you give a much-needed boost to your plants.

4. Inline Fans and Ducting Pipes

Air circulation is another thing that needs to be artificially created inside a grow tent. Inline fans help with just that. They help create a breeze inside the grow tent and the ducting provides a way for cooler air to enter and hotter air to exit the tent. All our grow kit combos come with inline fans as well as ducting pipes which will ensure that the grow tent remains cool as well as breezy. Breeze is also good for strengthening the stem. 

5. Carbon Filter

The marijuana plant tends to emit a very strong smell coming off of it due to the terpenes. A carbon filter helps catch all that smell inside the grow tent and makes sure you growing marijuana remains a smell-proof operation and no one suspects you. Almost all grow kits come with a carbon filter – it is a part of the ventilation system that goes along with the fans and the ducting.

6. Timer

Having a timer is always beneficial as that will allow you to automatically turn off and turn on lighting without actually having to be physically present to do so. Timers are perfect for those who want to create a day-night balance for their plant without constantly worrying about manually switching them on and off.

7. Thermometers

An ideal temperature has to be maintained during the different phases of growth. About 20-25 degrees C during the vegetative phase and about 25-28 degrees C during the flowering phase. Hence, you need a thermometer to make sure it is not higher or lower than the required limits. 

7. Humidifier/Dehumidifiers

Humidity is very important for growing marijuana. Young plants (seedlings) need a humid environment while growing up as that’s where they get their water from because their roots aren’t fully developed. This can be lowered a little during the vegetative phase and even further during the flowering phase as you need more water and nutrients going via roots in the final phase. Humidifiers and dehumidifiers are important but not necessary – these aren’t usually bundled along in a weed grow kit but you can buy them separately, particularly if you’re living in an area where there’s too much or too little humidity.

8. Air Conditioners/Air Heaters

Similar to humidifiers and dehumidifiers, Air conditioners and heaters aren’t a compulsion but something that adds on to your growing experience. Plants need an ideal temperature to grow and if you live in an area which is too hot or too cold, you will need these devices to ensure that the temperatures that your plants are getting are perfect for their growth. These, too, won’t be a part of weed grow kits and have to be bought separately. 

One final word on these equipment that you need to grow weed: it is not likely that any grow kit in the world would provide you with ALL of these elements. While you will need to buy some of them on your own, try and get a weed grow kit which checks most of the boxes off of this list.

Buyer’s Guide: What to Look For Before Buying a Weed Grow Kit?

Some basic things that you must take care of before you buy a weed grow kit are- 

1. The size of your setup vs the size of the tent

You must make sure that your grow tent is big enough to cover the way your pots have been set up. If the tent is smaller than the area that your pots occupy, then we suggest you look for a grow kit which offers a bigger-sized grow tent.

2. What all are you getting

One of the most basic and the first things that you must check in any grow kit is – what all are you getting when you buy it. The more the number of products the better it is for you. Make sure all the necessary bits are in place as it’d be quite disappointing if you buy the kit and find out that some key elements are missing.

3. The details of the lighting 

Grow lights are undisputedly the most important element when it comes to growing marijuana indoors. You must ensure that your grow kit has a very good quality grow light. Possibly a full-spectrum LED grow light which has a decent wattage. The lighting must not heat up and must be safe to use as well. Dimmable lights are even better but they’re rare to find in a grow kit.

4. The circulation system

Make sure that your grow tent has enough openings for the air to flow in and out of it – and the ducting, fans and filters are of good quality. This will help you make sure that the temperature inside the tent remains cool and that there’s a steady flow of air. Having a breezy environment is good for your stem’s sturdiness as well as helps keeps insects and pests away.

5. Soil and Nutrients

If you’re getting soil and nutrients as a part of your grow kit, check if they’re the right kind of products that you’d want for your weed to grow in. If there’s something lacking in this front, we suggest you order it separately. Sometimes growers complain that the soil is not adequate for their setup or the nutrient bottles are too small so that’s one more thing you’d need to check right at the onset.

6. Cost and Warranty

Last but not the least, you must also check the cost and the warranty of the products that you are getting. Some growers prefer checking out all of these products individually and seeing if buying them ala carte is a better deal (usually grow kits are cheaper). You must also check for the warranty on each individual product.
