So if you’re ready to take your grow room to the next level in a few small steps, here are some easy changes you can make to see amazing results in your grow room.

1. Add Supplemental Lighting for Increased Growth and Flowering

You may think your grow light will be enough to get the job done, but even the best grow lights will miss a few spots on your plants. Though reflective material such as mylar and panda film definitely helps and is highly recommended, your main grow light might not offer all the wavelengths of light to benefit your plants. That’s where supplemental lighting comes in handy.

Using a few extra lights in your grow room will ensure that all of your plants are receiving the proper amount of light to help them thrive. Supplemental lights also allow you to curate the right combination of wavelengths so that your plants receive the best possible spectrum.

Supplemental LED Grow Lights

Red light is great for leaf growth and flowering, so you’ll get richer yields. Meanwhile blue light helps with stem growth and promotes height. In addition, LED grow lights feature different diodes that target white light and UV light.

  • 24 Watt Advance Spectrum LED Grow Light Panels (Price: $36.95) — This red LED grow light is great if you’re specifically looking to target leaf and fruit growth during the flowering stage. A blue LED grow light panel like this one is a solid choice if you want to promote stem growth during the vegging stage.
  • KIND XD-Series LED Grow Light Bar (Price: $349.95) — Though it’s a lot wider at 47.4in x 3.1in x 2.3in, this LED grow light is a great choice if you’ve got the space for it and want to maximize your canopy’s exposure to light intensity and a variety of wavelengths of light.
  • California Light Works SolarSystem 550 with UVB Kit LED Grow Light (Price: $1,059.95) — If you want increased growth with UV lighting and customization options, this LED light allows you to adjust and program the spectrum channels and customize light recipes.

These can be linked together to cover any large area you may need some extra lighting for.

2. Use CO2 Bags and Pads to Promote Plant Metabolism, Strength, and Overall Size

As such, incorporating CO2 bags into your grow room is a great way to help your plants grow faster, which means more yields in a shorter amount of time.

  • EZ CO2 Homegrown CO2 XL (Price: $37.00) — CO2 bags like these are sure to give you bigger and better yields. These bags contain fungal mycelial mass that cultivates CO2. Setup is easy: All you need to do is hang the CO2 bags above your plants.

3. Apply Neem Oil to Your Plants to Protect Against Pests

Neem oil can help prevent and get rid of pests like spider mites, white flies, fungus gnats, and nematodes, all while sparing the harmless insects — so you can ensure your plants are safe without having to worry about killing any friendly bugs in the process.

4. Invest in Environmental Controllers and Timers to Maintain a Healthy Grow Room Environment

Although they tend to be on the pricier side, environmental controllers are a great addition to your indoor garden and remove a lot of the busywork associated with maintaining your environment. Different plants need different amounts of light at different intervals depending on where they’re at in the grow cycle. An environmental controller will help you set up the perfect grow schedule. They can also help control the environment so your plants can thrive in ideal conditions.

This all makes for an overall stable environment for your growing area.
