Environment FAQ

What is the best temperature and humidity for my indoor grow room?

Most plants will grow well indoors if you keep your grow area between 70-80 degrees F and 40-60% relative humidity with your lights on. It is recommended to keep your temperature within 10 degrees of your average day temp when the lights are off.

Grow Lighting FAQ

FAQ about indoor grow lighting.

How long should I keep my lights on?

For vegetative plants, keep your lights on an 18 hours on/6 hours off cycle. For flowering plants, switch your light timer to a 12 hours on/12 hours off cycle to stimulate flower production after they’ve grown to the desired size in vegetative growth cycle.

How much light do I need for my indoor garden?

Most flowering plants grow best under 20-30 watts of artificial lighting per square foot of plant canopy. It is important to be careful not to go overboard, as too much light can cause burning or bleaching of the leaves and flowers.

Example: 5’x5′ plant canopy = 25 sq. ft.
25 sq ft growing area * 20-30W = 500-750W

Recommended to use between 500-750W for a 5’x5′ plant canopy.

Hydroponics FAQ

Frequently Asked Questions about hydroponic systems and techniques.

Does hydroponics work outdoors?

Yes, plants can grow hydroponically outdoors. With a bit of extra precaution to keep you system protected from the elements and outdoor pests, hydroponic systems can work great outside.

What are common types of hydroponic systems?

The most popular hydroponic system types are deep water culture, ebb & flow, aeroponic and passive. The difference between hydroponic systems is in how the plant and root system are supported and how the nutrient solution is delivered. In “active” hydroponic systems such as ebb & flow or aeroponics, a submersible pump will typically supply water and nutrients to the root zone, while passive systems rely on gravity or wicking.

What are the most common grow medias to use in hydroponics?

The most popular medias to use in hydroponics are clay pebbles, rockwool, and coco fiber. Each type has its own unique benefits. We stock a variety of each type of grow media.

What is Hydroponics?

Hydroponics is the practice of growing plants using an oxygenated solution of water and nutrients, without any traditional soil. Almost any plant can be grown in a hydroponic style and plants grown this way can even grow faster and larger than their counterparts grown in soil!


How often should I check and adjust my pH?

You should check your pH and ppm levels in your nutrient solution on a daily basis when starting any new hydroponic garden or fertilizer program and make adjustments if necessary by adding pH Up/Down solution, but may reduce frequency once comfortable. The pH can change over time depending on many factors including nutrient content, aeration, and temperature so it is important for gardeners to check regularly.

What is pH?

pH stands for potential hydrogen and is a measure of a solutions alkalinity represented on a scale from 0-14. A pH measure of 7 is considered neutral. A solution is considered basic if it measures between 7 and 14, while a solution measuring 0 to 7 is considered acidic. The pH of a nutrient solution is very important in hydroponics because it plays a big role in which macro and micro nutrients a plant can uptake.

What is the correct pH for my grow medium?

Generally speaking, a rootzone pH of 6.0 to 6.5 in soil will be favorable for most plants. In coco or hydroponic applications, use a slightly lower pH of 5.7-6.0.
