These plants are both 8 weeks old from 12/12 and have been grown in the same setup their entire lives. You can see the plants were the same size so you might think the yields were similar between the plants. Looks can be deceiving, because the strain has a huge impact on your yields after harvest.

If you want to be able to impress your friends and fellow growers by hitting 1 gram/watt, I’ll teach you how.

Growers often measure yields differently from each other. This can make comparing yields kind of like comparing apples to oranges.

Adding equipment to control the temperature and humidity (like fans, ducting, an AC, a humidifier, dehumidifier, etc) gives growers an edge, but they may also increase your setup and electricity costs.

A lot of people believe that you need a 1000 watt artificial light to grow hemp indoors. The reality is, you can successfully grow medicinal herbs with far less wattage, saving you money on your electricity bill while growing healthier plants. So, how much wattage do you really need to grow indoors?

Do you need 1000W to grow indoors? Not with LED Habitats Grow Lights

Let’s take a look at this short day plants-growing myth, and how you can grow indoors with eco-friendly (and wallet-friendly) LED grow lights.

Where the myth that you need 1000W to grow hemp comes from

The idea that we need 1000 watts to grow hemp comes from the days when it was common to use High Pressure Sodium (HPS) lights to grow anything indoors. At the time, HPS lights were the only decent artificial light source on the market, and a 1000 watt light was necessary for a sufficient photosynthetic light spectrum.

The easiest way to think of them is to consider the 315w bulb equivalent to 600w of MH or HPS light and the 630 watt dual bulb fixtures equivalent to 1000 watts.

One thing to note: this is based on the maximum coverage areas for each bulb strength.

By Wattage

It should be. Just try and add more lights, if needed.

By Coverage Area

For example, say you have a space that is 10 by 20 feet, or 200 square feet. That is perfectly divisible by 4 (the 150 watt bulb) or 25 (the 1000 watt bulb).
