Best light bulb for growing weed indoors

There are plants like microgreens that can flourish with a basic lamp. However, marijuana plants require fairly strong and consistent light to help them into the blooming phase. Remember, when you grow cannabis indoors, you’re competing with the sun in terms of light! This means you need high-power lights in your plants’ grow space.

Why Should I Use Indoor Marijuana Grow Lights?

Yes. Cannabis plants grow naturally in the sun, which provides an incredible amount of light. You need to replicate this light source as much as possible, and this is where marijuana grow lights come in. Apart from providing enough light, they also ensure your plants benefit from the right light spectrums.

Are House Lights Good for Plants?

Then again, if you have a grow space of less than five square feet, fluorescent light is enough when your plants are small. You can upgrade to a 250W HPS as the plants get larger. If you have space, an MH light for plants in the vegetative stage and HPS for the blooming phase works well. Using MH lighting throughout is fine but will have fewer flowers, more foliage, and a lower yield.

Fluorescents are a great choice for clones, young plants, supplemental lighting and can save you money on electricity in the vegetative stage compared to using high power lights when plants are too young to use it all anyway. They can also be used to flower plants in spaces that are shorter than what’s possible with other grow lights (aka ‘stealth growing’).

Some types of induction lights are well suited to stadium lighting but honestly they just aren’t that great for growing cannabis and they come with huge price tags. Even a lot of LEDs are cheaper and you’ll get better results with them. You can learn more about induction grow lights here.

Keeping CFLs close results in the best yields and growth

Cannabis plants under a T5 grow light – when plants are trained (like these ones in a Scrog setup) you can get pretty decent yields from fluorescents.
