Pros of Growing Marijuana with CFL Grow Lights and Coco Coir.

These results are not typical for your first try unless you’ve put in a lot of extra research and really watch and tend to your plants throughout your grow. Which brings me to my next point.

When using this method, I’ve found my cannabis to be really resistant to issues or problems, especially considering this method was the one I used for my very first harvest and I had no idea what I was doing when I started.

Yields to Expect: 1-3 ounces/plant (if you follow the directions in this tutorial)

Once you have everything set up as described, simply add your marijuana seeds or clones and set up your lights so that they’re about 4 inches away to start.

In order to prevent over or under-watering, make sure you water thoroughly every time, and wait to water again until the top inch of coco coir feels dry.

What you will need.

The 12-12 light schedule will cause your plants to begin the flowering stage and start focusing on making buds instead of just growing.

So, you can see that it doesn’t cost that much to get started growing cannabis with CFLs! After you get going you can expect to spend about $30/month in electricity, supplies, etc. considering an electricity price of When not using nutrients, make sure you still pH your plain water before your feed your marijuana!.12/kWh (average cost of electricity in the US). So, if you harvest in 3.5 months, which is the average time, you’ll have spent about a total of $300 – $360 for your entire first grow, including setup, electricity, nutrients and maintenance. After that you can expect to pay about $100/grow since you won’t have to invest in most of the setup costs again.

This is what I use for each plant:

A Note about Using CFL Lights.

Flowering Stage.

Note: Perlite can often be found in garden stores or the garden section of places like Home Depot and Lowes. I normally advise against all things Miracle-Gro, but their 8-quart bag of perlite is okay for this tutorial if you can’t find anything else. But remember, never use Miracle-Gro time release soil or their standard nutrient formula! But their perlite is okay.

Don’t be fooled just because it’s easy. Even though I was a complete beginner when I started, I ended up getting 6.2 ounces of dried buds off my very first cannabis plant from my very first grow, which I grew using this system! (Pics below). That is an unusually lot of cannabis for a CFL grow, and took using a LOT of bulbs, but if you read through this whole tutorial you’ll learn step-by-step how you can do it, too.

As the plants get taller and start blooming, you may need to get a couple more CFLs to light them from the sides. Basically if you see any dark or shadowy areas that are more than 6 inches from a CFL, then you should get another CFL to plug in that ‘hole.’

These lights are easily found at the store or online. You can get lower or higher wattage bulbs, but I like bulbs close to the 40w range because they produce a lot of light, but are still a small, manageable size.

You can still get at least a couple of ounces off each plant, even when plants are kept short and you will be able to harvest your crop in only 3-4 months.

Here’s a pic of my very first grow using this method!

What About (5500K) Photography CFLs?

Use the power of reflection to minimize light loss in your marijuana grow space. Cover your walls with something reflective like flat white latex paint (which has 85-95% reflectivity) and/or utilize reflectors to aim more light where you want.

Mix Different Color Bulbs Together Best suited to Any Stage of Life.

Are growing in a very small or short space.

40 or 42W CFLs <— Recommended – great balance of size and brightness (150W equivalent) ◦ Vegetative CFL – 6500k ◦ Flowering CFL – 2700k.

B.) Medium Size CFL Bulb Setup <– Recommended.

A good way to check if a CFL is too close to the plant is to use the “hand test.” Put your hand where the plant is and leave it there for 30 seconds. If it’s too hot for you it’s too hot for your plants and the CFL needs to be moved further away! Plants can grow a lot in a day, so make sure to give yourself some “breathing room” so your plants don’t grow into the bulbs and burn themselves!

As your plant grows, be aware of the height. For any stems that are taller than the rest, gently bend them down and away from the center of the plant until they’re at the same level as the others, securing them down with twisty ties, like this:

Make walls of grow space more reflective to get more light to your plants. A common way to quickly add a lot of reflectivity is to paint walls with flat white latex paint – simply painting your walls with this specific type of paint is really cheap but effective!

When growing cannabis indoors, grow space for a garden is often limited! This is where CFL grow lights shine in every sense of the word! If you have a very small grow space, CFLs may be just what you’re looking for.

CFLs are a great option if you…

An electrical timer is used to make your lights go on and off on a schedule.

You can literally put your plants in a closet under your CFLs and go. Although it’s not the best setup, that’s actually what I did for my first grow (see pic!). I did run into problems with heat and ventilation, plus I can’t believe I started growing on a carpet without even putting down a tarp or blanket! But it was a cheap and simple way to get started!

Today I will walk you through the steps of growing cannabis with CFLs, but you’ll get more from this guide if you at least understand the life cycle of a cannabis plant. Taking 20 minutes to read the basics tutorial will answer 95% of the most common cannabis growing questions new growers have. Plus, having a primer will make the learning experience smoother and more fun!

Twisty ties are a convenient way to tie down stems after bending them, but you can use just about anything to tie down plants except for things like string, which are sharp and can cut into the plant over time.

Vegetative Stage Tactics to Yield More with CFLs.

Step 3: Set Up Your Grow Space.

More Light = Better Results with CFLs. In fact you pretty much can’t really give your plant too much light when growing with CFLs (this isn’t true for all grow lights).

However, you can still use bending and training to make your plant grow however short and bushy you want, no matter how it grows!

Electrical Timer.

It’s a good idea to start training when the plant is young, since new stems are flexible and easy to bend (LST). If you start early, you can train your plant to grow flat and wide under your CFL grow lights with only gentle bending and tying down.

C.) Large Size Bulb CFL Setup.

A.) Small Size CFL Bulb Setup.

Basically you need…

There are bulbs with different CFL color spectrums and it’s generally recommended to get “daylight” (6500k) CFLs for the cannabis vegetative and “soft white” (2700k) CFLs for the flowering stage. Each color spectrum has a small impact on how the plant grows (ex: 6500k encourages slightly more squat growth).

By using the 6500k (sometimes “65k”) colored bulbs during the vegetative stage, you’ll be giving your plants more blue light, which can help a plant grow more short and bushy.

Using CFL bulbs for plants and producing marijuana on your own doesn’t have to be complicated. CFL lights are the most beginner-friendly setup. They are also the best choice for small spaces. Beginners shouldn’t grow too much for their first experience, meaning CFL lighting is a win-win for cannabis growing for beginners.

Since CFL lights are only optimal up to about 12 inches below the light, it’s best to train your plants to grow horizontally instead of vertically. Topping your plants and tying them to grow more laterally is the best way to ensure your plant can grow large without being too tall for CFL full spectrum grow bulbs.

When setting up something like a small CFL closet grow, you might want as little light as possible. Each cannabis plant will require around 80 watts of light, with more being better. Using 2 40 watt CFL bulbs is sufficient for a mini CFL grow.

CFL Light Bulbs For Growing Weed.

However, this doesn’t make or break your cannabis growing operation. If you don’t use a warm white CFL for flowering, you won’t ruin your marijuana. This advice is more about how to set up CFL grow lights in a perfect world.

Many novice cannabis growers do great with CFL setups during the vegetative stage but fail when the plants go to flower. If you want bigger, denser, more potent buds, you need maximal light intensity.

The CFL light spectrum isn’t as important as the total wattage of the light produced when growing cannabis, but it doesn’t hurt to use daylight simulating CFL bulbs during the growing stage and soft-white CFL bulbs during the flowering stage.

The best CFL for vegetative growth will be somewhere around 6500K. A softer spectrum around 2700K will be a good choice for a CFL flowering bulb. These spectrums mimic natural daylight spectrums in Spring/Summer during the growing cycle and Autumn for the flowering cycle.

You can grow marijuana with CFL grow light bulbs in soil or hydroponically. Regardless of the growing medium, light needs remain the same.

CFL is an acronym for compact fluorescent lighting. Compact fluorescent grow light setups are easy to build out because you can buy CFL grow bulbs at almost any store that sells light bulbs! They are just like fluorescent light bars seen in stores and offices but packed into a small lightbulb, allowing the user to reap the benefits of fluorescent light without a large lamp setup.

Pros & Cons Of CFL Lights For Growing Weed.

Cons.

Pros.

Investing in a timer to turn the CFL lights on and off on an optimal schedule for the plant’s stages of life is a good idea. It’s also a good idea to invest in high-quality growing medium and nutrients to improve yields.

Let’s take a look at CFL lights for growing weed. There are quite a few options for lighting when looking to grow cannabis indoors. CFL lightbulbs are becoming more popular because they are beginner-friendly and easy to use. The best CFL lights for growing weed will help you produce more marijuana in small spaces than you thought was possible. If you have a small space that you want to utilize for growing ganja, CFL lights may be the best option!

How Many CFL Lights For One Plant?

Growing cannabis with CFL lights is simple to set up and maintain. Each plant will require around 80 watts of light, although more can be better. Since CFL light bulbs for plant growth don’t produce enough light exposure beyond around 12 inches, the lights will have to be adjustable with height to account for plant growth.

Using CFL bulbs allows you to use daylight mimicking CFL bulbs during the vegetative stage of the plant’s life and use a softer light for the flowering cycle. You don’t want to use a soft white CFL for vegging as it is closer to the sunlight in Autumn when plants start to flower. However, if soft white is all you can find, it will still work as long as you have enough wattage to supply ample light to each plant.

While the wattage of the light produced by the CFL bulbs is more important than the spectrum of light, optimizing the spectrum is a good idea.

The sun produces about 100,000 lumens per square foot, so the closer you can get to this number, the more productive your marijuana plants will be. Building a hood for your CFL lights and concentrating them as close as possible during flowering will help mimic natural sunlight as much as possible.

As mentioned, the coverage of one CFL bulb will only produce enough light exposure to about 12 inches away from the bulb itself. This means that you’ll probably need multiple lights per plant to account for lateral growth.
