Low energy CFL bulbs are ideal for growing cannabis plants in small spaces. CFL lamps are often used in grow tents smaller than one square metre in size, such as a 60 or 80 square metre grow tent.

In this section you will find available bulbs for growth, for the flowering phase or both, which are mixed energy saving bulbs, emitting both colours of light, white light and red light, to develop the plant in both phases.

Low energy CFL bulbs for cannabis growing: The guiding light for your plants

What are low energy CFL bulbs for indoor growing and what are they used for?

Low energy CFL bulbs, also known as CFL (Compact Fluorescent Lamp), are artificial light sources used in indoor cannabis growing. These bulbs are specially designed to provide the spectrum of light needed for the growth and development of cannabis plants during the vegetative phase.

Why don’t we need to plug them into a transformer?

Energy saving CFL bulbs do not require a dedicated transformer to operate due to their energy efficient design. Unlike other high wattage bulbs, low energy bulbs have a transformer built into the base of the bulb, which is why they need to be connected directly to our aluminium reflector for operation.

Different light spectrums and the importance of the light spectrum

Low energy CFL lamps emit different light spectra, which refer to the colours and wavelengths of the light they produce. In relation to the colour of light emitted by the bulb we will use it during the growing phase, flowering or the whole crop.

The light spectrum is crucial in cannabis cultivation, as it influences the growth and development of plants at every stage. The right spectrum ensures vigorous and healthy growth, which translates into higher yields of buds.

Differences between grow bulbs, flowering bulbs and mixed bulbs

Grow bulbs: These are bulbs designed specifically for the vegetative phase of the plants. They emit a blue spectrum of light that promotes vigorous growth of leaves and stems.

Flowering bulbs: These bulbs are intended for the flowering phase of cannabis plants. They emit a red/orange light spectrum that stimulates the yield of dense, resinous flowers.

Mixed bulbs: These are versatile bulbs that offer a full spectrum of light, suitable for both vegetative growth and the flowering phase. They are a practical option for growers with limited space or who want to simplify the use of different bulbs.

Advantages of growing with low energy CFL bulbs

More sustainable bulbs

Energy efficiency: low energy CFL bulbs are highly efficient in terms of energy consumption. Compared to traditional bulbs, such as incandescent bulbs, CFLs consume significantly less energy, resulting in lower electricity bills.

Low heat: low energy CFL bulbs generate much less heat compared to incandescent and halogen bulbs. This is beneficial for indoor growing, as it helps to maintain a proper temperature in the grow space, preventing plants from excessive heat damage.

Long life: low energy CFL lamps have a longer lifespan than incandescent and halogen bulbs. They can last up to 10 times longer, which means fewer replacements and less waste.

Environmentally friendly: Due to their energy efficiency and long lifespan, low energy CFL bulbs generate less waste and contribute to reduced carbon emissions, making them a more environmentally friendly option.

Affordable cost: Energy saving CFL bulbs are relatively inexpensive compared to other lighting options for indoor growing. Their affordable price makes them a popular choice for beginner growers and those on a budget.

Low energy CFL bulbs that suit the best crop.

Suitable light spectrum: Low energy CFL lamps are designed to provide a suitable light spectrum for the vegetative and flowering phase of cannabis plants. They emit light in the spectrum part of the spectrum, which promotes healthy growth and vigorous development of leaves and stems.

Versatility: Low energy bulbs are available in different wattages and sizes, allowing them to be adapted to various growing spaces. There are also mixed options that cover both the vegetative growth and flowering phase, which simplifies the cultivation process. .

In conclusion, low energy CFL lamps are an excellent choice for indoor cannabis cultivation due to their energy efficiency, low heat output, long life span, adequate light spectrum and affordability. These bulbs provide the necessary illumination for healthy plant growth during the vegetative phase, leading to a successful crop and a bountiful harvest.

However, if you are looking for energy efficient lamps for larger areas, we recommend that you check out LED lights, as you will find options that may be better suited to your grow.
