Best Grow Light for Seedlings Reviews

Regardless of whether you begin your cannabis garden using clones or seedlings, you need to choose the right lighting system during the early stage of growth. Although various technologies can be effective at different stages of growth, some are better than others. When looking at the best lighting for an indoor garden, it is more than just the power consumption but rather how efficient the light is in promoting a seamless transition between the different stages of growth.

The lighting is the driving force behind an indoor garden. It is common for cannabis growers to designate three different grow rooms for the three different stages of growth, each with its lighting. It is very crucial that you pay close attention to the seedling stage as to how the light affects the young plants will determine the yields during harvest. Here are some of the lighting systems that you can employ during your marijuana seedling growing phase.

Different Lights and How They Fair in the Seedling Stage

High-Intensity Discharge (HID)

They comprise of high-pressure sodium lights and metal halides. They are the standard lighting options that many indoor growers prefer to use. Although there are newer technologies that are working on increasing their PAR efficiency, HID lighting still dominates with its intensity. It is the high intensity that makes it unsuitable for use during the cannabis seedling stage. You should not provide your plants with a high-intensity light during their first week of growth. Young cannabis plants are tender. When you expose your plants to intense light, the light can hinder healthy development.

However, you can use HIDs on seedlings if they share the same grow area with plants in their vegetative state. Some cannabis growers combine the two since they have the same photoperiods. It is not ideal but practical. To ensure that they correlate and grow well together, you should place the seedlings on the outer edge of the footprint while the vegetative plants stay directly under the source.

LED

Light emitting diodes are continuing to improve in popularity among the indoor cannabis growers. They contain a customized lighting spectrum that is beneficial to plants. When you consider the PAR levels, LEDs should come first. They can work in all the stages of plant growth. However, you should know that not all LEDs are the same. They are different due to either their wattage, spectrum, or sizes. During the seedling stage, you want to use an LED with low wattage. You should also consider the light spectrum. Red and blue light frequencies help the young plants grow efficiently and effectively. When looking for an LED light to use, check to find one that is specially made to work for the seedling stage.

Fluorescent

Many professional cannabis growers rely on the fluorescent bulb during the seedling growth phase, specifically, the T5 fluorescent. They are incredibly efficient and distribute light better than any other technology. All the lamps in a T5 fluorescent system ensure that all the plants receive an equal amount of light. Induction fluorescent bulb is another option that is gaining popularity among many indoor growers since they have a closed tube design.

Although many growers may hesitate to acquire a fluorescent system due to the high initial costs, they are an excellent option for the seedling phase.

Summing Up

One crucial consideration to make when choosing a lighting system for the seedling phase is the amount of light that the plants will require. When planting in a grow tent, you need to provide your seedlings with a light intensity of about 20 to 30 watts per square feet. You should remember that a high light intensity at this stage can hinder growth in your plants. The seedling stage is the foundation of the entire cannabis plant life. When the plants become stressed or unhealthy during this stage, it will affect all the other growth stages. If you want your cannabis plants to have excellent growth potential, you need to provide them with a good start.
