Grow Tent Kit Mars Hydro SP3000 2’x4’ Review

Partnered with: Mars Hydro

Starting to grow your own cannabis at home can be both exciting and overwhelming. Loads of information to learn and many items to buy. When you purchase every item separately instead of a grow tent kit, you need to calculate the best grow light for a determined grow tent, as well as the volume of air you need to circulate and control many other things like temperature and humidity levels.

Advanced growers usually know how to calculate this, but the same can be exhausting for someone who’s just starting.

Let’s see what are these items and how they solve the needs of cannabis growers:

Grow Tent

A grow tent is a portable, enclosed structure that provides a controlled environment for growing plants indoors. It is designed to be used in a small space, such as a basement, garage, or spare room.

The grow tent helps to create the ideal conditions for plant growth by providing a controlled environment with the right amount of light, temperature, humidity, and airflow.

Light contamination can delay cannabis flowering and cause many problems. The Mars Hydro 2’x4′ grow tent is made of 1680D canvas to avoid light leakage. It comes with a reflective interior to increase light intensity around the plants, which translates into rapid growth.

The Mars tent is built with an iron frame, which makes it sturdy and reliable, allowing cannabis growers to control the growing environment easily and keep things private.

The removable floor tray makes it easier to clean, which is very important to keep plants healthy and pest-free.

LED Grow light

LED grow lights are a type of lighting system specifically designed for use in grow tents and other indoor growing environments. LED grow light fixtures provide plants with the wavelengths of light that they need for photosynthesis, and can be adjusted to meet the needs of plants at different stages of growth.

This kit comes with the Mars Hydro SP3000 LED grow light, which is an excellent option for beginner and advanced growers. SP3000 is a large single-strip LED grow light fitted with high-quality Samsung LM301B chips and a broad spectrum of boosted red light.
(Red Light: 650-660nm; Warm white: 2800k-3200k; Cold White: 4800k-5000k)

Light intensity and spectra

Photosynthetically active radiation (PAR) is the spectral range of light from 400 to 700 nanometers that plants are able to use in the process of photosynthesis. The best spectral range for growing cannabis plants is similar to sunlight and includes warm and cold white light and red light as well (660nm).

The SP 3000 light panel delivers significant PAR (Photosynthetic Active Radiation) specifically designed for plant growth. This light has broad spectra with an enhanced red that contributes to flowering.

Photosynthetic Photon Flux Density (PPFD) measures the number of photons (how much light) from a light source at a given time that reaches a specific area. For the flowering stage, we recommend a maximum PPFD of 1000 μmol/m2.s (without using CO2).

The Samsung LM301B diodes and 660nm dark red Osram diodes give this fixture an excellent PPFD and broad spectrum for growing from seedling through the flowering stage.

The SP 3000 has an output (PPF photosynthetic photon flux) of 824 umol/S, which is great for growing cannabis plants at all stages in a grow tent at home. A high-intensity light that can boost your yields through year-round production.

You can adjust the light intensity with the dimmer function by changing the distance between the light and the canopy of your growth. Each stage of the cannabis plant has a different PPFD recommended, here’s a table guide for beginners.

STAGEPPFD recommended
Seedling100 – 300 μmol/m2.s
Vegetative400 – 600 μmol/m2.s
Flowering800 – 1,000 μmol/m2.s

Heat dissipation

The SP 3000 comes with new technology for heat dissipation, with stable die-casting aluminum and transpiration gaps. These 3D cool fins allow fast heat conduction leading to faster heat dissipation. This design reduces the risk of overheating and improves the overall efficiency of the grow light.

Efficacy: the SP 3000 fixture consumes 300 watts and offers 2.8umol/j efficacy. It means the electricity bill will be significantly lower in comparison to HPS and other less efficient LED grow light technologies. This grow light saves 25% of power and increases light intensity by 30% over the HPS.

Ventilation and Air Filtering for a grow tent

Inline Fan

An inline fan is a type of exhaust fan used to ventilate the grow tent by removing excess heat and moisture. The fan is usually mounted on the outside of the grow tent and is connected to the inside of the tent by a duct. The inline fan helps to maintain the proper temperature and humidity levels inside the grow tent, which is important for the health and growth of the plants.

This ventilation and filtration system transfers fresh air in and out to preserve a well-balanced environment setting. The 4” inline fan provides a powerful 350CFM airflow. It’s potent and silent at the same time.

Carbon filter

A carbon filter is a device that is used to remove unwanted odors from the air inside the grow tent. It works by passing the air through a bed of activated carbon, which absorbs odors and other impurities.

The carbon filter helps to keep the air inside the grow tent fresh and clean, which is important for the health and well-being of the plants and the grower. The 6” carbon filter helps eliminate strong odors from the grow room while the inline fan is operating.

Duct tubing

Duct tubing consists of a flexible, insulated tube that is used to connect the inline fan to the grow tent and other ventilation components. It helps to ensure that the air is properly circulated throughout the grow tent, and can be adjusted to meet the specific needs of the plants.

Useful Gadgets For Indoor Growing


A timer is a device that is used to control when the grow lights and other electrical equipment in the grow tent are turned on and off. This is important because plants have different light and temperature requirements at different stages of growth, and the timer can be set to provide the plants with the right amount of light and heat at the right times.

Thermo-Hygrometer (temperature and humidity monitor)

A thermo-hygrometer is a digital device that is used to measure the temperature and humidity level in the grow tent. This is important because the proper humidity level and temperature are essential for the health and growth of cannabis plants. By monitoring the temperature and humidity levels in the grow tent, you can ensure that the plants are getting the right environment to grow healthy and strong and avoid pests at the same time.

Grow bags

Grow bags are containers made of fabric used to grow plants in a controlled environment. They are made of a durable, breathable fabric, and can be used to grow a variety of plants, including herbs, vegetables, and flowers.

Plant nets

Plant nets are a type of trellis or support system used to help plants grow upright. They are often used in grow tents to help support heavy plants or to train plants to grow in a particular direction. Plant nets help growers organize their grow tents and train their plants to optimize space.

Grow bags and grow nets make it easier to organize your plants.
