About us. Our 9 year history

GoToGarden started in 2017 out of personal frustration. Our founder was a hobby grower who spent hours navigating online shops that felt built by people who had never touched a plant — cluttered layouts, vague product descriptions, no real guidance on what to actually buy or why. He knew there had to be a better way.

What are the main challenges in water temperature control for indoor growing?

Inconsistent water temperatures can severely impact nutrient uptake and plant health, leading to stunted growth or disease. Maintaining a stable environment is crucial, especially in hydroponic systems where the water reservoir is directly exposed to ambient conditions. Water heaters are designed to combat low temperatures, ensuring solutions remain within the optimal range for root development. For instance, submersible heaters can maintain a consistent 20-34°C, critical for various growth stages.

Explore the range of water temperature control solutions

For growers needing to regulate their water temperature, GoToGarden.com offers both heating and cooling solutions. Our selection includes various BOYU 100W heaters, BOYU 200W heaters, and BOYU 300W heaters, suitable for tanks up to 350 liters, alongside 300W glass heaters. For cooling, we provide powerful Water Chiller HS52A with 2200 l/h flow, Water Chiller HS66A with 2500 l/h flow, and the high-capacity Water Chiller HS90A at 3000 l/h. These complement our broader offerings in Komponenty, Hadice, Netafim závlaha, Nádrže, Příslušenství pro závlahu, Reverzní osmóza & vodní filtry, Rozvody kapilár, Solární závlaha, Spojky, and Vzduchování.

Differentiating between heating and cooling technologies

BOYU aquarium heaters, available in 100W, 200W, and 300W models, are designed for simplicity and reliability, featuring built-in thermostats and operation indicators for tanks up to 350L. The 300W glass heater offers manual control within a 20-34°C range, ideal for growers who prefer direct adjustment. Water chillers like the HS52A, HS66A, and HS90A, featuring digital controls and titanium evaporators, are engineered for precise temperature management in larger systems, catering to more demanding cultivation projects.

Selecting the right water temperature control

Growers using hydroponic systems during the vegetative stage often need to maintain temperatures around 20-24°C. For these setups, a BOYU 100W heater or a Water Chiller HS52A might be suitable depending on ambient conditions. During the flowering stage, maintaining cooler temperatures can be beneficial, making chillers like the Water Chiller HS66A a preferred choice. For smaller tanks or simpler setups, manual control heaters like the 300W glass heater provide flexibility, while the Water Chiller HS90A is best for professional cultivators with large reservoirs requiring rapid cooling.

Frequently Asked Questions

How do I choose between a water heater and a water chiller?

If your ambient room temperature is consistently below the desired water temperature for your plants, a water heater is suitable. If the ambient temperature is higher, causing your reservoir to overheat, a water chiller is necessary.

What wattage heater do I need for my reservoir?

For reservoirs up to 120L, a 100W heater is generally sufficient. For tanks between 200-250L, a 200W heater is recommended, and for larger tanks up to 350L, a 300W heater is appropriate.

What is the optimal temperature range for hydroponic water?

The optimal temperature range for most hydroponic systems is between 20°C and 24°C. Temperatures outside this range can affect oxygen levels and nutrient absorption. The glass heater allows manual control between 20-34°C.
