Gertens is still a family-owned business with a focus on giving customers the ability to buy high-quality plants and trees directly from a local grower.  After all, IT'S ONLY NATURAL TO BUY FROM THE GROWER.

Details

Moisture readings register on a scale of 0 (dry) to 10 (moist); light readings range from 0 LUX (low light) to 2000 LUX (very strong light); accurate pH readings range between pH 3.5 and 8. The durable, easy-to-read tester is suitable for indoors or out and needs no batteries to operate. Remove from soil and clean prongs after each use to ensure the moisture meter stays in top performance shape.

Grow lights should be kept roughly 4-5” above the top of seedling leaves. If you are using very powerful LEDs, you could even keep them 8-10” away.
Grow lights should be used to mimic a natural sunlight cycle for plants. We recommend using them 12 hours a day, from roughly 7am to 7pm.  
A variety of seedling trays exist for seed starting. If you are starting smaller seeds, a simple peat cell tray works great. However, the larger the seed, the larger the initial pot should be. If you are starting larger seeds indoors such as: sunflowers...
