Growing Hydroponic Spinach in Your iHarvest®

Eating the right ‘fuel’ is essential for good health. Spinach is a superfood loaded with many kinds of nutrients such as iron, protein, minerals, and vitamins important for hair, bone, and skin health. The plant can also improve blood glucose control as well as lower the risk of cancer. In order to take full advantage of these benefits, you must be able to eat the vegetable on a regular basis. 

Germinating Your Spinach:

Growing your own spinach indoor in your iHarvest®  indoor garden system ensures that you have easy access to fresh spinach any time of the year. Because it can be a bit difficult to grow the vegetable from seed, however, there are a few tools to keep in mind as you begin your indoor spinach garden. Place three to five seeds in each rapid rooter then place the seedlings in the refrigerator for about eight days. Spinach is a cool-weather plant, so the time in the refrigerator is a good way to get them get started. 

You can also look at the ‘paper towel’ method if you’d prefer a more rugged DIY solution. The same tip about placing seedlings into the refrigerator applies to this method of germination.

Best Lighting For Growing Spinach Indoor:

Spinach doesn’t require quite as much light as other plants when grown hydroponically. They can thrive with anywhere from 10-14 hours of light, although the higher end of that range is best. Light quality is important, so make sure you invest in a reliable LED option

PPM Range:

The iHarvest® includes a PPM (parts per million) tester. This measures the nutrients present in a water solution and is an overlooked tool that can grant important insight into its nutritional value. When growing spinach in your iHarvest®, keep the PPM range between 1260 and 1610. For best results, pair it with plants that require a similar range such as chives, pumpkin, and squash

The Right pH Range To Grow Spinach:

The iHarvest® also offers a pH tester to make growing your own spinach easy. The right pH is essential for proper plant growth and ensures that plants can absorb the nutrients they need to thrive. Keep your pH between 5.5 and 6.2 for best results.

Nutrients For Spinach Growing:

You want your spinach to have plenty of nutrients so that the seedlings have the chance to develop into healthy mature plants. One way to take some of the guesswork out of this part of indoor garden growing is to use a solution such as MaxiGro that is designed to offer leafy green plants everything they need to thrive.

Pruning Your Spinach:

Indoor spinach is fairly low maintenance and requires little in the way of pruning. All you need to do is harvest the individual leaves as they mature to promote new growth.

Harvesting Your Spinach

Most varieties of spinach mature within 37 to 45 days, although you need to keep an eye out for leaves that mature more quickly. You can harvest the plant leaf-by-leaf beginning with the outer leaves and working your way to the center, or you can cut it at its base with scissors. Because spinach doesn’t keep very long after being harvested, allow your spinach needs to guide how you harvest leaves. 

Growing an indoor spinach garden doesn’t have to be a difficult endeavor. The iHarvest® gives you the best chance to create thriving and healthy plants year-round and is a great investment for both amateur and experienced gardeners.
