Specially formulated hydroponic fertilizer mixtures are required and should be tested after dilution to ensure a pH level of between five and six. This nutrient solution should be changed every two weeks and in between changes should be checked so the volume is kept level by adding more water only and not additional formula. Plants with plenty of oxygen in the root system will also absorb nutrients faster. The nutrients in a hydroponic system are mixed with water and sent directly to the root system. Hydroponic systems use apparatus that are varied. There are two basic divisions between systems: water culture and media based. The speed of growth combined with the control over the growing environment means higher quality crops. The worry over soil born diseases and pests are greatly reduced, plus weeding is a thing of the past. For commercial growers, rapid harvest and higher yields are great reasons to grow hydroponically. Incorporating hydroponics into an outdoor garden can help add interest and intrigue. The natural conditions available outdoors in the summer make it a perfect time to experiment with the various types of hydroponic cultivation. Annual flowers, fruit, herbs, and vegetables do exceptionally well with hydroponics. The cards are useful for monitoring spider mites and many other small bugs. The bright yellow color will attract the spider mites where they will adhere to the sticky surface. The yellow cards are best for preventing the infestations of spider mites, but can’t act alone in eliminating them. It’s best to identify spider mites before their infestation grows too large, eliminating the spider mites with early detection will save your hydroponically grown produce. Hydroponics doesn’t require a large water supply or fertile farmland for growing crops. You can grow vegetables and plants year round using hydroponic techniques. Hydroponic plants can be grown in basements, on an apartment balcony, or in almost any small space. Of course hydroponic plants can be grown in greenhouses and nurseries as well.
