Winter Hydroponics Indoor Gardening for Maximum Yield

Winter hydroponics can be warm and sweet for you. Winter hydroponics can be warm and sweet for you.

In our previous discussion about winter hydroponics gardening we talked about your cold weather indoor gardening strategies…when interior garden heat is in some places a blessing rather than an expensive curse.

We noted that the build-up of heat that requires air conditioning, venting, cooled HID lighting, cooled C02 generators and venting during warm months is not as big of a problem in winter hydroponics gardens. In fact, the opposite can be true, with the lower third of your grow room, your hydroponics reservoir water and your hydroponics grow room floor too cold for your plants.

In general, too cold means below 68F. The most common problem related to winter hydroponics is when cold air in the root area and/or cold nutrients water temperatures shock your roots while also slowing nutrient absorption and growth.

Related problems occur when your hydroponics room, floor and nutrients water fall below 68F. This stresses your plants, making them less able to deal with diseases and pests. The double whammy is that the cold temperatures provide an environment in which diseases, pests and harmful fungi flourish. You have weaker hydroponics plants and more things that attack them- not a great combination.

Being diligent as a grower who wants hydroponics maximum yield means you’ve taken steps to upgrade your grow room climate control, air mixing and root zone temperature so your winter growing continues to provide you the huge harvests you want. You make sure that your indoor hydroponics garden has ideal temperatures from floor to ceiling. This means 68-74F, unless you’re adding C02 to your atmosphere, in which case your temps can go higher.

But winter is not only a time of handling colder outdoor temperatures to make sure they don’t hurt your indoor plants. It’s also a time of opportunity. You can save on electricity costs by sending your HID heat into the rest of the house or using it to keep your hydroponics garden at its optimum 74F.

In most parts of the US (other than the Pacific Northwest), humidity is lower in cold weather than in summer, which is good news if you’re growing hydroponics plants in areas where spring and summer ambient humidity goes higher than 60%.

In a climate-controlled drying room environment with 50% humidity, temps between 65-75F, darkness, gentle air circulation, contaminant-defeating filtration and adequate air exchange, winter is a great time for you to use a hydroponics drying rack like the Quick Cure to get just the right curing for your valuable flowers.

In warmer months, you often have to provide air conditioning to keep your drying/curing environment in the optimum temperature and humidity range. Why? Because temperatures over 74F, and especially temperatures over 84F, cause degradation of essential oils and too-fast drying that decreases the quality and value of your crops. High humidity creates a nice environment for molds and fungi to attack your drying flowers.

Winter will be over in about 7-12 weeks. Have you considered an outdoor garden in some safe locale? Savvy growers who have access to safe outdoor areas often stock a remote outdoor garden with plants. Of course, outdoor plants are more susceptible to environmental hazards and thieves, but if you get a successful outdoor season, you win big, because outdoor plants can get huge!

In a few days, I’ll be discussing how you get started on an outdoor garden early by using your hydroponics indoor garden to get a set of plants ready for outdoor planting when spring arrives. Until then, stay warm, but not too warm, and enjoy your indoor hydroponics summery environment while the cold weather rages outside!
