Proper air circulation will help maintain temperature and humidity, and also bring down odor. Ideally, air needs to move through a garden every few minutes, and you should create a vent to the outside. Oscillating fans, and intake and exhaust fans can move air through your garden quickly, taking odors out with them.
Odor becomes much more difficult to manage in the final six weeks of a marijuana plant’s life, when trichomes and terpene production ramps up. You can also get odor-absorbing gels, which replace weed smells with other scents. Keep in mind that odor gels don’t eliminate odors, but simply mask them.
For small spaces or tents, clip-on fans can be attached to structures like walls, corners, or support beams. For larger grow rooms, use medium-sized oscillating fans or big floor models.
Inevitably, there will be fluctuations of temperature and humidity in your cannabis garden. These fluctuations can occur both throughout a grow space as well as within pockets inside a given room. They can also occur at different points within a given day or throughout a season as conditions change in the environment outside your grow space.
Make sure air is circulating through your garden

So when growing weed indoors, you can control the size of your plants by flipping them into flower whenever you think they’re big enough in the vegetative stage.
Light emitting diode (LED) technology has been around for a while, and they are getting more efficient all the time. The main drawback to LED grow lights is their cost: well-designed fixtures can cost 10 times what a comparable HID setup would.
Check temperature and humidity levels
HID (high-intensity discharge) lights are the industry standard, widely used for their combination of output, efficiency, and value. They cost a bit more than incandescent or fluorescent fixtures, but produce far more light per unit of electricity used. Conversely, they are not as efficient as LED lighting, but they cost much less.
But the benefits are great: LEDs last much longer, use far less electricity, create less heat, and the best designs generate a fuller spectrum of light, which can get bigger yields and better quality.
This is kept on a timer and can be adjusted to suit the needs of the plant.
Now, add the nutrients to the solution, and if needed make sure air will be getting into the water via an aquarium bubbler. Run that, make sure everything in working order, and check the balance of the water.
Ebb and Flow
As the plants absorb the water, the tanks reservoir will slowly lower and need to be refilled. The water should be brought back up to level, without adding any more fertilizer or nutrients to the mix. The water is evaporating, but all those compounds are not and will remain in the water at an appropriate level.
How to Begin
In general, a hydroponic grow won’t differ from a standard grow in most ways, aside from considerations needed to keep the tanks full and the room from getting too wet.
