Tips on Flowering Plants Indoors

Here we answer some frequently asked questions about how to flower plants indoors.

What is the Flowering Stage?
During flowering, plants will put their full energy into a reproductive effort in preparation for the coming winter. In nature, long nights signal the plant that winter is coming and that it is time to flowers and produce seeds. The plant “senses” the longer nights by a direct interaction with light. Plants contain a flowering hormone that is sensitive to light and is rendered inactive by even low levels of light. When the dark periods are long enough, the hormones increase to a critical level that triggers the reproductive cycle. Vegetative growth ends and flowering begins.

How Can You Induce Flowering in Plants?
To induce flowering in short-day plants, the plant must be subject to at least 8 or 12 hours of uninterrupted darkness per day, though the exact period of darkness the plant needs may vary depending on the type of plant. Make sure to look up what your plants specific needs are before adjusting their light exposure. For optimal results, you will need an area that you can keep pitch dark. If the plants were measuring the dark period with an hourglass, an interruption in the dark period would be like starting the hourglass over. The lights should also come on and off at the same time each day. You will need to set your grow lights to a timer in order to accomplish this.

What Light Should You Use During Flowering?
During the flowering stage is when your plants are going to gain the most benefit from bulbs that provide red spectrum light, such as GGL’s high-pressure sodium bulb. GGL bulbs are designed to produce the warmer regions of the light spectrum in order to stimulate fruiting and flowering production. Made for use with both digital and magnetic ballasts, they also feature the highest quality ceramic burner on the market.

What Nutrients Should You Use During the Flowering Stage?
Most nutrient lines have a bloom formulation that contains all the elements your plant requires for the flowering phase, but for truly superior results, a dedicated flowering booster will have a massive impact upon your overall crop performance.  The most common type of flowering additive is a PK booster such as House & garden’s Top Booster. There are many products that add these elements into your feeding regime and they vary in strength, formulation and application

Towards the end of the plant’s life cycle, we also recommend using House & Garden’s Shooting Powder or Mad Farmer’s Mother of All Blooms (MOAB) to force plants into starting flowering a second time.  Use either product at the end of your flowering period for the last three weeks to see a significant increase in yield.

*Note: Only use Shooting Powder or MOAB when your plants are sufficiently healthy as it is a very strong agent that requires a lot from your plants.  Do not use either product in combination with any other booster.
