Hydroponics Light Transition Tips During Veg to Bloom

Light transition and flowering

Light, an essential and fundamental unit of life plays a crucial role in the growth of all flowering plants including your high-value crops. Duration and exposure to the daylight influence overall productivity and yield in your plants. Though the majority of photosensitive plants respond to change in wee hours and start flower production after the onset of prolonged dark cycle. However, an indoor grower can implement certain procedures to create this seamless transition from veg to bloom and minimize stress along with producing a higher overall yield.

What does light do to your plants?

Your high-value plants follow a very strange growth pattern and start production of flowers rich in THC as season changes from summer to autumn. Most pro-growers will fuel the transition from veg to bloom by reducing wee hours from 18/6 to 12/12 each day. Maximum hours of light during the veg phase make the plants sturdier and harder.  Likely when the length of the day is reduced to about 12 hours, plants start bud formation and flowering. At this stage, an essential thing to consider is that no light must reach the plants throughout the dark hours. Any changes in the light intensity with a decrease in daylight and increase in nighttime prompts the flowering hormone to be active, triggering the plants to early Bloom (flowering) phase. Such irregular light patterns and pre-shifts can cause stress, resulting in hermaphrodite’s species. Some of the varieties need 8 hours of the dark cycle to start flowering while other types need up to 13 hours to do so.

Grow lights

Fluorescent or metal halide lighting is suitable for clones and seedlings. The most commonly used lights are sodium or metal halide HID lamps. Metal halides are active in the blue spectrum of light which is appropriate for vegetative growth while sodium lights are strong in the red spectrum, suitable for flowering. Another popular type of grow light is LED grow lights which focus on both blue and red spectrums, making it suitable for every stage in a plant’s life cycle. Grow lights enable growers to increase their growing season and not just be limited to a certain time frame of the year. It also gives growers a significant amount of flexibility in the growing process. Because the grow cycle is dependent on the hours of light plants, receive, artificial lights allow indoor grower to begin the flowering process at any time they demand. For indoor gardening, artificial lights play a key role and contribute towards high yield.

One of the most imperative developmental changes a plant experiences is the switch over to flowering from vegetative growth. This transition requires a wholesale shift in lights. Given the biological significance of this transition and the horticultural curiosity in understanding as well as controlling the timing of daylight, the events that lead to flowering can be monitored and regulated.

Bloom Stage or flowering stage

The most awaited and exciting moment for growers is to see their baby plant blooming. It follows the vegetative phase; wherein your high-value plant is about to begin budding. The flowering time is very crucial because failing to fulfill their nutrient and light requirement can lead to poor bud quality as well as harvest. The duration from flowering to harvest differs from one species to other.

Initiation of Flowering

Always remember that the requirements of plants change when they enter blooming phase. And if you are smart enough to know and provide your plants with everything they need, then big and juicy buds laden is your reward! The two factors that determine rate and quality of buds produced are nutrients, light and the genetics of the plant. We give you an insight on this below:

  1. Nutrients Needed

The first two weeks of the bloom phase require high amount of potassium and phosphorous. Look for nutrients containing Ascophyllum nodosum (sea weed extract) as it enhances flowering. Secondary nutrients are additionally given to prevent diseases and promote strong roots. To get rich and big buds, you need to feed you plants amino acids, vitamins, and sugars. Carbohydrates when present as glucose, maltose, xylose, dextrose, and arabinose not only serve as an energy source but also form a wonderful substrate for beneficial bacteria and fungi present in root zones. Also, check for hydroponic formulas containing good quality of molasses as the key ingredient.

  1. Light Cycle

If you have exposed your plants to 24 hrs or 18/6 hrs of light cycle during the vegetative phase, then it’s time for a change.  Plants grown indoors require 12 hours of light and 12 hours of complete darkness (12-12 lighting). Remember to keep the lights turned off throughout the dark period. An HPS light source emitting reddish light would trigger the bloom phase. This adjustment is made when your plants are in full flowering process and can take the shade of 12 hrs darkness. Expose your plants to 14 hrs of light during the pre-flowering phase.

  1. Humidity

Keep the humidity of the grow room below 45% during the flowering stage. High humidity promotes growth of mold on buds as plants soak the excess moisture through the leaves.

 Stages of Flowering

  1. Pre-Flowering Phase

The fourth week (approx) of vegetation is usually considered the pre-flowering time. You can identify features of a male and a female with the help of a magnifying glass. If you have grown from mother females, then your plants will show primordial flowers with a little green seed pod and two fuzzy V-shaped hairs poking out of it at stem junctions. This marks the pre-flowering stage.

  1. Full Flowering Phase

Your plants proceed to full flowering phase after one or two weeks and in this phase you need to set up the 12-12 light cycle. The white hairs or the pistils will turn red or dark brown and then develop into buds, which subsequently mature. Feed your plants nutrients formulations containing appropriate nutrient solutions.

That was all about the blooming phase. Take care of your plants, provide them good light and nutrients to get big, juicy, aromatic and tasty buds. Good Luck and read more helpful indoor growing articles at our blog.
