Marijuana Flowering Phase Success Secrets

Marijuana flowering phase is the payoff phase for growers, and we’re giving you success secrets so you get bigger, more potent buds.

Here we go…

Control Temperature & Humidity: Lights-on grow room temperatures above 74F in grow rooms without added C02, and above 83F in grow rooms with added C02, make buds airy and poorly-formed.

High temps during marijuana flowering phase stresses plants to make them suck in more water and nutrients, and to transpire more moisture out through the leaves.

When marijuana flowering phase plants suck in too much nutrients water, it creates nutrients-laden root zones that need to be flushed.

(I recommend a flush with pure reverse osmosis water that takes the place of a nutrients watering cycle every 2-3 weeks during bloom phase, starting in week three.)

Hot temperatures create extra leaf transpiration, resulting in soggy buds that are ripe for gray mold.

That’s one reason grow room humidity should be between 51-56%.

Growers use dehumidifiers, air conditioners, and/or exhaust ventilation to control humidity.

If humidity is too high, the buds can rot with gray mold, and growth slows down.

Another tip: have your lights-off temperatures be 8-10 degrees cooler than your lights-on temperatures.

And use a chiller to keep your nutrients water at 68F.

If you live in a very hot climate or are running a lot of lights in a small space, set your lights-on cycle so it corresponds with cooler nighttime outdoor temperatures.

Rotate your marijuana plants so they sit in different parts of the grow room sequentially.

This can be difficult when you’re growing with joined buckets in deep water culture systems.

But as much as possible, rotate individual plants on their axis, and rotate them around the room so they get light exposure from all sides over the course of marijuana flowering phase.

Try drought stress. This means skipping a watering cycle, but it doesn’t mean letting your root zones get so dry that your plants wilt.

If you do a flush, and then let your root zones get drier than usual, and then do a feeding, your plants will get a big jolt of nutrition.

Feed carbohydrates and B vitamins from week two to two weeks before flushing.

Use pH Perfect hydroponics nutrients made by Advanced Nutrients.

Not only are they made to boost cannabinoid production and harvest weight, they’re also made to manage root zone and nutrients water pH so your marijuana flowering phase plants can intake the nutrient elements they need at all times.

Other brands of hydroponics nutrients have inferior pH buffering, or no buffering at all, resulting in wild swings in root zone and nutrients water pH.

Experiment with combination hydroponics lighting.

Instead of just running HPS (high pressure sodium) the entire crop cycle, use mixed lighting such as one 400 or 600-watt Hortilux Blue for every 1000-watt HPS bulb.

Or add Hortilux PowerVeg T-5 ultraviolet, because ultraviolet light pumps resin production in marijuana flowering phase.

Contrary to what many growers believe, using mixed lighting in marijuana flowering phase increases cannabinoid production and bud size, as long as your ratio of red and orange spectrum, and ultraviolet spectrum, exceeds your ratio of blue (metal halide) spectrum.

Increase root zone size at the beginning of marijuana flowering phase.

I used to believe root growth only happened in veg phase.

But after several seasons of monitoring root size, I discovered that cannabis roots continue to grow at least into mid-bloom phase if not longer.

I’ve seen root gains of 10-35% in density and size during bloom phase, with most of the growth taking place in early bloom.

If roots become constricted or want to expand and have no room to expand, your plants could feel stress, and not be able to take in as much nutrition, oxygen, and water as they need.

I’ll transplant my cannabis plants from, for example, 7-gallon containers to 10-gallon containers at the beginning of bloom phase.

As long as you don’t use the too-dense root zone media, or overwater (so that the bottom section of your container is overly damp or too full of nutrients salts), the extra capacity only has benefits.

And if you decide to re-vegetate those plants, the extra capacity will be very helpful.

As you expand root size, feed roots with beneficial microbes engineered for marijuana roots, such as Voodoo Juice, Piranha, and Tarantula.

Now you have surefire marijuana flowering phase success tips. We’re happy to help you grow bigger, stickier buds!
