flowering from seed

There is a lesser demand for resources across the boards.
You will experience only half the water consumption with less moisture loss due to evaporation, and a third less nutrients are used. CO₂ and electricity use including most peripherals are reduced by a staggering 650 grow hours annually.
Taking hours to accomplish, tipping, fimming, branch control, and mainlining are now unnecessary freeing up your most precious resource, time.

Growing 12-12 is as simple as changing the timing on your light cycles, giving your plants equal amounts of day and night right from when they sprout. The plants will look different to a cannabis plant that goes through vegetative growth. Photosensitive hormones in cannabis make the highest point the largest cola. This method all but guarantees only main bud growth on every small plant. Essentially you will be growing a cola with a few short, budded side branches – with the plant basically being a bud in itself. Be sure to stake your plants.

Keep a keen eye out for moulds and mildews as the grow space will be getting less light with more moulding opportunity in warm dark corners and creases.


Plants with less side branching and canopy spread need less space between them, increasing efficiency. As an example: 1x 15-litre pot produces one plant with a large volume and difficult maintenance issues in a cramped space. 4x 3.5-litre pots in the same sized space can produce just as much dried material with the benefit of being easier to rotate, so the whole plant gets 360-degree light. The entire crop is less hassle during maintenance as each plant is 100% accessible and physically easier to move about. There is no need for a separate sprouting and veg space or time wasted on 18-6 vegetation. The seeds can be sprouted under the 12-12 growing lights providing continual flowering plants.

Growing this way still requires all the knowledge that would be needed to flower plants with any other method, and maintenance routines still remain unchanged. After diluted nutrients, while still young, treat your plants as you would during a normal bud cycle. However, flush more often, every ten days at most, so as to avoid salt build-up in the smaller pots.

Done with expert practice and a willing strain of cannabis seeds, it is not unknown to produce 1 gram of ganja per watt of lighting. That’s an impressive 250g in 7-9 weeks for a 250W light in a small cupboard!

Everything to which you would pay attention in a normal grow remains unchanged and are still just as important. pH and water quality, nutrient mixing, pest control, grow medium conditions, EC and ppm all still play their major roles in the dankness and weight of your finished product.

Keep in mind, annual flowers tend to grow quickly, so even those you direct sow outdoors in the spring will flower at their usual bloom time or very soon afterward. Just about any of the annuals that self-sow are good candidates for starting from seed, either indoors or direct sown.

Growing Annual Flowers From Seed

Perennial flowers may not bloom their first year, but if you have the patience to wait, you can fill your garden for a fraction of the cost of buying mature plants. Annual flowers will bloom right on schedule, and many of them will even seed themselves, so you’ll only have to plant them once to receive years of beautiful blooms. If you’ve been dreaming of nonstop color, pick up some seed packets, and get started with the tips below.

Most perennial plants don’t bloom until their second year, spending their first season growing a strong root system and lots of leaves for photosynthesis. You can sometimes get around this waiting period by starting your perennial seeds in the fall and fooling the plants into thinking the following spring is “year two,” but more often than not you’ll just have to be patient.

Cultivating a long-blooming garden has another perk. At the end of the season, you can collect seeds from your plants to sow the following year. You just have to wait until the seeds or seed heads ripen. Harvest them by tapping the seed heads and having the seeds fall from them into a brown bag, or by snipping off the seed heads whole. Ensure they’re dry before putting them in labeled envelopes to store for the following year.

You’ll have to plant marigold seeds each year because they’re annuals. But they’ll bloom all summer if you keep them deadheaded (remove the spent blooms). Save some of the seeds at the end of the season, and use them to replant the next year. Flowering might diminish during the hottest part of the summer, but it should pick up again toward the fall. If you live in a hot climate, give your plants some afternoon shade, and keep the soil evenly moist.

Sunflowers don’t start blooming until late in the season, usually from around July to August. But when those giant blooms finally emerge, it’s well worth the wait. Plant the seeds directly in your garden after your final frost, ideally in a location that’s protected from strong winds. Seeds started indoors will typically flower at roughly the same time as seeds directly sown in the garden, so there’s really no benefit to starting them early. Sunflowers are annuals, so you’ll need to save some of the seeds to replant the next year. Cover a few of the seed heads with netting, so they can dry out without the birds feasting on them.

Morning Glories (Ipomoea purpurea)

These blooms are typically a bright yellow to deep orange color, and they make a nice container plant or an edging plant in the garden. Directly sow the seeds in your garden after the last frost, or start them indoors six to eight weeks prior to the last frost date. They will self-seed from season to season. If you live in a hot climate, give your plants some afternoon sun protection, and keep the soil moderately moist. Also, remove spent flowers to encourage further blooming.

These flowers make a good ground cover for a spot that gets a lot of sun. They are highly tolerant of drought and require little maintenance. They’re even deer-resistant and typically don’t have pest or disease problems as long as their soil has good drainage. Sow your seeds directly in the garden after your last frost, or start them indoors. Expect blooms starting in the summer and lasting until frost arrives in the fall. You can deadhead the flowers to encourage further blooming, or leave some of the spent blooms to promote self-seeding.

Growing flowers from seed allows you to choose from a wider variety than what’s at your local garden center. Peruse a seed catalogue to find numerous options to grow in your area.
