flowering from seed

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!

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.

The 12-12 lighting technique makes the grow cycle 7-9 weeks in general, rather than the much longer time needed when giving plants a vegetative phase. For the space constrained, and those willing to experiment and give it ago, it can be a dream come true.


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.

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.

There are some haters of this method, but many love it. Those who hate on it often have not actually tried it. It is all about giving it a go and seeing what works for you. Even if you decide against it after trying it, it all helps expand your knowledge as a grower.

Growing with a 12-12 photoperiod is a solution to space and resource problems. This method eliminates the vegetation phase of growth and forces the plant to go straight into flower from a seedling. Yields are lower than that of a regularly grown cannabis plant, but results are obtained much faster, with a few advantages.

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.

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.

These are perennials in some climates with a long blooming period from around July to September. They’re good for flower borders, as well as for use as cut flowers. Plus, they’re efficient at spreading, so you don’t have to plant many seeds to establish a large garden bed. Make sure you have good soil drainage, as soggy soil can be fatal. And remove the spent flower heads to encourage further blooming. Plus, after flowering is complete for the season, cut back the stems to their lowest leaves to conserve the plant’s energy over the winter.

Sunflowers (Helianthus annuus)

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.

These flowers have a lovely sweet fragrance and bloom from around April to June. You can sow the seeds directly in your garden a few weeks before your final frost date, or start them indoors roughly six weeks before your projected last frost. The plants will decline in the summer heat, during which you can cut them back by about half. This might promote additional blooming in the fall. Or you can sow more seeds in August for fall-blooming plants.

You can be nasty to nasturtiums, and these hardy flowers will tolerate your neglect. The leaves and flowers are edible and often added to salads. But they’re perhaps more popular as a cut flower because of their lovely fragrance and beautiful colors. Nasturtiums can tolerate poor and dry soil, though you should water them during extended dry spells. And protect them from the afternoon sun in hot climates. Plus, skip the fertilizer, as too much richness in the soil can actually inhibit blooming.

These flowers grow as perennials in warm climates but can work as annuals elsewhere. Make sure the threat of frost is behind you before directly sowing them in your garden, or start them indoors. The flowers open in the afternoon, hence their name, and they have a lovely fragrance. They bloom from mid-summer to fall and are fairly low-maintenance beyond preferring consistently moist soil. So be sure to water your flowers during dry stretches.

6. Drop 1 or 2 seeds into each hole.

5. Make holes in each cell using your finger, a pencil, or a dibbler. A general rule is to plant the seed to a depth twice its size.

9. Cover trays with a clear plastic dome and set onto a 70°F (21°C) heat mat or in a warm corner of the house, consistently above 65°F (18°C).

1. Before you get started, it’s important to gather the proper supplies. You’ll need potting soil, seed trays, pots, bottom trays, vermiculite, clear dome lids, shop lights, and plant tags.

10. Check trays daily, and once seeds have sprouted, remove plastic dome lids and move the tray off the heat mat to a bright space, such as a greenhouse, or under florescent lights. If using lights, make sure they are suspended a few inches above seedlings and put them on a timer, making sure to give plants 14 to 16 hours of light a day. As the plants get taller, be sure to keep raising the lights so that they are 2 to 3 inches (5 to 7.6 cm) above the tallest plant.
