flowering from seed

Always be sure to re-sterilize your grow space after each crop.


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.


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.

Force flowering marijuana from seed can provide excellent quality, resinous flowers, all the while saving space, time, and money. For those with space constraints, it is a win-win!

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.

Annual flowers are the backbone of billowy cottage gardens. Many annuals will seed themselves, so all you have to do is leave the flower heads on the plants at the end of the season. They will eventually drop seed, and the seeds will weave themselves throughout the garden with a little help from the wind. You may sometimes end up with too many seedlings in one spot, but they should be easy to pull or transplant.

You’ll need to keep your eye on the wildflower area for balance between species (overseeding the species you want, annually, can help). Any perennials in the mix may not sprout the first year. Weeds will want to encroach while the area becomes established too, so you’ll need diligence in your efforts to pull those. Just remember, the results of your efforts will be well worth the work to establish the wildflower garden.

Growing Annual Flowers From Seed

Not all seeds know it’s time to sprout just because they’re planted in soil. Some need a signal that it’s time to germinate, either from a change in temperature or moisture levels, or an increase in light. To trick your seeds into germinating sooner than they might typically, you can use one of the below methods:

Remember that hybrid plants will not grow the same as their parent plants (a pink flower may get you red and white plants the next year, for example), but heirloom self-pollinated plants will grow true (just like their parents).

Do you want to enjoy a beautiful flower garden without spending a ton of money? You can save money on flowers for your garden by buying more seeds and fewer plants. Perennial flowers grown from seed might not bloom during their first growing season, so it’s important to have a little patience with them. On the other hand, annual flowers should bloom as they go through their lifecycle over a growing season, and some annuals might even self-seed to grow new plants the next year. Here are 14 flowers that are among the easiest to grow from seed.

The showy flowers of these spring- and early summer-blooming perennials come in many colors. Allow them to self-seed, and they’ll come back year after year with minimal maintenance from you. Columbine can tolerate a variety of growing conditions, but make sure your plant isn’t sitting in poorly drained soil. Also, if you remove the stems after they’re finished flowering, you can prolong the plant’s blooming period.

These annuals are climbers and make nice cut flowers. They do best in cool soil and will decline in hot, humid summers. Start seeds indoors six to eight weeks prior to your final frost date to maximize the plant’s blooming period before the hot weather takes hold. Keep the soil evenly moist via rainfall and supplemental watering. And add compost or fertilizer during the growing season, especially if you have poor soil.

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.

This vine is often grown on trellises or arbors. It is an annual, and when started from seed it can take until the end of summer to bloom. However, if you start the seeds indoors about six weeks before your projected last frost date, they’ll start blooming earlier in the growing season than if you directly sow them in your garden. Once the plant is established in your garden, it will self-seed and come back on its own year after year. Water your plant around once a week to ensure even moisture, and use a low-nitrogen fertilizer monthly or as needed during the growing season.
