When planting into the ground, make sure not to crowd your plants so their roots don’t run into each other.
Again, the first transplanting should occur after the seedling has sprouted its 4th or 5th set of leaves. To transplant:
Number of leaves
For example, you could go from a 1-gallon to a 2-gallon to a 5-gallon, or from a 2-gallon to a 5-gallon to a 10-gallon.
Transplanting gives a marijuana plant’s root system more space to spread out, allowing the plant to grow healthy and strong and to flourish.
Young cannabis plants should start in a 4-inch or 1-gallon pot. This starting pot should be adequate for a few weeks before transplanting is needed.
Obviously, no one wants to smoke seedy weed. When you grow cannabis and learn how to identify male plants and signs of pollination, you can remove these plants to save your remaining females. Likewise, recognising a pollinated female early allows you to start again before it’s too late, rather than finishing a grow that will only result in a poor-quality harvest.
Male plants won’t show hairs at these nodes, but will develop little sacs of pollen. These pollen sacs will look like little balls. These balls can appear on their own or in clusters, depending how far into the pre-flowering stage the plant is. At some later stage of growth, the pollen sacs will burst open, spilling the pollen and possibly pollinating your females.
HOW TO AVOID POLLINATION OF YOUR FEMALE PLANTS
Pollination requires the presence of males or intersex (hermaphrodite) plants, which are females that will also produce pollen. The first thing you want to do to keep the risk of pollination low is to remove as many males or “hermies” as as you can. Especially during the first three weeks of flowering, it’s important to frequently check for possible male specimens in your garden.
Pollination of your female cannabis plants will make them produce seeds and spend less energy on producing quality buds. But when you recognise the signs of pollination early, you can avoid putting time and resources into a poor harvest.
Spotting male cannabis plants and pollinated females early can save you from investing further time and effort into an entire growing season that will be for naught. Most of the time, the best course of action is to get rid of the males along with your pollinated ladies and just start a new grow.
Heat stress can lead to growing problems both indoors and out.
People love their weed plants, so they think giving them more must be a good thing. But alas, it’s not. Overfeeding can lead to nutrient burn, or worse, nutrient lockout caused by accumulated minerals in the soil. In this case, you’ll need to flush your soil with water and start again with your feedings to return the pH to an ideal window. In short: don’t overdo it on the nutes!
Using the right containers for your weed might not seem like a big deal, but you’d be surprised just how crucial this variable is. Here are some factors you should consider:
10. HARVESTING TOO EARLY OR TOO LATE
The thing is, weed isn’t just weed. There are big differences in growing characteristics among different cannabis seeds. An indica autoflower will certainly behave differently than a picky photoperiod sativa. Some strains may be suitable to grow in a colder climate, while others may require a hot, sunny environment. Some strains may need lots of nutrients, while others require only light feeding. You get the idea.
Although heat, pH, overwatering, and soil are important, we’ve added the most vital point to the bottom of the list: lighting! Cannabis plants depend on light to create energy and thrive. At the end of the article, you’ll learn the best way to illuminate your plants.
If you’re growing outdoors, air circulation shouldn’t be a problem; but then, there are other things to watch out for. For one, you’ll want to protect your plants from thieves. You can do so by planting companion species to hide your crop and mask the smell. You can also select cannabis strains that naturally remain short and hidden from view.

Use some type of absorbent paper (kitchen paper, coffee filter) and place a couple sheets on a flat surface such as a plate. Put your seeds on the paper, spaced a little apart, and cover with a couple more sheets over the top. Moisten the paper and make sure to keep it damp so it doesn’t dry out. After a few days, when the seeds have sprouted 2–3mm taproots, transfer them to their seedling pots.
