When the top inch feels dry to the touch, water your plants well and remove runoff water. Avoid watering too often! You should be watering vegetative plants every few days. If they’re drying out in less than a few days, transplant to a bigger pot or give more water at a time. If they’re taking more than 3 days to dry, give less water at a time until they’re drinking faster.
Here are two plants right after they are given a 12/12 light schedule. Notice how both get taller, but one gets far taller than the other. The amount of “stretch” after the switch is determined by strain/genetics. Hopefully this animation gives you an idea of how plants develop in the flowering stage from 12/12 to harvest. Learn more about growing different strains together.
At this point put the buds in quart-sized glass mason jars, filling them about 80% full. Open jars daily and make sure the buds don’t feel wet or stick together. After the first 2 weeks you can open jars just once a week or less.
I personally think grow tents are a cheap (under $100) and easy way to set up the perfect grow environment, but there are lots of great places to grow!
Trim off the extra leaves and hang buds upside down in an enclosed space like your grow tent or a closet.
When your plant has reached half the final desired size, it’s time to tell it to start making buds! After you do this step, your plant on average will about double in size (more or less depending on the strain), so don’t wait too long!
It’s hard to be patient for harvest after week 6 because eventually the plant stops making much new vegetative growth while buds fatten and mature. You usually aren’t seeing a lot of new growth any more, so it might seem like buds are done. But even though you might not see it, your buds are getting bigger and more potent each day!
At this point your main job is to water your plants and check the pH regularly (to prevent nutrient problems). If you are using high levels of nutrients and supplements, try to give plain water sometimes to prevent nutrient build-up.
The first few weeks after the switch to 12/12, your plant will be growing fast! This extra fast growth period is known as the flowering stretch.
This is a super-condensed version of our Beginner Guide! The following tutorial is very basic, but if you follow the 10 steps you will get to harvest!
