Growing cannabis clones indoors

Watering is something that many new plant parents struggle with. Are you giving too much? Too little? Should it be reverse osmosis or filtered? For new cannabis growers, it’s best to start off simple.

You might also need to adjust the pH since this is vitally important to your plant’s overall health. Cannabis plants like a pH of 5.8 to 6.2, so investing in an inexpensive pH solution and a testing kit is important for keeping your plants happy.

The easiest option is starting with a clone, a cannabis seedling that has been cut from a more mature female plant. All you’ll need to do is purchase one from a dispensary and bring it home. Another advantage is that clones take the guesswork out of sexing, since all clones are cut from female plants.


What about frequency? If you’re growing in soil, stick your finger in to about your first knuckle. If it feels moist, you don’t need to water yet. Wait until it’s dry to the touch. Other grow mediums like coco coir are a little trickier as far as frequency and effort. Coco requires what is called “fertigation,” which is fertilizing plus irrigation. Since coco doesn’t hold on to nutrients the way soil or hydroponic solution does, you need to feed your plant every time you water. You will be watering frequently with coco, even when it’s still wet.

“As far as any equipment goes to improve growing success, it’s definitely going to be grow lights. Everything else is gravy as you look to take it to the next level, but it’s definitely not necessary. It wouldn’t make any sense to invest in anything other than a light as a first equipment purchase,” advised Jimmy.

Bryan Mitchel of cannabis cultivation equipment company Plan C Design recommends picking up a water analysis kit at your local hardware store. “Be sure to look at the chloramine and chlorine section. Chloramine is harmful to a plant’s roots and needs to be filtered out of the water before use with a KDF (kinetic discharge flux) filter. If your chlorine levels are more than 30 ppm (parts per million), let the water sit overnight with an airstone in it,” he explained.

What about seeds? While they take more time and work than clones, seeds have some great advantages. Chances are you’ll have a lot more choice when shopping for seed versus live clones. There are many seed retailers out there, most of which sell online and can ship right to your door. Each of these seed retailers will probably carry a much wider variety of genetics than a dispensary offers.

Remember, a common mistake newbie growers make is to overwater plants.

This is easily achieved by placing an exhaust fan near the top of the space to suck out warm air—warm air rises—and adding a port or passive fan on the opposite side of the space near the floor to bring in cool air. A complete air exchange throughout the entire grow space should occur once every minute or so.

For example, it takes less time to grow 3′ weed plants than 5′ plants; in the span of a year, you can maybe grow four harvests of 3′ plants, or two harvests of 5′ plants.

Make sure all equipment is on, no breakers have flipped, and everything is running smoothly. Check lights, timers, fans, dehueys, ACs, and anything else that plugs into the wall or has a battery.

Below is a list of things to consider and equipment you will need to purchase to get started growing marijuana indoors.

So when growing weed indoors, you can control the size of your plants by flipping them into flower whenever you think they’re big enough in the vegetative stage.

If you’re growing in a cold, wet basement, you might have to run a dehumidifier or heater to stabilize the environment. Conversely, if your space is too hot, you might need to add extra fans or an AC to cool the plants down.

You’ll likely yield about the same amount of weed in both cases, but more harvests mean you’ll have fresh weed to smoke more often and have more opportunities to grow different strains. But more harvests also means more work in cleaning up the space between harvests, trimming, etc.
