Also, check for eggs and tiny bugs underneath the leaves. Dip new clones or small plants in room temperature water treated with Safer Soap or Mighty Wash. If you can’t dip the plant, spray with a proven spider mite cure.
Keep new plants in quarantine for at least a week and check regularly to ensure they have no bugs before you bring them around your other plants. If you’ve visited another cannabis grower, grow room or outdoor garden, it’s especially important to change your clothes and possibly shower before checking on your plants. You don’t want to infect your plants with spider mites that are already specialized in infecting cannabis plants! A healthy population of predatory insects like ladybugs will help kill off pests including spider mites. The “Western Predatory Mite” is another great defense against spider mites since they specialize in killing mites. Only use pesticides if you actually need them and avoid using broad-spectrum pesticides that kill lots of bugs indiscriminately. Instead, try to use narrow-spectrum pesticides that are meant to kill just the bugs you’re trying to get rid of. So for example, if you have caterpillars, use something that mostly kills just caterpillars (like BT Spray which pretty much only kills things like caterpillars and fungus gnats) instead of using a pesticide that kills all kinds of bugs including caterpillars.
It will not only work better to get rid of the specific pest you’re having trouble with, but it also prevents you from possibly killing some predatory insects that may be protecting your garden. They Look Gross But They’re Already Eating Bad Bugs! Make sure you have the proper ground cover (cover your soil with a soil cover, weed barrier fabric, Diatomaceous Earth, or some other barrier). Basically, you want to prevent anything from being able to live or grow in the soil near your plants Make sure your plants are growing in a breezy area that doesn’t get too hot – spider mites love hot weather and stagnant air. In addition to attracting pests, stagnant air can also trigger different types of mold, especially in the flowering stage! Keep a close watch on your plants, and react quickly at the FIRST site of spider mites. Cannabis growers that understand the cannabis life cycle and can tell the difference between male and female plants before flowering will always enjoy more success than the witless weed grower. Pistils can tell you a whole lot about your cannabis plants. In this blog, we take a closer look at why they are so important. To the ordinary decent home grower, a pistil is a hair that protrudes from a calyx on a female flower. When a pistillate hair comes into contact with pollen from a male cannabis plant, it is then pollinated. Instead of focusing on producing more resinous flowers the female cannabis plant begins to develop seeds. The cannabis will be less potent, and seeds will form in the bracts that contain the ovule. Sensimilla, which means seedless, is entirely dependent on female cannabis plants not getting pollinated. WHAT CAN A PISTIL TELL YOU ABOUT YOUR YOUNG CANNABIS PLANTS? Typically male cannabis plants will develop preflowers sooner than their female counterparts in the cannabis garden. 3-6 weeks post germination you should be able to confirm that your feminized photoperiod seeds really are all females even if they are still in vegetative growth. Likewise, if you have regular seeds, you should be able to identify the male plants for removal before flowering. Pistils tend to poke out from nodes pretty randomly on young cannabis plants. Carefully inspect your cannabis plants and you will spot preflowers sooner or later during vegetative growth. Sometimes they are obvious, close to the top of the plants and easy to spot. But this is not guaranteed so really examine the plants carefully. Beside a stipule which is itself a green hair like growth on the stem, you will see the preflowers. You are hoping to see a wispy white hair at the node. If you see any kind of ball and no hair you’ve got a male. Until you can see a white hair emerging from a few nodes you really can’t be sure you’ve got a female cannabis plant. You may have to wait as long as 8 weeks of vegetative growth with some strains to confirm female cannabis plants. However, after 4-6 weeks most growers can at least weed out the males.
And keep an eye on one or two uncertain plants in early bloom if need be.
WHAT CAN A PISTIL TELL YOU ABOUT YOUR MATURE CANNABIS PLANTS? Autoflowering cannabis plants tend to suddenly erupt with flowers quicker than you would expect. Somewhere between day 15-35 post-germination, your feminized autoflowering cannabis seeds will have multiple white pistils bursting forth from the first flowers.
