    How much light should I give my clones?

    The Dude

    Are you wondering how much light to give your freshly cut clones? It’s a common question, and I’ve set up an experiment to find out the best approach. Here’s what I discovered.

    The Right Light for Freshly Cut Clones

    For freshly cut clones, ambient light is your best friend. Avoid direct light until you see roots forming. Once roots appear, you can gradually increase their light exposure. When new growth begins, it’s safe to give them full light along with your other plants in vegetative growth. Stick to an 18-hour light and 6-hour dark cycle for the best results.

    My Experiment with Clone Light Exposure

    To provide a clearer answer, I set up an experiment. I cut a tray of clones and placed them in a clone dome near a four-bulb fluorescent T5 light fixture. Over two weeks, I observed how the light affected the clones’ health. The results were quite telling: leaves that were too close to the light turned yellow, crispy, and eventually died.

    Signs of Too Much Light

    If your clones’ leaves turn yellow, it’s not a sign to give them more light. In fact, they’re likely getting too much. Unrooted clones exposed to light will try to photosynthesize but can’t uptake nutrients, causing the leaves to cannibalize themselves and turn yellow. You’ll also notice the leaves cupping to conserve moisture. Here’s an example of what it looks like:

    Notice how the right side of the tray, which is getting too much light, has suffering clones.

    What to Do If Clones Are Overexposed

    If you see yellowing leaves and other signs of light stress, it’s best to discard the unhealthy clones. Stalled clones take weeks to recover and start growing rapidly again. To give your clones a quick start, keep them topped often. In about 45-60 days, you’ll have robust plants ready for flowering.

    Stay Tuned for More Tips

    Make sure to check back at Dude Grows every week. I’ll be posting step-by-step cloning instructions and tips on preparing your plants for flowering. Keeping your plants short and bushy, like the example here, will produce a wide canopy with dozens of large tops.

    By following these tips, you’ll maximize your chances of growing healthy, thriving clones. Happy growing!

      Yet another easy answer at an opportune time. I ran into an issue w two “mothers” dropped of all emergency like w no idea what’s grow’n on w any of it. No idea on soil composition or feedings or any of that… oh and they didn’t look too great either. Chlorotic patches, signs of pests, thin branches… basically the floral equivalent of an opiate addicted pole dancer, not the product of a happy and stable environment. Anywho, I get Candi back on her feet again, things are looking up, rehab is working then BAM! bitch pulls an Amy Winehouse on me, relapses back into old habits and starts to yellow on me from the bottom up, quickly. I drop in some dyna grow N2 feed, trim shit back yet again and wait. The trend continued so Im worried about lockout. The soil and what’s been tossed into it are a mystery but lockout would explain the lack of uptake. Yes, I’m going to pick up some recharge for my next go around… sigh. Hey, when you compared the soils bacteria to our digestive bacteria… yeah, when you wipe out the good bacteria in someone w say vancomycin and give them a case of c. dif where the awesome super helpful bacteria are replaced by some lazy, tough motherfucker… can that happen in the soil as well? What is the c dif of the soil… the soil dif? Anyway, back to the real point, instead of trying to flush the soil I uh… well I cut that bitch into pieces and put her in some rock wool. Im afraid I made a mistake and just lost a plant. Should I have just flushed?

        >>>starts to yellow on me from the bottom up

        A.D. My stoner translator is broken, but I think I get what you’re trying to say. I don’t think you have a lighting issue here. If you’re plant is yellowing from the bottom up, that’s usually a sign of root rot, or extreme lockout of all nutrients. Flushing agents can cause a nutrient lockout too. One common mistake a see people make, is planting a small plant into a huge pot. The problem with this, is you can’t water your plant often enough. If I were you, I would have put the plant into a smaller pot, fed a mild 300ppm nutrient solution at 7.0, with lots of run off, and then topped it off with a nice dose of Recharge. Then, let it go until the pot feels light again. Remember, your pot should feed significantly lighter between waterings. If it doesn’t, your pot is too big, you’re your watering too often. Consider lightening up your soil mix with perlite on the next round.
