How can you see when to flush @Gelato93weed,

@Posse, Flushing is a term we often hear in cannabis growing communities. You've been told that flushing is essential for your plants, but you still don't understand how to do it correctly. Flushing is easy to perform and can make your roots healthier, as well as leaving you with a much tastier product after the harvest. This article shows you how it's done. What is flushing? The concept of flushing is no different from how we normally understand it. Flushing uses water to remove a buildup of material. Healthy cannabis cultivation typically requires the addition of fertilizers, many of which contain mineral traces that accumulate in the substrate and plant throughout the cycle. Flushing concept The flushing process helps remove any excess nutrients by "washing" the roots. Pure water is given and allowed to flow over the roots until it drains out. Any residue of mineral salts and salts is expelled from the growing medium, meaning the plant can deplete its remaining nutrient reserves before harvest day. Flushing usually occurs about two weeks before the end of the flowering period, but it depends on the growing medium and how heavy the feeding schedule is. The only case in which we advise against flushing is if you are growing with super organic soils, which contain a lot of microbes and beneficial organisms that can be washed away by adding too much water. Why is it important to flush? Cared-for cannabis buds Even though some people might disagree, flushing your cannabis plants is essential if you've given them chemical nutrients. Cannabis that hasn't been properly flushed can have a harsh taste and release a harsh smoke that doesn't burn well. It's worth putting in the extra effort to ensure your buds are free of nutrients. Most non-organic cannabis nutrients are chemically synthesized. This doesn't necessarily mean they are harmful to smoke, but your weed will taste much better without them. Feeding cannabis plants up until harvest day means that larger amounts of those minerals are still present in the plant when you harvest. We want to help the plant remove them so that we (or others) have a delicious product to smoke in the end. How to dry and cure cannabis buds Related story How to dry and cure cannabis buds Flushing can also be helpful when your plants receive too many nutrients. Overloading your plants with fertilizer can cause nutrient lockout, meaning the concentration of minerals around the roots is too high for them to function properly. As a result, they are unable to absorb efficiently. Heavily fed plants can also suffer from nutrient burn. With commercial nutrients being so highly concentrated, nutrient lockout can be a serious problem. In the case of burn or nutrient lockout, flushing the medium with properly pH'd water can help remove the buildup so you can continue with the feeding schedule. This is why some growers make it a habit to flush once or twice during the growth cycle, regardless of whether salt buildup or nutrient lockout is an issue.

How to flush cannabis plants Trichomes on cannabis bud As mentioned earlier, the flushing cycle should start about 2 weeks before the planned harvest. It's up to you when to start, but if you've used a very light feeding schedule, it might be a good idea to start flushing a bit later. On the other hand, if you start flushing your plants too early, they may not produce as much, so make sure your plants show signs of ripening beforehand. Check the trichomes to see if they are changing color or becoming cloudy to gauge when it might be the right time to start flushing. Once about 10-20% of the trichomes have turned milky, a cannabis plant will be nearing harvest day, meaning you can consider starting the final flush. Flushing in soil and hydroponics Flushing cannabis plants is an easy process and can be completed in 4 simple steps. The idea is to give a heavy initial flush and then provide water for the rest of the cycle. Flood the container or growing medium with stable pH water (at room temperature) until it drains from the bottom. Most tap water is fine, but you might want to adjust the pH just in case. Wait 10-15 minutes. Repeat step 1. You can use an EC/PPM meter to check the runoff until the reading matches roughly the number of dissolved solids in the water (before using it for flushing). Feed the plants only water until harvest, waiting for the medium to dry out almost completely between waterings. medium Flushing time pH Soil 2 weeks 6 - 7 Hydroponics 3-7 days 5.5 - 6.5 Coco Coir 1 week 5.5 - 6.5 Compost / Super Soils 0 days 6 - 7 Some growers skip the first step and go straight to feeding water. It depends on how early you start flushing in relation to how many nutrients have been given. There's a risk of overwatering your plants at this stage, so make sure you have a clear idea of how much they're drinking beforehand and don't overdo it. We want to be sure not to invite mold into the garden by keeping the environment too humid, especially at this stage. How to prevent mold on cannabis plants Related story How to prevent mold on cannabis plants Flushing in hydroponics simply requires adding fresh water (pH 5.5-6.5) to the reservoir for the last few days of flowering. Again, it depends on how heavy your feeding schedule has been. In hydroponics, there is no medium for salt buildup, so when we flush the plants, they are immediately cut off from any nutrient source other than what remains in the reservoir. It takes time for the minerals to be completely rinsed from the medium. Tips for flushing cannabis Overfed cannabis plants can show green foliage Growth stage - It can be a good idea to flush whenever there is a drastic change in nutrients. For example, the transition between the vegetative phase and the flowering phase is a time when feeding needs are likely changing. Flushing before introducing the new routine can give the plants a fresh start. Additionally, you'll have a clearer idea of nutrient levels in the medium and help maintain a stable pH. Enzymes - Minerals and salts are compounds that can become rock-solid, making them difficult to move. After long feeding schedules, enzyme supplements can be helpful in breaking down large nutrient salts into smaller molecules to help remove them from the medium. These can be very useful at the end of the flowering period if the leaves still appear excessively green (normally dark green from overfeeding). They prevent the roots from absorbing more nutrients by thoroughly cleaning the
