A highly effective option for growth speed and increasing yield relates to the process of foliar feeding. It is likely to take place in a well vented area that is able to benefit from the required to CO2 levels. By combining bat guano, fish emulsion, worm castings or similar plant foods and feed in the stages where the plants are progressing through the vegetative phase and flowering phase. It isn't generally suggested to include when the plants start to reach the late flowering stage. The process of using foliar should stop about two or three weeks prior to harvesting. It will benefit if you are able to clean the plant with plain water on a week by week bases to make certain that the leaves aren't left clogged. Feeding can take a place once every day or once every other day.
In most cases feeding the plants with foliar is likely to benefit in the early morning between 7 and 10 a.m., and again in the evening after 5 p.m. A reason for this is that the stomata located on the underside of the leaf are open at these times. In addition, the ideal temperature range is in the region of 72°, and at 80° mark the leaves might not open. So making use of the cooler times of the day you are certain to get the more desirable results. You might need to establish the coolest times in your own set-up, which in some situations might be 2 a.m. A spray system is able to benefit if using an atomizer to help with creating a fine mist.
Ideally, you want to make certain that a pH level is kept in the region of 6.2 to 7. If a higher pH level is required you can use baking soda, but if a lower pH level is necessary, you can add in vinegar to the medium. It can also help to rely on a wetting agent to stop the moisture beading, which might well leave the leaves burning since they might start acting similar to small prisms. Avoid spraying a hot bulb, so make certain that all of the spray work is completed when the bulbs are cool.
A more desirable foliar feeding solution is likely to include those that contain plant food and seltzer water. A combined mixture of this type is able to provide the necessary nutrients and CO2 direct to the leaves in a single spry.
The process of foliar feeding is highly recognised in the industry has been a beneficial option to ensuring the ideal nutrients are able to reach the plant life when a nutrient lockup issue might begin to limit the possible intake to the roots.
CAUTION: A significant aspect is to wash the leaves prior to harvesting and before they are able to entirely dry. If not cleaned the leaves are likely to be left with nitrate salts.
Most growers will have their own particular growth practices in place and might prefer to stick to the commercial plant foods for a more efficient growth option. Some cultivators do believe that bat guano is quite unsanitary and that fish emulsion has an undesirable odour.
Growing a harvest with an organic set-up is certain to be the more desirable option to those that want to avoid the more toxic gardens. Using CO2 on a well established hydroponic plant inside set-up can be just as effective without needing to rely on foliar feed.
