How to prune your plants

CMH Gardens Plant Pruning

In CMH gardens plant pruning can help to further increase crop yields and quality.  CMH (ceramic metal halide) grow lights produce light that is very potent for plant growth relative to the power wattages they consume.  Much of this has to do with the fact that Photons (light “packages”, ie from the sun) that plants receive carry more energy when there are higher ratios of “blue” light relative to other wavelengths in the spectrum.  Whereas, common grow lights like HPS are very low in these wavelengths i.e. why you need higher wattages of HPS lights to achieve the same results versus CMH grow lights when gardening under grow lights.

Because CMH grow lights deliver such “clean” wavelengths that are absorbed by plants easily, photons don’t need to ricochet around so much before they are absorbed by the green parts of the plant for photosynthesis (where light energy is converted to chemical energy for plant growth). So, with more efficient lighting that is absorbed for growth more easily, it pays to “teach” plants where you want them to focus their energy for developing high quality, dense and heavy weight flowers and fruits. 

Let’s talk more about CMH gardens plant pruning.

Well pruned plants in CMH gardens will often yield up to 25% more than unpruned plants—with a higher percentage of AAA+ quality flowers or fruits.  Experienced growers know that few flowers of higher quality that receive strong lighting will typically weigh more than plants that have a higher number of flowers, although of lower quality because a higher percentage of the plant parts are not receiving strong lighting for denser and chunkier qualities in the harvest.

How To, CMH Gardens Plant Pruning at time of transplant

Once cuttings or seedling have been pre-vegged and are ready for transplant into larger containers, grow beds, or cubes to receive stronger lighting ie Endomaxx SUM315 CMH grow lights is a good time to start pruning in your CMH garden.  At transplant, remove all of the lower leaves and branches, just leaving a crown of leaves and stems on the upper third of a six to eight inch tall young plant.

Vegetative Growth, CMH Gardens Plant Pruning

By keeping the lower portion of the plants free of stems and leaves, the Bridge to Troubles is eliminated, ie upper parts of plants contact moist growing media.  Further, removing lower growth that is often shaded improves air circulation through the plant canopy, creating healthier and sturdier plants.

Flowering, CMH Gardens Plant Pruning

During the start of flowering, decide how many branches each plant should have at harvest time.  While it can make your garden look naked initially, removing a significant portion of lower or crowded shoots opens up the canopy to produce larger and heavier fruits or flowers on the branches that remain.  The same root system can now supply less upper mass, giving each flower or fruit more “juice” for development towards heavy yields.

By mid flowering, many strains that originate at more Northern Latitudes will benefit from removing a large portion of the wide-bladed fan leaves that shade the flowers or fruits developing along the stems of the plant.  In nature, most of these leaves would be gone by now anyways due to predation or transfer of stored nutrients into the upper more active portions of the plants.
