The buds were too heavy and they were flopping over. As a result, they weren’t using the light efficiently and some buds were shading others.

We decided to use YO-YO Plant Supports to hold the buds upright. Small nails were used to fasten the supports overhead to a crossbeam. Then we attached the small hook on the YO-YO to a bud. The device has a spring to hold the plant upright through tension.

Photo 1: Notice one bud has been supported with plastic horticultural wire.  All the other colas are bending over from lack of support.








Photo 2: You can see all the colas are being held upright. They get best light exposure in this position.




Using this technique, it's easy to make sure that light penetrates to the lower portions of the buds because you can position the YO-YO's to open the plants up by stretching colas outward. They are very easy to use, and make the tedious task of tying and twisting go much faster, easier, and with less damage to the plants. The YO-YO's are repositionable and reusable.

The YO-YO hook easily attaches to the stem for bud suppport.

    Ed, long time since we have talked. Have you any information on current scholars looking into “reclassifying” strains from the Afghan, Paki, Bangladesh region? For instance, since there is so many Kush varieties and variation scholars want to reclassify to “Afghan strain” and distinguish from Kush???…I did a little research on “current” Cannabis identification. So far I have not been able to identify scholars in the “reclassification” of Afghan, Kush and so on. I have heard this is in progress but I can’t find one article. Thanks for your time and keep up the great work! Dr. Gene

    Current known Cannabis varities:
    The Cannabis genus is typically considered to have two species, Cannabis indica and Cannabis sativa.[1] A third species known as Cannabis ruderalis differs from the other two species in a few key ways. C. ruderalis is very short, produces only trace amounts of tetrahydrocannabinol (THC) and flowers independently of the photoperiod and according to age.
    Pure sativas are relatively tall (reaching as high as 4.5 meters), with long internodes and branches, and large, narrow-bladed leaves. Pure indica varieties are shorter and bushier, have wider leaflets, and are often favored by indoor growers. Sativas bloom later than indicas, often taking a month or two longer to mature. The subjective effects of sativas and indicas are said to differ, but the ratio of tetrahydrocannabinol (THC) to cannabidiol (CBD) in most named drug varieties of both types is similar (averaging about 200:1). Unlike most commercial drug varieties, indica landraces often consist of a mixture of plants with varying THC/CBD ratios. The relatively high CBD to THC ratio typical of hashish produced in regions where these landraces are grown (including Afghanistan and Pakistan) is useful for treating insomnia.

    In 1785, Jean-Baptiste Lamarck published a description of a second species of Cannabis, which he named Cannabis indica. Lamarck based his description of the newly named species on plant specimens collected in India. Richard Evans Schultes described C. indica as relatively short, conical, and densely branched, whereas C. sativa was described as tall and laxly branched.[3] Loran C. Anderson described C. indica plants as having short, broad leaflets whereas those of C. sativa were characterized as relatively long and narrow. Cannabis indica plants conforming to Schultes’s and Anderson’s descriptions may have originated from the Hindu Kush mountain range. Because of the often harsh and variable (extremely cold winters, and warm summers) climate of those parts, C. indica is well-suited for cultivation in temperate climates.

    In 2011, a team of Canadian researchers announced that they had sequenced a draft genome of the Purple Kush variety of C. indica.
    • Kush refers to a subset of strains of Cannabis indica. The origins of Kush cannabis are from landrace plants mainly in Afghanistan, Northern Pakistan and North-Western India with the name coming from the Hindu Kush mountain range. “Hindu Kush” strains of cannabis were brought to the United States in the mid-to-late 1970s and continue to be available there to the present day. Afghan Kush
    • Pakistani Kush
    • Af-pak (Afghan-Pakistani hybrid)
    • Hindu Kush
    • Chitral Kush
    • LA Confidential
    • Master Kush
    • Bubba Kush
    • Pure Kush (Also known as ‘Original Kush’ or ‘Kush’)
    • Vanilla Kush
    • Purple Kush
    • Grapefruit Kush
    • Lavender Kush
    • Pink Kush
    OG Kush and related varieties are not true Kush strains but indica-sativa hybrids descended from the Sativa-dominant Chemdawg strain.
