We classified C. sativa subsp. indica into four varieties (in the formal nomenclatural sense, i.e., varietas). Two varieties express traits of domestication (identical to “Indica” and “Sativa” in the original narrow meanings of these terms), and two varieties have wild-type traits. We followed precedent set by Small and Cronquist (1976) who segregated C. sativa subsp. indica into two varieties – domesticated and wild-type plants. They did not place these varieties in an ancestor–progeny relationship, however, because they could not verify putative ancestral relationships.

I switched over from fabric bags to SIPs a couple years ago and have never looked back. Keeper cuts that were yielding 140 grams per plant suddenly increased to 230-250 grams, the resin content was greasier and increased as well. The plants vegged a lot faster and plant health increased. I had...

We followed precedent set by Small and Cronquist (1976) who segregated C. sativa subsp. indica into two varieties – domesticated and wild-type plants. They did not place these varieties in an ancestor–progeny relationship, however, because they could not verify putative ancestral relationships.
Key to four varieties of C. sativa subsp. indica1
1. | Plants usually with a THC/CBD ratio ≥7; terpenoid profile usually lacks sesquiterpene alcohols, fresh aroma often pleasant. Plants ≥ 2 m tall in good habitats; branches flexible, diverging from the shoot at a relatively acute angle (<45° from vertical). Fresh leaves medium green in color; central leaflets narrow (length/width usually >6), lanceolate to linear-lanceolate; margins with fine to coarse serrations, sometimes biserrate. Mature female inflorescence somewhat compact (flowering stems producing small to medium “buds”), with relatively obscure sugar leaves (a high perigonal bract-to-leaf index); sugar leaves with capitate-stalked glandular trichomes (CSGTs) usually limited to the proximal half of the leaves; perigonal bracts express a moderate to high density of CSGTs. Mature achene exocarp color (beneath the perianth) often green-brown. | |
A | THC/CBD ratio always ≥7, often much more. Mature achenes usually ≥ 3.6 mm long (Fig. 3e, f); perianth mostly sloughed off, but often persistent in places (appearing as irregular spots or stripes); exposed exocarp exhibiting prominent venation; lacking a prominent protuberant base; not readily disarticulating from plant | var. indica (“Sativa” in the historical sense2) |
B | THC/CBD ratio usually ≥7, sometimes less. Mature achenes usually <3.6 mm long (Fig. 3g, h); perianth persistent (covering exocarp and its venation), with strong pigmentation in a mottled or striped pattern; with a protuberant base; readily disarticulating from plant | var. himalayensis |
2. | Plants with a THC/CBD ratio <7; terpenoid profile includes sesquiterpene alcohols, fresh aroma often acrid or “skunky.” Plants < 2 m tall in good habitats, and often ca. 1 m; branches not flexible, branching sometimes nearly 90° from the stalk axis, producing a menorah-shaped habitus. Fresh leaves dark green in color, leaflets of larger leaves sometimes overlap; central leaflets broad (length/width usually <6), often oblanceolate; margins with coarse serrations, rarely biserrate. Mature female inflorescence compact (flowering stems producing medium to large “buds”) with prominent sugar leaves (a low perigonal bract-to-leaf index); sugar leaves have CSGTs extending more than half way down their length; perigonal bracts densely covered with CSGTs. Mature achene exocarp color (beneath the perianth) often a lighter shade of olive green to gray. | |
A | THC/CBD ratio <7 (almost always >2). Mature achenes usually ≥ 3.6 mm long (Fig. 3a, b); perianth mostly sloughed off (appearing as irregular spots or stripes); exposed exocarp exhibiting prominent venation; lacking a prominent protuberant base; not disarticulating from plant, and often trapped in the dense inflorescence | var. afghanica (“Indica” in the historical sense2) |
B | THC/CBD ratio often <2. Mature achenes usually < 3.6 mm long (Fig. 3c, d); perianth persistent (covering exocarp and its venation), with strong pigmentation in a mottled or striped pattern; with a protuberant base; readily disarticulating from plant | var. asperrima |
1 As emphasized in the text, the differences presented here represent unhybridized plants, before extensive recent hybridization between them. | ||
2 Historically, as discussed in the text, “Sativa” formerly represented landraces of South Asian heritage, and “Indica” formerly represented Central Asian landraces. This key is not intended for the identification of “Sativa” and “Indica” strains commercially available today. |

Two kinds of drug-type Cannabis gained layman’s terms in the 1980s. “Sativa” had origins in South Asia (India), with early historical dissemination to Southeast Asia, Africa, and the Americas. “Indica” had origins in Central Asia (Afghanistan, Pakistan, Turkestan). We have assigned unambiguous...

- Converting nutrient analysis to composition
phosphorus and potassium elements as follows:
- P2O5 consists of 56.4% elemental oxygen and 43.6% elemental phosphorus by weight. Therefore, the elemental phosphorus percentage of a fertilizer is 0.436 times its P value.
- K2O consists of 17% oxygen and 83% elemental potassium by weight. Therefore, the elemental potassium percentage is 0.83 times the K value.
So, for example, an 18−51−20 fertilizer contains by weight
- 18% elemental nitrogen,
- 0.436 × 51 = 22% elemental phosphorus, and
- 0.83 × 20 = 17% elemental potassium.
