Summary & Conclusions
Pros:
Fairly easy to grow overall, once nute requirements are unserstood.
Very resistant to low humidity and water levels.
100% germ rate.
Strong growth, especially roots.
Responds well to LST (and presumably ScrOG), so is very good for small spaces.
Cons:
Considerable differences in phenotypes, which...
Require different nute levels.
Grow to different heights if untrained.
May catch beginners unawares.
Two different phenotypes observed:
Type A: As per Nos.8 & 10. Classic
indica: Short and bushy plants with shorter, chubbier leaves. Deep green colour. Males may not show, or grow more rapidly until 12/12, but then develop quickly. Easy to overfeed, especially with Nitrogen, which may be responsible for observed leaf rash in this and other Hashberry grows, along with other N-tox symptoms as generally noted elsewhere. May benefit from long veg times (5-6 weeks). Slight reddening of petioles, once in 12/12. Less apparent resin production, but still moderately high on visible leaves. May show second, late burst of flowering activity in Week 7-8 of 12/12. Very tight, dense buds - good ventilation and air movement recommended in 12/12 to discourage mold.
Type B: As per Nos.1 & 3. Taller than A. More
sativa looking, with slenderer leaves, longer internodes and faster growth. Lighter green than A overall, but older leaves turn the same deep green. Could be mistaken for male in veg, due to fast growth, but males can show sex very early (<21 days). Require far more nutrients than Type A in 12/12 and perhaps earlier, if vegging for long periods. Considerably redder petioles than Type A, especially once in 12/12. High resin production, extending to bases of larger fan leaves. Moderately dense buds.
Other:
All plants initially seemed thirstier than previously grown strains (+30-50%), especially after one week of 12/12. However, water uptake was very much reduced in the last two weeks of flowering.
All plants showed hermaphrodism, probably throughout the 12/12 period, although this may have been due to environmental stress.
Some type Bs (
e.g. No.1) may look like Type A until 12/12 starts.
