Mayfield G: Green Harvest
75pp UK - undated, recent.
appears in at least two virtually identical forms, the
other being "Harvest Green" by Ian
Bayram. Of the two, this version appears the more original,
with better production values.
"The material in this book is for information only.
Neither author nor publisher advocate nor encourage
the breaking of the law. Marijuana cultivation is illegal."
states "The book's prime function is to show the
reader how it is guaranteed to produce a perfect
Sensi garden every 8 weeks." (author's emphasis),
although the tone is that of improving the technique
of persons who have already tried, with limited success,
to grow marijuana.
(what is marijuana) documents the cannabis life-cycle,
and the processes and pitfalls involved in gaining experience
as a grower. Section 2 discusses security (the need
to avoid detection), section 3 whether to grow outdoors,.
in greenhouses or lean-to's or indoors, where the author
states he will show how to grow at least 9 ounces of
dried sensimilla (sic) every 8 weeks.
deals with lighting requirements, with sections on electric
gardens, the light spectrum, photoperiod (day length)
and types of light (fluorescents, metal halide, High
pressure sodium (recommends use of SON-T-Agro sodium
starts with the equipment needed for indoor growing
(1x400W HPS bulb, power cables, oscillating fan, 1x24hr
timer switch, 2x thermometer/humidity guages, 36x 3
little plastic rose pots, 1 multipack of 3" starter
pots, 80 litre bag of soil, and 80 litre bag of perlite,
plus nutrients. Section advising on soil composition
(recommended Fisons F1 in 50/50 mix with Perlite), ensuring
neutral pH. Section on watering, advising tap water
should be stood to reach room temperature and monitor
pH. Cautions against overwatering, but states that underwatering
is not a serious problem. Section on nutrients (fertilisers)
with a confused account of NPK (nitrogen, phosphorus,
potassium) values, and changing needs of plants. Admits
little knowledge of the scientific aspects. Section
on ventilation, fans, extractors and CO2.
Section on the size of garden and necessary light density,
and potential running costs.
starts by discussing seed selection, including Dutch
hybrids such as Skunk, Northern Lights,
Shiva Shanti and Red Hair. Recommends
Northern Lights and Skunk. The next section is on sexing
the plants and production of sinsemilla. The next section
advises on germinating seeds (tissue paper), and another
section on nutrients.
- the first section gives advice on construction of
a growers box, about 1 metre square and 5'6" to
6"0" high (author's mixture of imperial &
metric measurements), as well as a box approximately
24" high for propagating cuttings. This construction
has many similarities to Marlow's Kushti Box. Describes
temperature control and air circulation, fans and heaters.
The recommended method of growing is to take cuttings
from "mother" plants, root these, and at 6-7
weeks after rooting transplant these to the flowering
chamber, and take fresh cuttings. Section on flowering,
including pot size, temperature and day length. Advise
flowering for 6 weeks, and then feed only water before
harvesting two weeks later.
covers drying techniques, and problems with pest such
as insects and plant disorders. A discussion of hermaphrodite
plants, THC content (no figures, but recommends Dutch
varieties) training and pruning of plants. A brief section
on alternative fertilisers and lighting, and a final
section explaining the philosophy of keeping the book
simple, and a call for cannabis law reform.
The book bears remarkable similarity to Tricameral Sinsemilla,
in that it recommends indoor growing, purpose built
wooden boxes similar to the Kushti Box, and a short
growing cycle. Neither book mentions hydroponics, both
recommending organic soils. The main difference is that
Tricameral suggests a much more gradual transfer
of plants between the main stages (growth or flowering)
whereas Mayfield suggests an 8 week cycle harvesting
the entire contents of the flowering room at the end
of each cycle. The styles are also similar, keeping
technical matters to a minimum, and with a conversational
