rules-of-thumb for the thumb-fingered

a double handful of rules-of-thumb



• one can expect to harvest approximately 1 oz of bud for each 12" of vertical growth

• to cure bud, jar it up with a hygrometer/rh meter...start with 70% rh and burp regularly, they can be dried anywhere down to 45%-55% rh and be within the smokable range, lower if preferred

• lights should be close enough that one can hold the hand palm-downwards at canopy level and NOT burn the back of one's hand


• approximate area coverage of HPS
- 150W/175W=2'x2'
- 250W=3'x3'
- 400W=4'x4'
- 600W=6.5'x6.5'
- 1000W=8'x8'

• keep soil ph between 6.3 and 6.8 for ideal growth - hydro ph between 5.5 and 6.1 for ideal growth

• below 15*C/59*F and above 30*C/86*F temps can inhibit plant growth


• keep rh @ 50%-60% during veg - lowering during flower to 40%rh or lower if possible

• plants need 12 hrs UNINTERRUPTED dark period during flowering, stick with this rule if lighting mishaps occur - just ensure the plant has 12 hrs dark or even longer to set the timing right again if lighting mishaps occur - NEVER LESS than 12 hrs dark during the flowering period

• use tipping, fimming and supercropping to increase yield

• keep certain things on-hand if possible: Epsom salts, ph down and ph up, Avermectin, Neem oil, Hydrogen Peroxide

• to flush the SOIL/MEDIUM, run ph'ed water approximately 3 times the volume of the pot EXAMPLE: flush a 5 gallon pot with 12-15 gallons of ph'ed water

• to flush the PLANT prior to harvesting, stop feeding the plant approximately 7-14 days before harvest and feed only ph'ed water - stop watering 2-4 days before harvest


• cannabis is extracted with solvents, oils or fats

• turf's rule of thumb is capture 3 samples of pests and test treatments on them for most effective one

hermi's are caused by genetics and environmental stress....whilst rh IS an environmental stress, I would think rh might be more prone to causing susceptibility to molds rather than going hermi muA

Great Post Medi- I don't know if I am exactly in agreement with you on ONE thing though. When it comes to temperatures, the strain of the plant does come into play. Just something to consider, and as a rule of thumb, as the post does say, you are generally correct in my opinion. I had two plants show considerable growth during our hot weather here (90-100f), and they were kinda lethargic when it was in the "ideal" range. Just sayin', and no offense intended. Good day all.

Muhahaha.... yep, ya right Eek...some...many cannabis plants can will and do do well @ the higher temps...in equatorial regions in heat in excess of 38*C some cannabis plants have been clocked growing several inches a day...and if you get the medium and nute and moisture conditioned JUST right, the growth indoors can be significant...my summers here regularly exceed 40*C for days @ a time...and as long as ya keep the rootball with a good temp range, plants can not only survive, but thrive! :D hehehe

Rules of thumb are exactly th@ ...so there will always be exceptions and reinforcements to and of em .

Discussing em is one of the things I encourage... hehehe it's how we learn and pass on knowledge...and pick up mistakes { Mmmmm croooow YUM! Hysterical}
Ya point is valid...and correct :) hehehehe....

If anyone has any rules of thumb, please feel free to throw em up! :D hehehe...I will add em to the first post if they good [with appropriate credit of course! :) ] :D hehehe hey, and when ain't a rule of thumb good, eh? :lol:
