If you are going to grow this you need to do it right.
Ph is VERY important.
The pH scale is basically a rough guide as to how many Hydrogen ions are present in any given substance; the more hydrogen ions are present, the more acidic the substance becomes. The pH of distilled water is 7.0, this is neutral. Any solution with a pH below 7.0 (i.e. pH 1.0 to pH 6.9) is an acid and any solution with a pH above 7 (i.e. pH 7.1 to pH 14) is an alkali. The pH scale is logrithmic, that is, a pH 6.0 solution is 10 times more acidic than a pH 7.0 solution (pH 5.0 is 100x more than 7.0!).
A humidity and temperature gauge are essential in any growroom.
Daytime conditions should be 70-80 degrees without co2, 80-90 degrees with co2 until the last two weeks when daytime temps should be kept between 70-80 and co2 can be reduced to adjust for the lower metabolism. Night temperatures should be kept above 60 degrees to prevent stress. It is preferrable during flowering to have a night temperature drop of 10-20 degrees to stimulate flowering hormones and reduce stem elongation.
I find that low humidity causes stress on plants. I recommend 50-60% humidity until the final 2 weeks of flowering. At this point, the humidity should be lowered as much as possible to encourage the plant to seal and protect itself with additional resin. (I am able to get the humidity to go as low as 31%) I have been able to frost things up considerably this way. The higher humidity levels prior to final ripening reduce salt levels within the plant tissue and encourage healthy, more lush growth.

Pre-Germination Soak..
Materials:
-Glass of (ideally 7 pH) water
-Cannabis Seeds
-Superthrive or other preferred formula (Optional)
Procedure:
Place your seeds into the Glass of Water...at this time you may add a drop of Superthrive, or whatever mixture you see fit.
Leave the seeds alone for a while (1 hour to 6 hours, whatever amount of time suits you...please realize that soaking for 6 hours rather than 1 could improve germination rates.).
Soaking loosens the shells of those really stocky seeds, and helps pave the way to a strong Cannabis Plant. Generally speaking, most seeds that float are worthless; those that sink are running candidates.
Germination Technique
Materials:
-Tupperware Container
-Lightly Wetted Cloth, Paper Towel, and Napkin.
-Mild Heat Source
-Pre-Soaked Cannabis Seeds
Procedure:
Remove the Cannabis Seeds from their Glass of Water.
Place the seeds onto the Lightly Wetted Paper Towel (or whatever you decided to use. by the way...use common sense, don't try to germinate on wet cardboard.)
Place the paper towel into the Tupperware container then seal the container.
Place the Tupperware container on top of a heat source... I personally use my router, or use the top of the fridge or something else practical.
Finally, open the container once in a while and look for moderate condensation, this will relay that there is an adequate level of humidity...if everything is running smooth, you should notice "changes" within a few days to a few weeks.
When you notice the protruding taproot, it's time for soil.
