here are the last pics of this grow. we are at a little over 10 weeks of flower. for those interested in how this grow was conducted i just wrote a description.
there are 72 bulb positions on this light. during veg and up to the end of week 3 of flower i ran them all using 5000k light. that is 1008 watts using 14-watt bulbs. there were two lights in the room so i used 2 six-hour periods in veg. one on and one off all the time. maintained about 1200 umols ppfd for a DLI of approximately 50-52 moles per day. using one light on and one off also kept the temperature and rh more consistent
at the end of the third week of flower i switched to 66 14-watt 2700k bulbs and 6 25-watt tungsten incandescent appliance bulbs. 924 watts led and 150 watts incandescent for a total of 1074 watts.
also, i maintained about 1200 umols ppfd for a single 12-hour period for a DLI of 50-52 per day.
i used jack’s 3-2-1 ratio but at different overall strengths. all input, no solution was removed from the system during the entire grow. the first two weeks i used the 3.6-2.4-1.2 grams per gal dose.
the rest of veg up through the end of week 3 of flower, the stretch period, i used 3-2-1 grams per gallon.
the rest of the flowering period i used 2.4-1.6-.08 grams per gallon. the last 10 days ph adjusted water only.
ph was maintained at between 6.0 and 6.5 using 85% phosphoric acid.
lights on temps typically 80-84f and lights off in flower 72-75f.
no co2 was supplemented here but my co2 monitor says that i got over 400 ppm throughout the grow.
i got 6978 grams of untrimmed wet flowers from 2 plants. I like measuring the wet weight anyway so i can monitor the dry down more accurately.
these were grown in a recirculating, closed-loop, soilless system known as the PPK using 6 gals of #2 perlite as the main body of the medium amended with 3 lbs worm castings and one 18 oz solo cup full of diatomaceous earth.
to the nutrient solution, with each 30 gal load mixed, i used 30ml of mr fulvic 1ml per gallon, and a heaping teaspoon of maxicrop kelp powder per 30 gals.
i think i learned more about bulb spacing during this grow. the spacing i used here is not ideal and used an unnecessary amount of electric energy.
i’m about to move and will design more efficient arrays when i build my grow area.
that’s all, folks!

i want to add that this plant is Blue Star OG from BlueStarSeedCo. it is a cross of Blue Star and Triangle Kush.
Blue Star is a cross of Deathstar and Whitaker Blues. Death Star is a cross of ECSD and Sensi Star.
Whitaker Blues is a cross of Quimby and DJShorts F5 95 Blueberry.
Triangle Kush is of unknown background but is thought by some to be the most potent variation of OG Kush.
it is the winner of a pheno hunt i did using 50 seeds to sort through.
it is an extremely potent plant with a nice citrus fuel flavor up front and a floral perfume back. a smooth, potent, pain-relieving type of plant. it just makes you feel good!
below is a graph showing the approximate spectral distribution of a 2700k led and a tungsten incandescent.
