This is jane at 6 1/2 weeks of 12/12. this is my second grow the first to make it this far. first one was a hermmie. Annyway I have been using shultzs 10-54-10 at half strength with 2tbl spoons of molasses per gallon of water. I water about every 3-4 days because temps stay in upper 80s durring light on time and lower seventies to upper sixties at night and thats with intake and exhaust fans. I water with water and mollasses only every two weeks or so. My test kit shows surpluss of pot ash and phosfurous with depleted nitrogen and a ph around 6.5. Alot of lower fan leaves on the main stalk and on the lower branches are yellowing completly before falling off. She is currently 55in with 19 branch sites(38 branches totall) off the main stem, not including the main cola. With all of this information in mind............ Has anyone else grown sativas out this tall? What kind of yeild am I looking at? Is 112g possible? Any input is needed. Thanks in advance.​

Figure close to 1/4 gram per watt = 250 W x 0.25 grams/w = 62 grams to a possible 250W x 0.5 gram/w = 125 grams.

Your 250 watt light will only penetrate the canopy about 8". Depending on the strain you may want to multi harvest - just clip the buds that ripen on the top of the plant and move the light down as you chop the plant lower with each harvest. I do this with a lot of strain and double the initial harvest. I just clipped 2 cups of trimmed bud from the very bottom of a Jack Flash, there was only honey oil leaf and bud before flowering longer.

With a low wattage light you need short plants, SOG, SCROG, LST.
