Seed was germinated in paper towel, between 2 plates and in a zip ziploc bag. Tent was kept around 27°C. My first grow using strictly reverse osmosis water (tap water no good).
Rockwool cube soaked in 5.5ph r.o water for 24 hours, then in nutrient water (6.0ph/100ppm) for 2 hours prior to transplanting seed into rockwool cube.
Transplanted into dwc hydro bucket.. root just hitting the bottom of the basket. Reservoir ph unknown due to old ph pens, new bluelab monitor on the way.
Struggling with water temperatures this week due to hot weather.. Reservoir sitting around 22°C, trying to aim for 20°C. Should cool down this week, hoping reservoir temps drop a bit.
*Also added 24ml Hydrogen Peroxide to reservoir.
LED's approx. 450ppfd.
Reservoir temperatures back to 20°C.
LED's approx. 500ppfd - 32"
VPD - 1.3 (weeks average).
Had a slight calcium deficiency mid-week (pic.4), mixed 1/2 strength cal-mag into 1L r.o water to top up reservoir.
Topped this week (pic 4-5).. got rid of 2 giant fan leaves blocking light below and growth took off.
Topped up reservoir mid-week with 1/2 strength nutrient solution.
VPD - weeks average 1.15kpa
LED's - approx. 575ppfd @ 75%
Recovered well from topping.. waited a week to get rid of large fan leaves blocking light and growth took off.
Top up juice made to 900ppm with airstone running on/off (30/60min).
Kept ppm below 900ppm with nutrient top up juice throughout the week. Filled out quickly after removing large fan leaves.
Scrog net install next week along with trimming.
Finishing up the final stretch of the branches, had to add another scrog net to open bud sites.
Humidity running high due to high Temps outside and plant density (need to work on trimming pre-flower). Otherwise, growing good.
Defoliated large fan leaves, still a bit messy underneath as I didn't want to stress it too much. Struggling with lowering humidity from plant density (most likely).
Finishing up stretch.
Plant density making it difficult to keep ph below 50%. Problems with ppm rising drastically, flushed with r.o water, started building ppm back up to 1100 slowly.
Hung in tent at 20° - 45%rh for 7 days. (Could have done 5 or 6 days). Then weighed and put in jars. Final yield 5.5ounces.. lots of waste on bottom, must improve training/timing.
