Durban Poison DWC ScrOG

WEEK 6 VEGETATION See VEG Week 2 for details of stock solution A & B. I use the Bluelab Combo Meter to measure pH, ppm (TDS) 500 scale, and temperature. This week started with a move from the 5 gallon bucket, to a bigger reservoir. I DIY'd a tote, to use as a 12 gallon reservoir. I run this DWC on the second floor of my home, and wanted a simple, LEAK PROOF design. It utilizes a Bucket-top 6 inch net-cup. This allows me to start my girl in a 3.5 gallon bucket, and graduate from there, to a 5 gallon, and finally to the 12 gallon tote....easy transplanting. A fine tooth jigsaw blade cuts the net cup hole easily. A step drill bit works great for the access hole, as it cuts cleanly and doesn't drift. Existing holes were used for the airlines. A heavy Duty garbage bag keeps light out. I fill the system with 3 batches X 4 gallons of nutrient/R.O. water mixture. My mix/fill bucket contains an aquarium power-head that both mixes and adds oxygen to the water through the venturi effect. A spigot on the side of the bucket is used to drain it, through a short length of hose into the reservoir. To empty the reservoir, I use a small transfer pump. The pump runs on two AA batteries, and moves about 2.8 gallons per minute. This pump gets inserted into the access hole and transfers to a five gallon bucket. Monday - 2 pm. New 12 Gallon Reservoir fill up. 3 X (4 Gallons of reverse osmosis water + 8 mL Green Planet Plant Guard + 8 mL GHE CALiMAGic + 32 mL Stock solution Part A + 32 mL stock solution Part B) = 600 ppm, pH 5.8, 67F. The plant is 10 inches tall and 27 inches from the light. Defoliated the lower fan leaves that were once hanging over the edge of the bucket,.... but are now laying on top of the tote. Tuesday - 6 pm. Reservoir level down 1/2 inch. The reservoir measured 580 ppm, 6.3 pH, 70F. I then used 10 drops of my pH down to bring pH to 5.8. Wednesday - 8 pm. The plant is 12 inches tall and 25 inches from the light. Seeing some tip burn from nutrients. The reservoir is down ~2 Gallons. 2 Gallon R.O. top up. The reservoir now measures 500 ppm. I pH'd to 5.9 @ 69F. Defoliated some lower fan leaves and small branches. Thursday - 2 pm. The reservoir measured 490 ppm, 6.2 pH, 70F. I then pH'd back down to 5.8 pH. Thursday - 10 pm. The reservoir measured 480 ppm, 6.0 pH, 73F. Friday - 2 pm. Air temp 72F, RH57%. The plant is 13 inches tall and 24 inches from the light. The reservoir measured 470 ppm, 6.2 pH, 71F. pH'd back down to 5.8 pH. Reservoir level down~1.5 Gallons from full. Topped the plant above the 7th node. I was aiming for the 6th node😂 I couldn't see through this bush of a plant, lol. That'll due for now - Noticed a hollow main stem (trunk). Saturday - 4 pm. The reservoir measured 460 ppm, 6.3 pH, 68F. pH'd back down to 5.8. The reservoir is now down 2.5 Gallons from full. Peeked in at the roots - looking white and healthy, developing nicely. Sunday 5 pm - The plant is now 14 inches tall - raised light 1 inch, to 24 inches from the plant. The reservoir measured 440 ppm, 6.4 pH, 69F. The reservoir now contains about 8.5 gallons of nutrient/water solution. Reservoir change out. 3 X (4 Gallons of reverse osmosis water + 8 mL Green Planet Plant Guard + 8 mL GHE CALiMAGic + 28 mL Stock solution Part A + 28 mL stock solution Part B) = 550 ppm, pH 5.8, 67F, 12 Gallons. Defoliated some lower leaves. WOW, good growth this week! Still dialing in her feed strength. I burnt her tips a little. Hard to tell she's been topped or defoliated at all😝. I'm thinking another two weeks of veg (8 total) to get this girl to fully fill and cover this 2x4 footprint. After one round of fill, and reservoir change out, I am pleased with my DWC set up and method. Only another 12 or so rounds to go!!!! Please follow along, drop a like, comment, or question, and share your experience with this strain. Peace, DeaneR😎
