Autoflower Bruce Banner DWC

Germinating 2 seeds to get 1 viable plant. Put the seeds in wet paper towel for 24 hours which did not soften the shells. So, I used a sandpaper to scarify the shells on the surfaces and edges. Also, soft-cracked the shell at one edge to aid the embryo to get humidity. Edit 1 - The last lot was dud. I had to put 2 more seeds and got one viable plant. Planted it in Coco Jiffy. The initial smell from the jiffy post watering was a little moldy, so watered the seedling in the coco jiffy using 1:50 peroxide solution. The smell is gone, and the seedling looks happy. The roots are yet to stabilize. Once I see roots popping out of the jiffy, I will be placing them in my 20L DIY Deep Water Culture bucket. Fingers crossed. Edit 2 - Started the DWC hydroponics chamber today. 1. Placed the jiffy on hydrotons. 12 L/H air pump moving air to two 1’’ airstones 2. Following nutes added to water - TA Tripart Grow - 0.5 ml/L, Micro - 0.2 ml/L, Bloom - 0.2 ml/L 3. Other chemicals added to water - 1 ml/L Hydrogen Peroxide (6% w/v), 1ml/L of PH down as the water near my place is hard and PH 7. Measurements: 1. PH - Used drops to measure on colour scale. Current PH hovering around 6.0 2. PPM - 596 3. Temperature - 27 C. I know its a little high. In absence of a chiller, I am sure the peroxide will handle the microbes
