+Summary: Grow log for my home hydroponics setup, round 2.
+Wide: true
+Short: hlog2
+
+2022-03-05: Started germinating  
+2022-03-07: Just barely noticed germination  
+2022-03-08: Noticed all leaves except spinach again  
+2022-03-10: Transplanted into tote  
+2022-03-12: measured pH: 6.0  
+2022-03-20: thinned out weak plants  
+2022-03-25: lettuces have no roots below net pot. others have lots of roots in the water. some leaves have a weird film on them, some have white stuff.  
+2022-03-28: Three lettuces wool dry on top. No roots below net cup. Roots are growing a bit out the sides. Dropped wool to bottom of net cups, topped water up to 1 cm above bottom of net cup. This might harm the other plants? The lettuce roots grew through a lot of the clay balls but not enough to reach the water.  
+- I assumed the clay balls would wick up enough water that it wouldn't matter.  
+2022-03-30: EC measured 1.1. trimmed oldest leaves, lettuce roots now good in water  
+2022-04-01: pH measured 6.7. brown tips on lettuce.  
+2022-04-06: Harvested first salad, arugula and cress taste horrible like paint thinner. Lettuce was good.  
+2022-04-14: Terminated.  
+
+
+## Germination
+- index is top left in tray
+- rinsed all equipment with water
+- 1 L growth solution prepared
+	  - 1 L tap water
+	  - 1.3 mL plant food
+	  - 0.5 mL pH Down for 5.5 pH
+- forgot to shake plant food
+- 12 mineral wool cubes each soaked for 10 seconds
+- three seeds of each, except five for arugula and cress in X pattern
+- hole was opened with a broken toothpick
+- seeds tamped down the hole with the toothpick
+- remaining solution added to the bottom of the tray
+
+### Result
+(columns left to right)
+
+- iceberg lettuce LT541
+- arugula MS483
+- romaine lettuce LT470
+- cress MS495
+- butterhead lettuce LT458
+- spinach SP705
+
+
+## Growth
+- used 102 L HDX tough totes
+	  - sides bow out quite a bit, try duct taping
+- 100 L growth solution prepared
+	  - 100 L tap water (estimated)
+	  - 117 mL plant food (needs more?)
+	  - 10 mL pH down to 6.0
+- cut six holes into Foamular
+- transplanted sprouts into net cups
+- layer of clay balls under and around sides of starter plug
+- filled tote pretty much to brim
+- tote sides bowed out quite a bit. maybe it's 110-120 L full of water?
+
+### Layout:
+(reading order)
