Component List

Cactus voltage: 26 AWG wire inserted into the chlorenchyma (layer with chloroplasts & photosynthetic activity site) of the light-facing stem side

Cactus current: 26 AWG wire with 2 ohm resistance connected to the cactus voltage wire

Cactus ground: 26 AWG wire inserted into the chlorenchyma (layer with chloroplasts & photosynthetic activity site) of the shaded stem side

pH: Atlas Scientific Mini Lab Grade pH probe attached to the EZO pH circuit inserted into the Isolated Carrier Board. The pH probes are embedded into each side of the stem's chlorenchyma
