• Ep 004: Jeremy says 'we use the Chapin sprayer which you'll see me using to just spray them down in here.'
• Ep 021: Jeremy mixes the rootwise/aloe/enzyme/saponaria solution in a bucket, pours it into the Chapin sprayer, and mists the freshly transplanted clones.
• Ep 028: Jeremy is mixing 3.5 gallons because that's the right volume for his chapin sprayer and easy to stir and pour. The chapin can handle humic acid chunks if you remove the nozzle.
