Continuous-spray bottle for misting kits.
A 32oz pump-pressurized spray bottle that produces a fine continuous mist rather than a coarse stream. Cheap, but the fineness of the mist matters — coarse droplets pool on the substrate cut, breeding bacteria.
Use: Stage 2 onward of beginner course; standard tool for fruiting all kits

Buy →Chlorine-free water for misting and substrate prep.
Tap water with chlorine or chloramine stresses mycelium and reduces yields. Distilled water (or RO water) eliminates the variable.
Use: Misting kits, hydrating substrate
$4
Buy →Track yields. Calibrate substrate hydration.
A precision kitchen scale lets you weigh harvests to compare flush sizes, and dial in substrate hydration by mass rather than guesswork. 0.1g resolution is the sweet spot — finer is overkill, coarser misses small spawn batches.
Use: All tiers — yield tracking, substrate prep
