What is the Dosatron Hobby Cultivator and who is it best suited for?
The Hobby Cultivator is Dosatron's entry-level nutrient delivery system, operating at up to 5 GPM and handling approximately 150-300 plants depending on emitter size. It's ideal for small caregiver license holders, basement or R&D grows, small veg rooms, or any grower automating hand-mixing who isn't ready for a full commercial system.
How does the Hobby Cultivator differ from Dosatron's commercial units?
The Hobby Cultivator is built from polyacetal rather than the polypropylene used in commercial units like the D14, giving it less chemical resistance but a much lower price point. It has one fixed injection rate rather than adjustable ranges, and it's designed as a consumable — the only serviceable part is the maintenance kit, rather than fully replaceable internal and external parts.
How long does a Hobby Cultivator unit last?
Dosatron testing indicates roughly a 3-year lifespan with proper annual maintenance kit replacement.
What's included when I buy the 4-pack?
The 4-pack includes 4 units, unions, and suction hoses. MSRP is approximately $1,500 for the pack, making it a low-barrier entry point for first-time Dosatron users. Individual injectors can also be purchased separately if you need to add capacity to an existing setup.
Do I need a monitor kit or water hammer arrestor with the Hobby Cultivator?
Not necessarily. Since recipes aren't switched often in a typical hobby setup, a simple test port for hand-testing is usually sufficient instead of a full monitor kit. A water hammer arrestor is still recommended for warranty purposes, though it's less critical here since the downstream line is usually short.
How do I set up multiple Hobby Cultivator units for a base A/B nutrient line?
For a two-part base (A and B), use one injector per part to hit the target injection rate — typically around 1:175, or roughly 20-22 mils per gallon. If you need a higher injection rate than one unit provides, two units can be plumbed with suction hoses to the same tank, splitting the draw between them.
Can the Hobby Cultivator be used with liquid or soluble/dry nutrients?
The units are designed primarily for liquid nutrient lines, but they can work with solubles — you may just need to mix the stock tank a bit heavier, or double up injectors pulling from the same solution.
