Smart gardens — countertop hydroponic systems like AeroGarden, Click & Grow, Lettuce Grow, and Gardyn — are marketed as the easiest way to grow fresh herbs and greens indoors. Pet owners have a specific question that most marketing copy conveniently skips: are the plants you grow in these systems safe for your cats and dogs?

The answer is nuanced. The systems themselves are not toxic. The plants you grow in them may or may not be. This guide breaks it down clearly.

The Core Rule: Safety Is About What You Grow, Not the Device

AeroGarden, Click & Grow, Lettuce Grow, and Gardyn are hydroponic growing platforms. The plastic pods, grow lights, and water systems are not toxic to pets. The only pet safety question is: what are you growing in them?

Always verify every plant you intend to grow against the ASPCA Toxic and Non-Toxic Plants database. If your pet eats any plant and you are unsure: ASPCA Poison Control (888) 426-4435.

Pet-Safe Plants You Can Grow in Smart Gardens

The good news: many common culinary herbs are non-toxic to cats and dogs. The following are ASPCA confirmed non-toxic and commonly available in pod form for smart garden systems:

• Basil (Ocimum basilicum) — ASPCA non-toxic to cats and dogs
• Dill (Anethum graveolens) — non-toxic
• Cilantro (Coriandrum sativum) — non-toxic
• Parsley — non-toxic in small amounts (large quantities may cause photosensitization; normal nibbling is fine)
• Lettuce, kale, and most leafy greens — non-toxic
• Mint — note: most culinary mint is listed by the ASPCA as toxic to cats and dogs when consumed in large quantities. Small incidental exposures are usually fine, but this is not a plant to grow within easy pet reach.

Herbs That Are Toxic to Pets — Avoid in Smart Gardens with Pet Access

These commonly grown herbs are ASPCA toxic and should not be grown in a system your pet can access:

• Chives (Allium schoenoprasum) — ASPCA toxic to cats and dogs; causes hemolytic anemia
• Garlic — highly toxic to both cats and dogs; never grow within pet reach
• Tarragon — ASPCA toxic
• Mint (most varieties) — ASPCA toxic to cats and dogs; keep out of reach

Always verify your specific pods against the ASPCA database before setting up near a pet’s reachable area.

AeroGarden — Pet Safety Assessment

AeroGarden systems come with various pod kits: Gourmet Herbs (includes chives — avoid), Salad Greens (generally safe), Tomato (non-toxic fruit, non-toxic plant), and Flowers (verify each flower species individually).

AeroGarden pet-safe strategy: Use salad green pods or stick to basil, dill, and cilantro. Skip the Gourmet Herb mix (it contains chives). Keep the unit on a countertop out of pet reach — AeroGarden lights extend the unit height and most cats cannot comfortably access a standard counter without jumping.

Click & Grow — Pet Safety Assessment

Click & Grow (Smart Garden 3 and Smart Garden 9 Pro) focuses heavily on herbs and edible plants. Their pod catalog is extensive and clearly labeled. The platform has better pod variety control than AeroGarden — you can select exactly which herbs you grow rather than buying a mixed kit.

Click & Grow pet-safe strategy: Browse their pod shop and select only ASPCA-verified non-toxic herbs: basil, dill, cilantro, lettuce, and kale all work well. Avoid mint and chive pods.

Lettuce Grow Farmstand — Pet Safety Assessment

Lettuce Grow’s Farmstand is a larger, tiered hydroponic tower designed primarily for greens, herbs, and vegetables — not just a countertop appliance. It is also significantly more expensive and takes up more floor space.

Pet consideration: Because the Farmstand sits on the floor or on a low stand, pet access is easier than with countertop systems. If you grow any toxic herbs in a floor-standing unit, your pets may reach them. Stick to greens, lettuce, and ASPCA-verified herbs. The Farmstand’s primary strength is volume — you can grow a lot of greens at once, all of which are non-toxic.

Gardyn Studio 2 — Pet Safety Assessment

Gardyn is a tall, tower-style smart garden designed to sit on the floor. It grows up to 30 plants simultaneously in a vertical column. The height (around 5 feet) means the upper pods are generally out of cat reach — but lower pods are accessible.

Pet consideration: The AI-managed app makes it easy to swap out pod types. If you have cats or dogs with floor access, configure lower pods exclusively with non-toxic greens and herbs (basil, lettuce, kale), and reserve upper pods for anything else.

What About Cat Grass in Smart Gardens?

Cat grass (wheatgrass, oat grass, barley grass) is ASPCA non-toxic and genuinely good for cats — it supports digestion and gives them a safe plant to chew, which may reduce attention on your other plants. Most smart garden systems can grow cat grass with the right pods or seeds. See our best cat grass kits review for dedicated cat grass solutions.

The Bottom Line

AeroGarden, Click & Grow, Lettuce Grow, and Gardyn are all safe for households with pets — if you control what you grow in them. Stick to basil, dill, cilantro, lettuce, and greens. Avoid chives, garlic, and mint (large quantities). Keep floor-standing systems away from areas where pets can access the lower pods unsupervised.

Frequently Asked Questions

Is AeroGarden safe for cats?

The device itself is safe. The plants you grow determine pet safety. Stick to basil, lettuce, and dill pods — avoid Gourmet Herb kits that include chives or garlic. Keep the unit on a counter or surface your cat cannot easily access while plants are small and accessible.

Can I grow catnip in a smart garden?

Yes — catnip (Nepeta cataria) is ASPCA non-toxic to cats and dogs. Growing it in a smart garden works well, though be prepared for your cat to be very interested in the unit while catnip is growing. Some Click & Grow pod options include catnip.

Are tomatoes safe to grow in a smart garden with pets?

The ripe tomato fruit is non-toxic to pets. The leaves and stems of the tomato plant, however, are ASPCA toxic. If you grow tomatoes in a smart garden, ensure pets cannot access the leaves and stems during the growing process.

What is the safest smart garden for a home with cats?

Countertop systems (AeroGarden Harvest, Click & Grow Smart Garden 3 or 9) are safer for cat households because they sit on a counter at height and have smaller, more controlled plant selections. Floor-standing systems (Lettuce Grow, Gardyn) put more pod area within pet reach and require more careful plant selection for lower positions.
