Hey fellow gardeners! I’ve been testing the Garden Patch GrowBox for several months now and I gotta tell you – this little self-watering planter has some interesting quirks. Let me break down everything you need to know before buying one.
Quick Verdict
The GrowBox is great for growing veggies in small spaces, but it ain’t perfect. While it’s easy to use and works well for most plants, some users (including me!) have had issues with assembly and the flimsy cover pins.
What’s in the Box?
- 4-gallon water reservoir base
- Upper planting container
- Nutrient Patch cover with fertilizer sleeves
- Assembly instructions
- Plastic pins for securing the cover
Note You’ll need to buy potting mix and plants separately
Key Features & Specs
- Dimensions: 27″ L x 12″ W x 11″ H
- Water reservoir: 4 gallons
- Growing space: Fits up to 18 plants (depending on type)
- Colors: Standard green or designer colors (like eggplant) for $8 more
- Price: $29.95 + shipping (basic model)
The Good Stuff
1. Self-Watering System That Actually Works
The water reservoir keeps plants hydrated through a wicking system I only needed to refill it every few days, even in hot weather. My tomatoes and lettuce stayed perfectly moist without any fuss.
2. Space-Efficient Design
Perfect for:
- Apartment balconies
- Small patios
- Urban gardens
- Raised garden areas
3. No Green Thumb Required
The Nutrient Patch takes the guesswork out of fertilizing. You get:
- Pre-measured nutrients
- Weed prevention
- Moisture retention
The Not-So-Good Stuff
1. Assembly Challenges
Real talk: Getting this thing together can be frustrating. Watch out for:
- Sharp edges on plastic pins
- Difficult-to-bend flaps
- Tricky reservoir attachment
2. Cover Issues
The plastic pins that hold down the Nutrient Patch cover are:
- Too short
- Prone to breaking
- Often ineffective in wind
Pro tip: I ended up using landscape staples instead – worked much better!
3. Salt Build-up
Some users (me included) noticed white mineral deposits between the planter and reservoir. This seems worse in areas with hard water.
Growing Results: What I Planted
| Plant Type | Results | Notes |
|---|---|---|
| Lettuce | Excellent | Ready in 2 months |
| Tomatoes | Good | Needed extra support |
| Herbs | Very Good | Easy maintenance |
| Peppers | Mixed | Some blossom end rot |
Tips for Success
-
Soil Matters:
- Use ONLY potting mix (not garden soil)
- Fill halfway, water thoroughly
- Add remaining mix, water again
-
Plant Spacing:
- Don’t overcrowd
- Follow the marked spots on cover
- Consider plant size at maturity
-
Water Management:
- Keep reservoir filled
- Don’t water from top
- Monitor more frequently in hot weather
Cost Analysis
Initial Investment:
- Basic GrowBox: $29.95
- Designer color option: +$8
- Shipping: $6.95
- Replacement Nutrient Patch: $8.95 (organic: $13.95)
Optional Accessories:
- Support cage: $24.95 (not recommended – build your own instead)
- Additional Nutrient Patches for replanting
The Bottom Line
The Garden Patch GrowBox is pretty solid for growing veggies in small spaces. While it’s got some annoying assembly issues and the cover system needs work, the actual growing performance is impressive.
Who Should Buy It?
- Urban gardeners with limited space
- Beginners who want an easy start
- Anyone tired of constant watering
- Patio/balcony gardeners
Who Should Skip It?
- People needing large growing areas
- Budget-conscious gardeners
- Those who prefer traditional garden beds
My two cents: Despite its flaws, I’m keeping mine and even thinking about getting another one for next season. Just remember to grab some landscape staples for the cover, and you’ll be good to go!
