The Lettuce Grow Farmstand is the highest-yield home hydroponic system in the consumer market. The 24-plant model produces 4 to 5 pounds of leafy greens per month from a 2 sqft floor footprint, paying for itself within 18 to 24 months for households that eat $80+/month in fresh greens. This guide covers sizing (12, 18, 24, or 36 plant slots), the mandatory LED Glow Rings for indoor use, the seedling subscription program, and the real-world cost over 3 years compared to grocery-store organic greens.
Quick Answer: Which Size Farmstand?
For a household of 2 adults eating 4 to 6 salads per week, the Farmstand 24 ($800 + $250 LED Glow Rings = $1,050) is the right size. For 1 person or herb-only growers, the Farmstand 12 ($400 + $125 lights) is sufficient. For families of 4+, step up to the Farmstand 36 ($1,200 + $375 lights). The 18-plant size is the awkward middle ground — most users prefer 12 or 24. Don’t buy any Farmstand without LED Glow Rings if you’ll grow indoors — natural light alone won’t produce sustained harvest volume.
What Makes the Farmstand Different
The Farmstand is a vertical hydroponic tower that holds 12, 18, 24, or 36 plants in a self-contained 24-inch diameter water reservoir at the base. Water with nutrients pumps from the base up to the top, then trickles down through plant pockets via gravity, returning to the base in a continuous loop.
Three differences from countertop pod systems (AeroGarden, Click and Grow):
- Volume: 4-5 lbs of greens per month from a 24-plant Farmstand vs 8-12 oz/month from a 6-pod AeroGarden
- Vertical footprint: 2 sqft floor space, 4-6 ft tall — fits in apartment corners where horizontal counter systems don’t
- Subscription model: Lettuce Grow ships pre-seeded transplants monthly ($60-90/month), eliminating the germination phase
The flip side: higher initial cost ($800-$1,200 vs $150 for AeroGarden), more space, more water (4 gallons vs 1 gallon), more daily attention.

Indoor vs Outdoor Use
The Farmstand was originally designed for outdoor patios with full sun. Indoor use requires the LED Glow Rings — a separate $250 add-on (12-plant), $375 (24-plant), or $500 (36-plant) light kit that wraps around the tower providing 100W of full-spectrum LED.
Without LED Glow Rings indoors, plants grow leggy and pale. Even bright south-facing windows provide only 40 to 60 percent of the PPFD that leafy greens need for compact, dense growth.
For outdoor use (zones 7+, frost-free seasons, 6+ hours direct sun): no LED needed. Just plant seedlings, fill reservoir, plug in pump.
For year-round indoor use: LED Glow Rings are mandatory. Budget the $250-$500 into your initial purchase.
Sizing by Capacity
| Model | Plant Slots | Footprint | Height | Water | Price | + LED | Yield (Greens) |
|---|---|---|---|---|---|---|---|
| Farmstand 12 | 12 | 24″ diameter | 3′ | 2 gal | $400 | +$250 | ~2 lbs/month |
| Farmstand 18 | 18 | 24″ diameter | 4′ | 3 gal | $600 | +$310 | ~3 lbs/month |
| Farmstand 24 | 24 | 24″ diameter | 5′ | 4 gal | $800 | +$375 | ~4-5 lbs/month |
| Farmstand 36 | 36 | 24″ diameter | 6′ | 5 gal | $1,200 | +$500 | ~6-7 lbs/month |
The 24-plant size is the sweet spot for most households. 12 is too small to make a meaningful dent in salad budget; 36 is more capacity than most households use before plants over-mature.
The Seedling Subscription
Lettuce Grow ships pre-seeded transplants monthly. You pick from a rotating menu of lettuce, kale, herbs, leafy greens, edible flowers, and specialty crops. Plants arrive at 3-week-old transplant stage, ready to drop into the Farmstand’s plant slots.
Subscription cost: $60-90/month for 12-24 transplants depending on variety and season. The first month is included with the Farmstand purchase.
The subscription is the convenience killer feature. You skip the germination phase entirely (most expensive part of hydroponics in time and equipment). The downside: you’re locked into Lettuce Grow’s seedling pricing — about $4-5 per transplant vs $0.50 if you start from seed yourself.
You can cancel the subscription and grow from seed using the Farmstand’s plant baskets ($25 add-on). Most committed growers do this after 3-6 months.
What Grows Well in the Farmstand
| Plant | Time to Harvest | Yield Per Slot | Notes |
|---|---|---|---|
| Loose-leaf lettuce | 3-4 weeks from transplant | 0.5-1 lb cut-and-come | Best Farmstand crop overall |
| Butterhead lettuce | 4-5 weeks | 0.4-0.6 lb head | Lower yield, premium texture |
| Kale, collards, chard | 4-6 weeks | 0.5-1 lb continuous | Strong producer |
| Arugula, spinach, mustard | 3-4 weeks | 0.3-0.5 lb | Fast cycle, multiple replants |
| Basil, parsley, dill, cilantro | 3-4 weeks | Continuous | 3-6 month harvest period |
| Strawberries | 10-14 weeks | 0.5-1 lb fruit/slot | OK with LED Glow Rings only |
| Cherry tomatoes | 10-14 weeks | 1-3 lbs/slot | Train down or up; works with LEDs |
| Peppers (small) | 14-18 weeks | 0.5-1 lb/slot | Slow producer; only with LEDs |
| Cucumbers, zucchini | — | — | Don’t try, too sprawling |
Setup Reality
Out-of-box setup is 2 to 3 hours for first-time users. Steps:
- Assemble the tower from stacked sections (24-plant has 4 sections plus base)
- Install pump in base reservoir
- If using LED Glow Rings, mount the rings to tower
- Fill reservoir with 4 gallons of water
- Add starter pH balancer and nutrients
- Drop transplants into plant slots
- Plug in pump and lights
- Set timer (16 hours light, 8 dark for indoor; ambient for outdoor)
The unit is heavy (50 lbs assembled with water) — set up in its final location before filling.
Maintenance
Daily: Visual check (5 seconds — is the pump running, are plants healthy).
Weekly: Top off reservoir with 0.5-1 gallon depending on plant maturity and ambient temperature. Check pH (target 5.8-6.2). Check EC/PPM (target 800-1200).
Every 4 weeks: Drain reservoir completely, scrub with diluted vinegar, refill fresh. This prevents biofilm buildup.
Every 8-12 weeks: Replace plants that have over-matured. Cut-and-come-again lettuce gives 3 cuttings before needing replacement.

Compare to grocery store organic greens at $80/month: 3-year grocery cost is $2,880. The Farmstand pays back at the 24-30 month mark for households that actually eat the volume — and the per-pound greens cost drops to $1.50-2.50 vs $5-7 retail.
Common Issues
Pump failure. The pump is rated 12-18 months. Replacement is $35 and 5-minute job. Lettuce Grow sends new pumps under warranty during the first year.
Algae in reservoir. Light leaks past the dark base cause algae over 4-8 weeks. Cover any unused plant slots with the included plugs. Black foam tape around any visible cracks.
Roots clogging the pump. By month 3-4, mature lettuce roots can extend 12+ inches. Trim with scissors. Keep root mass clear of pump intake.
Plants outgrowing slots. Some lettuce varieties get bushy and crowd neighbors. Plant variety chart on Lettuce Grow’s app shows max diameter per plant — space accordingly.
Cold weather slowdown indoor. Plants slow growth below 65°F. Most apartments are fine; basements may need supplemental heat in winter.
Honest Pros and Cons
Pros: Highest-yield home hydroponic system. 2 sqft floor footprint. Subscription model removes germination friction. Outdoor or indoor capable. Excellent for serious salad-eating households.
Cons: High initial cost ($800-$1,650 with LEDs). Requires regular maintenance (5-10 minutes daily, 30 minutes weekly). LED Glow Rings add 50 percent to indoor cost. Subscription model is convenient but expensive long-term. Tower height (5-6 feet) requires high ceilings.

Is the Lettuce Grow Farmstand worth it?
Yes for households eating $80+/month in fresh leafy greens. The 24-plant Farmstand pays back in 24-30 months at $1.50-2.50 per pound vs $5-7 retail organic greens. Skip if you eat fewer than 4 salads per week or want a low-maintenance setup.
What size Lettuce Grow Farmstand should I buy?
Farmstand 12 ($400) for one person or herb-only. Farmstand 24 ($800) for 2 adults eating 4-6 salads/week (most popular size). Farmstand 36 ($1,200) for families of 4+. Skip the 18-plant size — most users prefer 12 or 24.
Do I need LED Glow Rings for the Farmstand indoors?
Yes, for sustained year-round harvests. Without them, plants grow leggy and pale even in bright windows. Outdoor use in zones 7+ with 6+ hours sun does not need LEDs. The LED Glow Rings cost $250-500 depending on Farmstand size and are essentially mandatory for indoor.
How much does the Lettuce Grow seedling subscription cost?
$60-90 per month for 12-24 transplants depending on Farmstand size and variety selection. First month is included with the Farmstand purchase. Subscription is cancelable anytime; many committed growers cancel after 3-6 months and grow from seed using $25 plant baskets.
How much electricity does a Farmstand use?
Pump alone: 8-12 watts continuous, $10-15/year. With LED Glow Rings (100W on 16-hour timer): $50-70/year additional. Total electricity for an indoor 24-plant Farmstand: $60-85/year at average US rates.
Can the Farmstand grow tomatoes and peppers?
Yes with LED Glow Rings (indoor) or full sun (outdoor). Cherry tomatoes produce 1-3 lbs per slot over 4-6 months. Small peppers produce 0.5-1 lb per slot but need 14-18 weeks. Full-size beefsteak tomatoes don’t work — too sprawling.
