See How We Solve These Problems
It’s discouraging when seedlings turn weak or leaves turn yellow. Cheap seed starters only add to the frustration, leaving you with wasted seeds and lost time.
“Not worth it if you want to grow more—better off with a bigger light. The wires are a mess, like setting up a science project.”
“Total waste. Weak light, skinny seedlings, and a ton of seeds never popped.”
“Didn’t expect it to still be this cold in Feb. A sudden drop in temperature overnight turned all the seedlings yellow.”
“Feels dangerous—AC plug and no temp protection. Can’t believe this passed certification.”
“If it melts just sitting in the box, how am I supposed to trust it for growing? Big letdown.”
“The lights don’t spread evenly. You end up with a mix of leggy sprouts and barely-there seedlings.”

Why Does The SS-Pro Grow Faster?
2x Faster Growth
"Most seed starters heat up slowly and lack proper lighting, causing delayed germination."
LetPot's 24W full-spectrum light and 24W high-power heated base provide strong light and fast warmth, so seedlings sprout healthy leaves in just 5–7 days.
Up to 99% Germination rate
"Most seed starters average only 80%. "
The LetPot app automatically adjusts to each crop's optimal conditions and allows custom settings, raising germination rates to 99%—almost every seed sprouts.
100% Even Light Coverage
"Other seed starters use 10W light bars that are weak and uneven. "
LetPot's 24W full-spectrum panel delivers uniform light across the entire tray, with app-controlled auto or custom schedules to help seedlings grow stronger and healthier.
± 1℃ Precision Temp Control
"Other seed starters require extra heat mats with unstable temperatures and safety risks. "
LetPot's built-in heating system keeps temperature steady within ± 1 °C (± 2 °F), with an independent power supply and overload protection—safe and reliable even in winter.
< 1% EC Sensor Error
"Most seed starters rely on guesswork for watering and fertilizing, which often harms seedlings. "
LetPot's professional-grade EC sensor has less than 1% error and works with the app to remind you when to fertilize, making plant care easy even for beginners.

FAQs
Do I need gardening experience to use SS-Pro?
Not at all! Just plant your seeds and select the plant type in the LetPot App. The smart system automatically adjusts light, temperature, and nutrition monitoring.
How is it different from regular seed trays?
Without gardening experience, traditional trays often lead to leggy sprouts, yellow leaves, or weak roots.
SS-Pro requires no experience—it automatically sets the right conditions for your chosen seeds, with smart heating, full-spectrum light, built-in EC and temperature monitoring to help you grow strong, healthy seedlings.
What types of plants can I grow with LetPot SS-Pro?
You can start over 200+ plant varieties—from herbs and leafy greens to tomatoes, peppers, cucumbers, and flowers. The 40-cell tray works with standard seeds and common grow media like sponges, coco coir, or mixed soil.
How long does it take for seeds to sprout?
Most seeds germinate within 5–7 days with the 24W full-spectrum light and 24W heating system. Compared to cheap trays, seedlings grow faster, stronger, and more uniform.
How many seedlings can I grow at once?
The 40-cell seed tray allows you to start up to 40 seedlings at the same time. Perfect for preparing a full season’s worth of plants for your garden.
How does the smart control work?
SS-Pro combines a 24W full-spectrum grow light, 24W thermostatic heating base, and built-in EC + temperature sensors. The App uses these to create the best environment for each plant variety—so you get healthy, strong seedlings without the guesswork.
What if my seeds don’t grow?
Sometimes seeds fail due to seed quality, but SS-Pro minimizes risks by providing the perfect growing environment. And if your device has issues, it’s backed by our full warranty and dedicated customer support.
