A simple, reliable way to raise strong seedlings at home
There’s been a bit of interest recently in starting seeds under artificial lights — so I thought I’d share my current (very simple!) setup.
The good news? You don’t need a greenhouse, fancy kit, or loads of space. A small cupboard and a few basic bits of equipment can give you excellent results — perfect for allotment growing or kitchen garden planters.
🪴 The Setup
What you’re looking at here is about as straightforward as it gets:
- A cupboard space (or any enclosed corner)
- A MaxiBright grow light with a simple reflector/shade
- A heated propagator (just for germination)
- Standard pots or seed trays
- A bit of trial-and-error positioning
That’s it — nothing complicated.
💡 How It Works
Step 1 — Germination (Warmth)
Seeds start life in the heated propagator, which gives them the warmth they need to sprout quickly and reliably.
👉 This is the only stage where heat is really important.
Step 2 — Straight Under the Light
As soon as seedlings appear, they go straight under the grow light.
This is the key step.
Without strong light, seedlings stretch, go leggy, and weaken — something we’ve all seen on a windowsill.
Under the light:
- Growth is compact
- Stems are strong
- Plants are healthier overall
Step 3 — Light Positioning
The light is hung just above the plants and can be adjusted as they grow.
Rule of thumb:
- Keep the light close, but not touching
- Raise it gradually as plants develop
🌿 What I’m Growing Here
You can see a mix of early seedlings coming through — ideal for getting a head start on the season.
This setup is perfect for things like:
- Courgettes
- Cucumbers
- Peas
- Brassicas
- Lettuce
Basically anything you’d normally start indoors.
👍 Why This Works So Well
- 🌡 Controlled warmth for germination
- 💡 Strong, consistent light (no relying on the weather!)
- 📦 Compact — fits in a cupboard
- 💷 Low cost compared to full grow systems
- 🌱 Produces sturdy, transplant-ready plants
⚙️ Easy Improvements (If You Want to Refine It)
This is a “temporary” setup, but it could easily be upgraded:
- Add a timer (12–16 hours light per day)
- Line the cupboard with reflective material (foil or white board)
- Improve height adjustment for the light
- Add a small fan for airflow (stronger stems, less mould risk)
None of these are essential — just nice extras.
🌼 Final Thoughts
For small-scale growing, this kind of setup hits a sweet spot:
simple, effective, and easy to manage.
If you’ve struggled with leggy seedlings on windowsills, this is a bit of a game changer.
It’s also a great way to extend the growing season — especially up here in Edinburgh where light can be a bit… unpredictable!
🌱 Grow It Yourself
If you’re giving this a go, start with:
- Courgettes (fast and satisfying)
- Peas (great early crop)
- Lettuce (quick wins)
And once you’ve got the hang of it, you can scale up as much (or as little) as you like.
