Plants IRL

Tl;DR

Coming back to the real world.

Intro

A solar panel and some microcontrollers was cool

Its time to do something more around it.

How about plants?

Because spring has come: you can notice that in the amount of weddings happening as well.

If you ever buy a flat with south orientation (northern hemisphere)

In theory: you can grow tomatoes easily.

Lets see that in practice.

Water Timing Sun

You’ve nailed the “Big Three” (Water, Timing, Sun), but there are a few more “silent” factors that can make the difference between a plant that just survives and one that actually thrives—especially for those Tomatoes and Mints.

Here are the other major factors:

1. Temperature (The “Invisible” Wall)

In Poland, this is the most important factor for your Tomatoes.

• The Rule: If the temperature drops below $10\text{°C}$, tomatoes stop growing completely. If it hits $0\text{°C}$, they turn to mush.
• The Soil Heat: Even if the air is warm, the soil needs to be warm for the roots to work. This is why we wait until mid-May in Poland to put them in the ground.

2. Air Flow (The “Breath” of the Plant)

If you grow plants too close together, the air can’t move.

• Why it matters: Wet, still air leads to fungus (like powdery mildew on your mint) or blight on your tomatoes.
• The Fix: Don’t be afraid to thin out your seedlings. If 20 tomatoes sprout in one tiny pot, pick the strongest 2 and remove the rest so they have room to “breathe.”

3. Food (Nutrients/Soil Quality)

Plants are like us—they can’t live on water alone.

• Tomatoes: These are “heavy feeders.” They need a lot of Calcium and Potassium to grow big fruit. Once they start flowering, you’ll want to give them some tomato fertilizer (look for Nawóz do pomidorów).
• Mints & Melisa: These aren’t as hungry. Good potting soil is usually enough, but they like a little “snack” of general fertilizer once a month in the summer.

4. Container Size (The “Feet” Room)

• Mints: As we discussed, they spread horizontally. Give them a wide, shallow pot so they can send out their “runners” (the roots that make new plants).
• Tomatoes: They have deep roots. They need a deep pot (at least 10–20 liters for one plant) or they will get “root-bound” and stay small.

5. Pollination (The “Birds and Bees”)

• Inside: If your tomatoes stay on a windowsill behind glass, there are no bees to shake the flowers.
• The Trick: When you see yellow flowers on your tomato plant, give the stem a gentle wiggle every morning. This mimics the wind and helps the pollen fall so the fruit can grow.

Conclusions

If tech is going to blow

I mean, if you are one of those who actually do sth with information like the software MDD

Why not trying sth in the real world?

1. After 7 days from planting the seeds, the first small green forms started to appear

I made A/B testing, ofc and place x6 buckets without plastic coverage and one with - the first seeds going out were the latter

The temperature at night dropped at ~15C and during peak I saw 35C (they are growing next to a Window glass)

FAQ

You have a great selection there! You’ve essentially bought a “Relaxation and Refreshment” starter kit.

Since you are in Poland, the timing for these is perfect as we head into spring.

Here is a breakdown of what you have and how to handle them:

1. Tomato Seeds (Pomidor)

• Polish Name: Pomidor
• The Plan: These need to be started indoors right now (March) in small pots or “multi-pots” on a sunny windowsill. They love heat and light.
• Moving Day: Do not move them outside until after May 15th (the “Ice Saints” or Zimni Ogrodnicy in Poland), as a single night of frost will kill them.

2. Lemon Balm (Melisa lekarska)

• Polish Name: Melisa lekarska
• The Vibe: This is the “calming” herb. If you have trouble sleeping or are stressed, a tea made from fresh Melisa leaves is magic.
• Growing: It is very hardy. Once it grows in your garden, it will likely come back every year (it’s a perennial). It smells like sweet lemons when you rub the leaves.

3. Peppermint (Mięta pieprzowa)

• Polish Name: Mięta pieprzowa
• The Vibe: This is the strong, “icy” mint. It has a high menthol content, making it perfect for stomach aches or a very cooling summer tea.
• Warning: Do not plant this directly in the ground unless you want your whole garden to be mint! It spreads through underground runners (roots) and is very aggressive. It’s best kept in a pot.

4. Pennyroyal (Mięta polej)

• Polish Name: Mięta polej
• The Warning: Be careful with this one! While it is a member of the mint family, it is much stronger and can be toxic if consumed in large quantities.
  • In English: It is called Pennyroyal.
  • Usage: Historically, it was used to repel insects (fleas and mosquitoes). Most modern gardeners grow it for its scent or to keep bugs away, rather than for drinking. I would stick to the Peppermint for your tea and use this one as a natural pest repellent in the garden.

A Quick Tip for Your Seeds

Since you have two types of mint and melisa (which all look similar when they are tiny sprouts), make sure to label your pots immediately! It is very easy to mix them up until they grow their “true leaves.”

Would you like me to give you a step-by-step guide on how to start the tomato seeds indoors today?

Since you’ve just planted your seeds, the watering strategy changes as they grow. Right now, your main goal is to keep the soil moist without “drowning” the seeds or washing them away.

Here is the plan for your Tomatoes, Melisa, and Mints:

1. Phase One: The “Waiting for Sprouts” Stage

Until you see green peeking out of the soil, the seeds need consistent humidity.

• The Method: Use a spray bottle (mister). Pouring water from a cup can bury the seeds too deep or wash them to the corner of the pot.
• How much: Spray the surface whenever it looks light brown or dry. The soil should feel like a wrung-out sponge—moist, but not dripping.
• The Trick: Cover your pots with clear plastic wrap or a plastic bag. This creates a “mini-greenhouse” that keeps the moisture in so you don’t have to water as often. Remove it the second you see a sprout!

2. Phase Two: The Seedling Stage (Once they have leaves)

Once they are growing, they need “deeper” water to encourage roots to grow down.

• The Finger Test: Stick your fingertip into the soil (about 1 cm deep). If it feels dry, water. If it feels cold and damp, wait.
• Bottom Watering: This is the best “pro” secret. Instead of watering from the top, put your pots in a tray with 2 cm of water. Let them “drink” from the bottom for 15–30 minutes, then pour out the leftover water. This keeps the stems dry and prevents mold (especially for Tomatoes).

3. Plant-Specific Tips

• Tomatoes: They are thirsty! As they get bigger, they will need water almost every day, especially if they are in a sunny window.
• Melisa & Peppermint: These love “damp feet.” They are less forgiving than tomatoes if the soil dries out completely. If they start to wilt (droop), give them water immediately and they usually “pop” back up in an hour.
• Pennyroyal (Mięta polej): Similar to peppermint, keep it moist but make sure the pot has holes in the bottom so the water can drain.

What to avoid:

• Standing Water: Never let the pots sit in a tray of water all day. This causes “root rot,” and the plant will turn yellow and die.
• Cold Water: In Poland, tap water in March is freezing. Let your watering can sit out for an hour to reach room temperature so you don’t shock the “tropical” tomato seeds.

Would you like me to tell you how to recognize if you are overwatering them before it’s too late?

The best time to water your plants is actually in the morning.

While many people think evening is better, morning is the “gold standard” for gardening. here is why:

1. The Morning Advantage (Best Time)

• Energy for the Day: Watering between 7:00 AM and 10:00 AM gives the plants a “drink” before the sun gets hot. This helps them stay hydrated while they are busy growing during the day.
• Disease Prevention: If any water gets on the leaves, the morning sun will dry it off quickly. Fungi and molds love wet leaves in the dark, so morning watering keeps your Tomatoes and Mints healthy.

2. The Evening Option (Second Best)

If you are busy in the morning, the late afternoon or early evening is okay, but there is a catch:

• The Risk: In Poland’s cooler spring nights, if the soil and leaves stay soaking wet all night, you might see “damping off” (a fungus that kills baby seedlings) or white mold on the soil.
• The Rule: If you water at night, try to water only the soil, not the leaves.

3. Why You Should Avoid Midday

• Evaporation: If you water at 1:00 PM when the sun is hitting your windowsill or garden, most of the water will evaporate before the roots can even grab it.
• The “Magnifying Glass” Myth: While it’s rare for water droplets to actually “burn” leaves like a magnifying glass, it’s still a waste of water and can stress the plant’s temperature regulation.

Summary Table: When to Water?

A Quick Tip for Your Pots:

Since you are growing Tomatoes and Mints in pots, they dry out much faster than plants in the ground. On a very hot day in May or June, you might actually need to water them twice—once in the morning and once in the late afternoon.

Since you’ve planted a mix of vegetables and herbs, you’ll notice they have different “wake-up” times. Some are like early birds, while others take their time to emerge.

Here is the timeline of when you should see the first green sprouts (the “germination” period):

The Sprouting Timeline

Why the difference?

• Temperature is Key: Tomatoes are “tropical” at heart. If your room is warm ($21\text{–}25\text{°C}$), they might pop up in just 5 days. If the room is cool, they might take 12.
• Seed Size: Mint and Melisa seeds are like dust. Because they are so small, they don’t have much “fuel” inside, so they take a bit longer to build enough energy to push through the soil.

3 Signs to Watch For

1. The “Loop”: Before the leaf appears, you’ll see a little green “hook” or “arch” pushing through the dirt. That’s the stem breaking the surface.
2. The “Seed Leaves”: The first two leaves that appear are usually smooth and oval. These are not the real leaves! They are called cotyledons.
3. The “True Leaves”: About a week after the first sprout, you will see the “real” leaves that actually look like Mint or Tomato leaves.

A “Pro” Tip for Your Melisa and Mint:

These seeds are very small, so if you buried them deep under a thick layer of soil, they might struggle to find the light. They only need a very thin “dusting” of soil over them—barely enough to cover them.

If you don’t see anything after 21 days, it usually means the soil was either too cold or the seeds were planted too deep.
