Homemade Mini Hot House

Pete’s mini hot house works so well, it would be a sin not to share how easy it is to make.  It is also “dirt” cheap to create plus you are recycling (sort-of) all the while not needing to have a big garden, as this little nursery will fit perfectly on a window sill.

You will need:

  • Empty 2 litre soda bottle
  • Pebbles
  • Palm Peat or potting soil
  • Seeds of choice
  • Tray/saucer (optional) – needed if you make holes in the bottom of the bottle

Mini hot house 1

Cut the bottle in half.  I find it easiest to poke through the bottle with a craft knife making a slit big enough for the blade of a scissors to fit into.

Mini hot house 2

Poke a few drainage holes through the bottom half if you like for additional drainage.

Place a few pebbles in the bottom for drainage.

Mini hot house 3

Fill approximately three quarters with palm peat made up according to the manufacturers instructions or with potting soil.

Mini hot house 4

Sprinkle your seed over the surface of the dirt and cover with a light layer of soil.

Water and squish the lid on and place in a sunny spot.  Water once a week until seedlings are ready to be transplanted.

  1. aaah these are awesome we used to make them as kids with the 2L coke bottles that had the black plastic base to them…we’d pull that off and plant the seeds in there…cut the neck of the bottle off and turn it upside down over the seeds…works like a charm!! fun project for kids 🙂

    • Hi Janine, I remember doing that with the old coke bottles too – worked like a charm because there were already holes in the bottom of the base plus it was a nice dark environment for the seeds. Aah, the good old days. Have a happy day. 🙂 xo

  2. Hi Mandy, nice tutorial 🙂 I also use the top half of the 500ml bottles to protect seedlings planted directly in situ against weather, snails and cutworm. Laura

  3. This is great, Mandy! Anything to repurpose those plastic bottles. They’re everywhere! I need to consider using them when I start my spring planting. (Gee, that makes it sound like I’ve a farm to plant. Ha!)

    • Oh dear Bam, what a pity about your bonsai. My hubby has just started with bonsai growing. I hope it won’t be too long before you start with another tree – I’m sure your next seed would sprout perfectly in one of these mini hothouses. Have a lovely weekend. 🙂 xo

  4. Great seed starting idea! I’ll ask my students to bring me bottles since we don’t use/have them at home. I’m going to try for some celery, sprouting from celery I trimmed in the kitchen. Woo-woo-celery!

  5. Thank you so much for sharing this. I LOVE IT! I’ve just had the rest of my basil “mowed” by The Moe & this would be a great way to keep curious kitty out of my plants. Now I just have to get some new seeds – I hope they start putting those out soon here.

Don't be shy, leave a reply. :-)
