Indoor Seed Starting Greenhouse

It's been a looong time since I posted here but I thought this might be something worth your time to read. Background: We have an off grid tiny home in northern Michigan I spend the summer at that I put a greenhouse at. I've been transplanting my crops 45 days ahead of last frost and getting bumper crops each year. Keeps the animals out too. Our year round home is a condo so any crop growing needs to happen indoors.

So, I needed to start this years seeds and looking at the germination temps for various seeds, I thought I'd need something better than a starting tray and a mat and wanted to do a better job of starting them than last year's utter failure. Enter the home made spare bedroom greenhouse. I've started my peppers, tomatoes, cucumbers and broccoli with great success. Best part is this can be expanded to as many shelving units as you want.

1. I took one of my many spare plastic storage shelves (4 level snap together) and used shrink film window plastic with the 2 sided tape, wrapped the shelving in the plastic all the way around. Didn't shrink it, left it sorta loose.

2. Grabbed a small space heater, some PVC tubing from an old water heater exhaust, hooked it to the the PVC with a vent for each level of shelf. Keeps the greenhouse at 80-90 degrees.

3. Mounted LED grow lights on the bottoms of the shelves.

4. Put the heat mats on one level for higher temp. germination seeds. Easy to keep the soil nice and warm.

5. The plastic on the front facing side can be just pulled away from the tape and restuck when done.

6. I'm using a cordless garden sprayer for watering. Man, that works great!

Next winter, I'm expanding to 4 shelving units and cutting the center of one shelf so I have 36 inch high growth space for growing veggies next winter.

Brilliant set up! I really like the cordless sprayer idea. I did not know these existed.
