Individual Piece Measurements
Each Seed Starter Kit requires approximately 20 cups of potting soil.


Ok- the idea of these is great! Compact, aesthetically pleasing, easy to move to garden for transplant, etc. BUT here are my cons…
1. The slits make them dry out too quickly. I decided to line with coffee filters to help with multiple issues and this kept them a bit more moist. 1 star off for this
2. I don’t know How the heck people are getting their seedlings out but these are impossible to remove and not destroy. With the coffee filters I ended up letting them dry a bit and pushing from the bottom. Now- I have tiny baby hands so this worked for me but my fingers would stick so this probably wouldn’t work for others. These are too small at the base I’d say.
3. What about heating mats?!? With 2 layers under the starters heating mats seem impossible. I ended up taking the solid base away and finally my soil got to where it needed to be.
I would not recommend and wish I would have returned honestly.
I love the razzleberry color and the trays! I don't use the domes for the most part.... I bought quite a few when they came out but I barely use them, originally you did not have to buy the domes with the trays. I would buy more but I don't want any more domes!
I have the green and black seed starter kits and I'm so glad I have a burst of sunshine on the dismal March/April days when I start seeds indoors. I started growing cauliflower and kale and the domes help keep the humidity so seeds sprout quicker and grow strong!
My first time using I am starting beans and they are currently almost ready for planting. I really like the center handle for carrying.
This is my second seed starter kit. I love the first one and got great results that I decided to order another in a different color.
