Are these as strong as the epic 6 cell inserts that Kevin espiritu sells ? I want to buy a product that will last a lifetime. How long will the bootstrap 6 cells last in years?
We expect ours to last a lifetime under normal usage conditions. Ours do have a little more flex. However from our testing we expect these to last just as long if not longer. The additional flex increase the impact resistance giving it better resistance to impacts.
Does this contain 60 of the 6 cell tray?
Yes, a 60 pack contains 60 of our 6 cell insert trays.
Doesn’t the soil just fall out the bottom with the larger opening?
Some soil might fall out when you first fill the cell tray with a dry mix. If you fill them with a premoistened soil mix, you'll have much less fall out.
What’s the white stuff on top?
It is vermiculite.
Would I need to pot up still with these before planting outside? I see you have the individual/traditional pots, but they don’t have the air prune slits or open hole in the bottom. Doesn’t that negate the goal of the seedling air pruning? Thanks so much — new home gardener here. :)
The need to up pot would be dependent on what plants you are growing. We have a number of resources here that may help you. https://www.bootstrapfarmer.com/blogs/how-to-grow-seedlings
Which 1020 tray (without holes) do you recommend with these? I can’t tell if the shallow or deeper ones are best
