    Plastic worth using because it will last

    I’m just now beginning seed starting for this season, using the 6 cell plug tray inserts to germinate seeds and planning on using these 4 cell plug tray inserts to up-pot seedlings. I feel like the Bootstrap Farmer products are an investment in the future. We have begun replacing flimsy plastics in our community garden with these more sustainable options. Definitely will get more!

    Great company, great products. And I love the Bootstrap podcast!

    I have not yet used my 4-cell trays, but plan to use them for potting up my indoor tomato and pepper seedlings in the next week or two. I think they will work perfectly.

    Excellent for starting peppers

    Started hot and sweet pepper seeds 2 weeks ago and they have already germinated. Great for bottom watering.

    Great experience

    The tray inserts are tough and should last a long time. They will make better starting trays for the larger plants that I start. With the air pruning slots, there will be less stress when I transplant. You’ll definitely want to use them with the deeper trays. They were shipped quickly and arrived in great shape. I do like buying from this company, they listen to their customers and produce/have products that a person can feel good about investing in.

    YES!

    Have been using the smaller 6 cell version. These larger 4 cell version are what I requested, wished for, and need. Relatively heavy duty units should last many seasons. Just a home gardener. Probably will not be in need for awhile. 5 Star value. N of 47degrees. It is indoors under the grow light season. Planted my normal indoor veggies along with a few test items using these cell plugs. Larger cells should mean seed to harvest with no need to transplant to larger containers.
