    QUESTIONS & ANSWERS

    Ask a Question
    • What type of food safe plastic is the humidity dome made of? Thank you

      The humidity domes is made of out #3 PVC.  Same type that is used in drinking water pipes.

    • I was wondering exactly what food safe plastic the humidity dome is made out of. (Recycle number) thank you

      The humidity domes is made of out #3 PVC.  Same type that is used in drinking water pipes.

    • Will this lid fit on your extra strength propagation trays?

      Yes.  These humidity domes will fit all of our seed starting trays including our 1020 flat propagation trays.

    • Please help. This is urgent. I have these but can I use with a grow light? I’m worried it will melt them?

      You can use them with grow lights.  I wouldn't recommend putting them on the domes unless they are LED and you have some spacing to avoid direct contact.   You just need to be conscious of the heat your grow lights are giving off as incandescent lights can get very hot.   We generally don’t recommend any incandescent grow lights because of the amount heat thats produced and they have a much higher cost of operation.

    • Hello! Are the 1020 Humidity Domes BPA Free? Thank you : )

      Yes they are

    • What is the diameter of the vents?

      The diameter of the entire vent is 2 3/8".

    • Do either of these fit your 32-cell reusable plant starter trays with inserts? (the 2.5" cells + insert + a boostrap farmer 1020 tray)

      The humidity domes fit snuggly on the 1020 trays. When used with the cell trays and inserts, it will lightly rest on top.

    • How do these stack for storage? Do they nest?

      Yes the humidity domes will nest inside one another for storage. Be sure they are dry before stacking and store out of direct sunlight.

    • I’m interested in getting one set of trays for growing microgreens. Is there any way to get 1 dome lid, one 1020 Tray, one Shallow Extra Strength Seed Tray with Holes, and one 1020 extra strength no hole tray. Is there a way to get one set like this?

      Currently we only sell singles of the domes however we do have some 2 - pack bundles that come with most of the items you are asking for.  Once we get more shallow no hole trays in stock we should be making more of these bundles.

    Fit well on 1020 deep trays with 6-cell packs, but wish it also sealed onto shallow trays and deep trays filled with 3.3” pots

    Super happy--only wish I had bought more!

    I am super impressed with the extra strength humidity domes from Bootstrap. I have a set of trays/cells from another brand but that brand does not make a single humidity dome to fit the whole tray. I needed something that could work as one unit, and these humidity domes were just the ticket! They are super sturdy and I can tell will last forever. I'll definitely be ordering more in the future! Shipping was super fast too! 10/10!
