      • How much soil and water should be used per cell for growing basil and oregano from seeds? And do you recommend opening or closing the air vents at top. These will be grown indoors on a windowsill. Many thanks.


        Any standard potting soil mix will work.  I personally use a mix of 1/3 composted soil, 1/3 vermiculite and 1/3 perlite.  Water so soil remains damp, but not wet.  I have a mister that I use 2x a day on my seedlings.  Oregano and basil - I don't use a cover, just cover the seeds with soil and keep the soil damp.

        Hope this helps!

      • I'm looking for a heavy duty propagation/seed starter kit in white maybe even only 10-12 square plugs. I use the rapid rooters but want a couple small trays and domes to do this with. I'm sick and tired of the flimsy trays most people carry and it's also harder to find these trays in white!! Also looking for quality plastic domes too? Please let me know if you have any options for me! Thanks take care Dave

        We currently don't sell any trays in white.  Our largest cell tray is 32 cells which are 2 inches square.  However we can start looking into both products.  For white trays would you just be looking for 1020 trays?  Also what size would be the cells you are looking for?  Regarding the humidity dome we do sell an extra strength dome.  However we will be sold out until about the 2nd week in May 2017.  The domes are only available via the Kits until we have more ready to go.

      Excellent product!!!

      I got the 128 cell seed starter kit. The quality of this product is 100 times better than the Jiffy ones you get at Walmart. They are so sturdy! And the humidity domes fit on the trays perfectly. The domes do cave in if you have a fat cat that decides to sit on them before you can move them to the seed starting shelf, but they pop right back out with no damage! I can see that I’ll be able to use these trays for quite a few years before I’ll have to replace them. I’ll never go back to the cheap Jiffy trays!
