Growing cubes - peat vs. coir

16 years ago

This is my first time using coir cubes as a starter media. Anyone have any experience with it? I started some pepper seed this past Sunday in it and so far I'm impressed with it. The coir cubes I bought expanded much more than peat, such that one cube could be used to fill two 3oz. solo bathroom cups. I just snapped these pictures tonight, this is day five, if this was peat and this moist by now it would be growing mold on the surface...the coir appears much coarser so I guess it ventilates much better...only time will tell.

    I used the coir last spring, and I was impressed. I experimented by planting some in peat an some in coir. The coir seed sprouted first, grew faster, and made the strongest plants.

    That's what I like to hear John, a positive endorsement ;-)

    Looks like it will be cheaper too...and seems to hold water yet be well aerated.

    I've never heard of them. Where do you get them? I've got mold on some of my peat cubes. YUCK!

    Yes Tom, where do you get the coir ? also, what do you use the baby-shampoo and the Epsom Salt and the peroxide for ? Give us your secrets please ! thanx, sally

    This is where I got them, but it's too soon to say this is a two thumbs up....

    There's no secret with the other stuff, the peroxide is mostly for cuts and blood on clothes when I'm working outside. The baby shampoo is part of my whitefly spray when they show up and Epsom's gets added to water and given to the peppers when they are a little stressed or start dropping buds.

    Wish I had checked this before I ordered a bunch of peat pods. Ah well. Starting tomatoes this weekend, so help me.

    Hi
    I have been very impressed with it not only as a seed starter but as a terrestrial orchid media . My aroids and gingers seem to like it also. Have you noted ythat unlike peat the pH is neutral .?? Don't know how long that will last but peat always starts at below 6 and gets worse with age. gary

    In the spring Lowes had the coir blocks by Burpee available.
    Don't know if they will have them again or not. I loved them.
    Cost was about $2.50 per package of 2 blocks. I could fill 5 flats of 50 or 72 with each package ( so cost was about 1 cent per seed). I bought 5 at that time and am down to my last one. Sure hope they have them again.

    This is all good news to me. Day seven, slightly drying out and still no mold :-)

    Tom Sounds like you like it better than a seed-starting mix.... please can you tell us what your white-fly spray is, do you add the shampoo as a sticker-spreader ? I'm looking for a good effective whitefly spray and would love something that is not lethal to the good bugs and us...... thanks, sally

    Sally, it's a general purpose spray, a tablespoon each of baby shampoo, canola oil and baking soda to a gallon of water in a garden sprayer, has to be applied every 2-3 days for at least three applications when whitefly does show up and results are variable but at least its not very phytotoxic to pepper leaves.

    Thanks for the post Tom. I'm behind on my seed-starting (actually, I'm right on time for me, which is two to three weeks after I should have started.)
    But I went out and got coir this week.
