It may be more pricey. But I would check out some reptile stores online. The stuff for plants I find sometimes has sand or plastic in it. I even found one to have small pieces of glass. I still order the plant type because of price but I would not take a chance if being used in a classroom.
@ohiobruce if you're not going with straight coco coir I personally recommend not using Pro mix for propagation. I don't know if you can purchase Gary's best mineral soil but that's what we've had the best luck with this year, and last year. I mix it with perlite#3, and coco coir, if you can't get Gary's best then mix with regular peat moss. LOL trust, and believe I'm not the only one who's getting better results not using Pro mix. Though I'm sure there will be opinions voiced that are not in agreement.
I’ll take the bait - why is ProMix not recommended for use? I’ve only used it one season when purchased on clearance without issue rooting cuttings, seed starting and uppotting. It’s only peat moss, coir and perlite of varying percentages.@ohiobruce if you're not going with straight coco coir I personally recommend not using Pro mix for propagation.

I was wondering the same thing. I have never used it. But it seems most fig growers love it.I’ll take the bait - why is ProMix not recommended for use?

In my area, the garden centers have closed shop for the year so I'll need to order what I need. I was planning on using coco coir and pearlite. And maybe adding peat to the mix.
But, I also bought 3 gallons of pumice, and I have about that amount of pearlite, and a 4 cu ft bag of peat moss. I also have Dip-n-Grow and a bag of OptiSorb DE I bought from O'Reilly's Auto Parts. And Mosquito Bits. And a bag of Mykos mycorrhizae. And a pH kit. And water soluble fertilizer.
If I can't get Gary's, what ratio of coir, peat, and pearlite do you recommend?
I might make 3 different mixes and try 25 of each. I've expanded my original number to account for cutting failures.
All of the students might not get a fig, but they'll get a life lesson instead. Lol.
ProMix is designed for sprouting seeds and is very fine and dense. It technically holds too much water for cuttings because of that reason. It’s about 80% peat and 20% perlite, give or take depending on the one you buy. When you read of people having to weigh their pots or use syringes for watering because otherwise they die, this is why.I’ll take the bait - why is ProMix not recommended for use?

I may have missed some of this...you are planning a class project, how many students?
If you could get a little Horticultural pumice in the mix so much the better. As been noted previously Horticultural pumice, and perlite aerate at different levels in the soil due to different weights. Roughly 30% perlite 35% peat moss, 30% coco. But if you can get ahold of Gary's best it also has 5% biochar and 10% or more Horticultural pumice. If not just go with the figures mentioned above. The reason I do not recommend promix is because there is a counter indicated Myco Strain in the mix that produces yellow mushrooms throughout the Fig pop bags. Whenever these little buggers develop we call them the yellow mushrooms of death. Cuts our success rate way back. I haven't just used it once or twice I've used it lots, and lots of times. Now I prefer to Omit this ingredient just go with peat moss. Or Gary's or any good mineral soil formula.
Thanks. Does it matter what the 50 percent is as long as there is 50 percent pearlite/pumice, etc? So, could I go 25 percent coir/25 percent peat/40 percent pearlite/10 percent pumice?ProMix is designed for sprouting seeds and is very fine and dense.

Cuttings need a more aerated mix. When it’s balanced, you don’t have to be as afraid to water them because a balanced mix is what works for the intention. 50/50 is recommended for cuttings.

You absolutely could do that!
In many ways it does not matter, even the 50/50 ratio can be altered in different directions depending on your climate. For example, humid areas may prefer a more aerated mix, dry areas may prefer a more water retentive mix.
The only thing to keep in mind is that coco coir holds less water than peat. Chunkier coco coir will hold less water than fine coco coir. Some things provide both aeration and moisture retention, such as vermiculite.
Not to make it more complicated for you! But you really can play around with it a lot.
Some make gritty mixes where they combine a bunch of different things, like coarse clay particles, zeolite, sand, vermiculite, DE, pumice, perlite, etc. and then add in a certain percentage of peat to help keep moisture dispersed throughout the mix.
Well then, such a great idea deserves some assistance, if you pm me your address I will send you 4 bricks of coir to start you on your journey.61. I originally intended to do less than half of that and hold a raffle for the trees, but after seeing their interest, I figured I should try and give one to everyone. Go big or go home, right? Lol. So now I'm rooting a few in my basement to see if I can get it figured out before next spring.

If you would like them that is.
np at all, I used to use it a lot, but switched to Promix, and since it comes in such large bags...I never opened the coir. lolThat would be great. Thank you!
