Promix .Good Canadian brand since 1968. Good stuff.
Still, Charles Dowding grows all his seedlings in his coarse, lumpy compost, rarely sifted….
I don't use seed starting mix. I use regular potting soil and sift it. Been doing that for years. Works great.
Started mixing my own. Micro mix 10 cups coco coir, 3 cups perlite, 1 cup trifecta… Way easier on the wallet than the bagged stuff at the box stores.
I also love using Promix HP. Best seed starting mix around. I’ve tried several varieties and love that there is no sifting with Promix HP
I agree with using a seed starting mix. I have tried the sifting method and had bad results because of the "pests" in the soil! I switched back and haven't looked back!
❤❤❤
Yes sunshine mix #4 is the best especially for this and it’s what I use so thanks for mentioning it, Luke! Happy new year.
I keep reading comments/reviews where people claim thrips and fungus gnats with Pro-Mix
Pro mix gave me a bad case of gnats the first time I bought it
How can a compost be called organic when they are using comerical gardening waste that that maintenence gardeners spray round up, fungucides and pesticides on. Then take to a waste composting facility, and compost the material and call it organic? Even Dr. Earth uses this product. Fake compost!!!!!
Pro mix is way too expensive for me 😢
I love promix. I use it for everything.
pro mix is WAY Cleaner
I worked at a nursery and we used ProMix too.
Thank you for this info!!! 🎉
i use Coco Coir and i spray with Farmer’s Secret Plant Booster once week and using MIgardener seeds never fails 95%-100% germination some best root system
Best Solution for DIY:
Get a few storage totes
buy peat moss, coco coir, perlite, sand and mini pine bark nuggs
put peat in one and coco coir in the other.
Anytime you need to make seedmix, just mix up 60% coco, 30 peat and 10 perlite.
If you want potting mix just determine the best ratio for that plant of these things. Thats pretty much all the ingredients the bagged mixes contain just mix them together as needed and save money.
Add in bagged top soil (screen it) to the mix as needed for the microbiology
I'm an Attorney and I've done a few defamation cases. I love how you said, "hyperbolic." 😅 absolutely on point. Great video and channel, sir.
Avid follower!!! Ty for your content.
So True!!!
I have bought every brand of bagged and baled soilless mixes, potting mixes, seed starting mixes and all kinds of coco. I have found all of these to be infested with the parasites you mentioned. Studied them with a microscope for over ten years. I have much better success in my potted plants and starts with my yard soil and compost. Ypsilanti Mi.
The spagnum isn't classified as soil when it is in mix, however there are places where that have peat soil. That is where the spagunm comes from. They work the peat soil with a disk and then go over it with a peat harvester which is essentially a giant vacume cleaner. The peat collected by the harvester iv run through screens and a hammermill. All the larger pieces are either screended out or broken up.
One thing you didnt mention is that pro-mix is compressed. It fluffs up when you remove it from the package. You get more volume of substrate for your dollar.
Thanks for reminding me to order coco coir. Make your own starting mix. Tons of videos out therr. I think Luke has one.
Thank you
I mix a bit of leafgro with coco and perlite. Best ever. Fill trays 2/3 with mix. Put in seed and slightly cover with vermiculite. Wet down and cover. Works like a charm. Leafgro is the best stuff.
Thanks, Luke. It's nearly time to start my plants (well, about 2 months, LOL), but this gives me time to get my seed starting mix ready.
I often forgive you for the clickbait because of the content. but there has to be a better way.!!
Question: does a seed starting mix have enough nutrients for a plant to go from seed to the garden 8 weeks later? I don't usually transplant into bigger pots before going to the garden.
I added perlite to my seed starting mix. Ive tried all this. And nothing germinated. Litterally nothing. It wasn't the seeds. I just did a normal to me mix and everything germinated.
My biggest issue is damping off. I know the seed start mix is holding onto too much water. But anything ive tried to add drainage or aeration ends up with no seed germination. On hundreds of sets. I had to start over.
So soiless seed starting is the way to go? With so much advice on seed starting this is why I stick to starter plants. I want to start from seed but dont buy this or that is wrong. I used peat free back to the roots soil. Hopefully that is a good one
I hope you sell the promix this year. Last year i didnt make the best choice in the long run and i regretted not buying the promix
What works for me is using both at the same time. I start my seeds in 3 inch pots. I fill the pots with potting mix, plant the seeds on top, then cover the seeds lightly with seed starting mix. If I get gnats, I place a yellow sticky card nearby. This method prevents me from having to pot up my seedlings again later.
I make my own seed starting mix, with equal parts Worm castings and peat, but I do have to sift out the bigger peat particles. I add the vermiculite and pearlite right after that as well so that it gives the right texture and water holding properties and I also add some lime to balance the pH of the peat moss!
I use potting mix that I screen big pieces out and add perlite to. Works good for me. Have noticed the last 3 to 4 years that there is more big pieces of wood in any potting soil I buy. Even the more expensive big name ones. Thay arent as picky about it as they used to be.
I tried some coconut coir seed starting bricks and compared it to jiffy peat pellets. It seems like it's hard for me to tell when I need to water the coconut coir.
If you’re winter sowing seeds outside in plastic milk/water jugs, and plan to keep the seedlings in them until they can be planted into the garden, don’t you have to use potting mix? Wouldn’t the lack of nutrients in the seed starting mix eventually starve the seedlings? I have always used potting mix with winter sowing, and have been very successful.
Great info as always.
I always learn a lot from watching you!!!
I have a problem with fungus gnats in my compost. How should I deal with this?
I take last years potting mix from the garden, sift it and then bake it in the oven to sterilize it. I've had good luck doing this. I also add perlite to my potting mix if it seams too heavy to begin with.
Promix has no fertilizer in it that's why you need to add a tiny bit in there for your ceilings
Soil blocks with a soil blocking mix is my preference and bottom watering.
