- In this episode of SoiLab, we test different potting soils found at big box stores! We planted and monitored the growth of lettuce, peas, and tomatoes, along with soil testing, to see which mix tested best and produced the healthiest and most robust plants. Watch to discover the surprising results and get expert tips on choosing the best soil for your garden!
Hello there, just found this channel a couple of weeks ago. Tests backed by science...perfect!
I really want to see something like this for lawns for peat moss (mix) vs manure vs topsoil bags vs native soil
Awesome data I got beat on the kellogs but I have the data to make it right
I just picked up a huge bag of Miracle grow organic today, so I'm feeling much better about my choice. Thank you for this information.
You are very welcome! Thank you for watching!
So as a grower i have some critiques
They all got the same amount of water every day
But not all soils retain moisture at the same rate!
a soil with peat and vermiculite will need less water then a soil with coconut coir and perlite
I think it would be a far better representation if you had moisture meters and tailored the watering to keep them all at optimal moisture level. Over or under watering will certainly skew the results
Thank you for this I always wonder which one to pick
Kellogg's seems to be a consistently worse product. Here you can see that it looks like a high concentration of shredded wood that hasn't been broken down enough, and is probably robbing even more nitrogen from the plants than the other ones, although they all probably have this issue to some degree. Would have been interesting to see stuff from pro horticulture, and fox farm. In addition it would have been good to do at least one fertilizer application across all boxes, as I believe miracle gro soils usually have some fertilizer added
I appreciate the feedback! We've got Fox Farm and several others in the lab now and will be publishing the results soon....stay tuned!
i love videos like this.
Your channel is my go to channel for soil education. That said, I have a question about the Miracle Gro products. I've noticed that depending on which state you live in, the ingredients vary greatly. Will my results vary? (I'm in California.)
We’re glad you’re enjoying the channel and content; we love helping educate! Bagged soils may vary in different states for many reasons ranging from manufacturing and storage to legislation, so your results may vary. That being said, we have seen similar trends with these same brands in previous studies. If you are using the soil to “top off” a garden bed and incorporating with existing soil, this can certainly change the composition and nutrient levels within the entire rooting profile vs using the mix as a stand-alone soil. This is why we always recommend a soil test before planting so that you can amend your soil with the products that your fertilizer philosophy aligns with to grow the healthiest plants.
@@SoiLab If I use the product, it will be as a winter mulch. I've "embraced" no-till, biochar and alfalfa pellets. Naturally I should have my soil tested, but right now I use the earthworm activity and tomato plant explosion for feedback. (All is well.)
For years youtubers have been detailing their abysmal results using Kellogg, not realizing that the fertilizer is seriously lacking in those OMRI listed products. I wouldn't pay more than $3 per bag for any of them.
Where's the Fox Farm? Where's the Espoma? Kellogg is the absolute WORST and miracle grow is okay for house plants. Food grown in it tastes weird.
Fox Farm is great, haven't tried Epsoma, is it pretty good?
@@dudemcgee256 no. Never had any good results using espoma not to mention all the gnats
@@TerpyTen Good to know, thanks!
Agree with your question. What a waste to test soil bought at a big box store. Go test fox farm, Fort Vee, and others based on a more regenerative and biologic mindset vs. the chemical approach of most of those tested.
The regular Miracle grow has added synthetic Nitrogen, kinda cheating.
It's not cheating, it's just not an organic form
