Which Potting Soil Is Best? Collection 1

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 would have never thought that MG would be a winner. I will have to change my ways. Thank you. Any chance doing a Neem meal and Karanja cake demo.

That's interesting and the difference is huge. As someone who just wants to start growing a few plants on the balcony I spend to much time watching videos like this.
Perhaps I should start with legumes (chickpeas?)

[MatthewRyan-kv]

No surprise seeing the soil mix having a stunted growth

[MickF]

Why is it that nearly every video on sowing seeds or growing seedlings, the products from Kellogg's being "tested" are their Raised Bed & Potting Mix and their Garden Soil? How about testing their two Potting Mix products, one for indoors and one for outdoors? I've seen pretty good results with the latter.

I really want to see something like this for lawns for peat moss (mix) vs manure vs topsoil bags vs native soil

[mysticshadow]

Thank you for this I always wonder which one to pick

[chuckbailey]

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

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.

[SusanSmith-delm]

My Miracle-Gro bags has many pieces of wood in it. Products just aren't the same as they were in the past. I'm dissapointed. I guess I have bark for my trees and plants.

[markc]

Awesome data I got beat on the kellogs but I have the data to make it right

[danmartin]

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.)

[keyphabenyisrael]

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.

[Bob-wbj]

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

[mikesmith]

U can’t compare garden soil with potting mix.

[TerpyTen]

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.

[richardsmith]

The regular Miracle grow has added synthetic Nitrogen, kinda cheating.
