Absolutely! Storebought wheatgrass flats are much better than the powder! I take the powder pretty often, but as you know, there is nothing like fresh juice. I love to juice a couple ounces and mix it with cold filtered water and chug it. I have a lot of fun growing it, It's easier than one would think. there are cheap kits on amazon ...like this one... and they come with seeds, good soil, trays, and azomite.
I've read that wheatgrass thrives in cooler weather. My first batch has done surprisingly well in the middle of summer (It averages around 80-85 here in West Virginia). My setup is on a table on my back porch. It is shaded almost all day until 6 pm or so. I water it once a day until the tray leaks.
The kit I purchased included trays, soil and azomite. This product is amazing. I'm used to store bought wheatgrass that is grown in a small 4" by 4" container on some kind of absorbent pad (absorbent pad = no nutrients). This soil and azomite produces some amazing stuff.
I feel great. I've been taking between 2 and 4 oz. of straight wheatgrass for the past several days, and I look and feel excellent. I am trying to clean up my diet and some other bad habits. Once I do, I think the effect of the grass will be even greater.
Here is a pretty simple vid on growing.
And this is the kit I used, and have had success with. It includes a book and detailed instructions.
Good luck! Let me know how it goes.
