Gave me the knowledge and confidence I needed to plant and care for vegetable seeds.

Despite watching many of James’s YouTube videos, I still had gaps in my knowledge—things like proper watering, the ideal temperature for each seed variety, and the right way to harden off seedlings. This course filled those gaps, helping me avoid common pitfalls and setting me up for success. The short video segments and quizzes made learning both engaging and easy to follow.

What a fantastic value! I've already planted my lettuce and will be starting tomatoes, peppers, marigolds, and peas next. I highly recommend this course for first-time gardeners or anyone new to growing from seed!

Seed Starting Success! Zone 6a.

The course was great! So informative. Many of my worries were addressed including, watering, when to plant in a larger pot, hardening off and so much more! I’m in Zone 6a, so I started Lettuce on March 2nd. March 15th I will start Peas, Tomatoes, Marigold & Peppers! I’m much more confident in a successful season. Good luck all!

Great advice for seedlings!

Peppers, eggplants, and some others planted 2 weeks ago.

Tomatoes and basil were planted 5 days ago on 3/2. I only added the grow lights and heat mats on 3/2 and I already see a huge difference in sprouting and growth. Things are popping up like crazy.

Great advice as always from JP. Happy growing everyone! 😃

Phenomenal help!

This is my 3rd year of gardening and it has been quite the learning curve thus far. After finding JP's channel last month and watching so many of his YouTube videos, I finally decided to purchase everything I needed from Team Grow to start from seeds next year. I also took his recommendation on getting the Square Foot Gardening book. I bought the 21-day challenge after my purchase when I received an email talking about it, to help really nail down a successful 2026 season. I have to say that I am blown away by how great this course was! The attention to detail and streamline approach was great! I found the questions at the end of each video really helped with gaining valuable knowledge as well. The videos are short but pack a lot of great information into each one. If you are looking to start your backyard garden, this course is a MUST DO!!

Thank You So Much!

I feel smarter when it comes to growing my own food now after going through this course. I had tried planting seeds but they all died before taking this course. So I will be starting over with better understanding this growing season. Which i had a 21 day Team Grow seed Challenge certificate that i can hang in my garden.

Just what I needed!

I enjoyed the lessons very much. Although I had my seed trays all set up and ready to plant, I was feeling a little lost in getting started. These lessons were just what I needed to get me on track. I also learned better ways of handling issues like seed thinning and separating. Thank you for providing these to-the-point and informative lessons!

Do I use your surround product or the kaolin clay product for my fruit trees? What is the difference

Zone 7 and I have apples, peaches, plums, cherry, nectarine, apricot, and pear trees.

Team Grow

Hi Grower! Our Surround is a kaolin clay product, so if you’re using surround, you’re already using kaolin clay. 😊 You can use it on all your fruit trees in Zone 7! Apply a full, even coating and reapply after heavy rain for best results.

You asked what we thought your next giveaway should be. I say maybe some of your secret fertilizer or something like that! Also how can I see some updates on your 10 acre food forest.

Team Grow

Hi Grower! That sounds like a fantastic giveaway! 🌱 We’ll definitely share updates on the 10 acre food forest soon. We’re still dealing with a lot of snow in our area, but James has a video up on what to grow this month if you want to check it out! 😊

Can we rewatch the videos as often as we want after purchasing?
