I have just recently gotten into plants and gardening. I have been having so much fun starting seeds and starting new plants from my larger plant clippings. These are durable and built to last. I was worried about them cracking because of the weight of the soil and plants. They are the perfect size for what I need. Not too big or small. They make the process of starting seeds a breeze. They have good drainage. I will recommend them. [INCENTIVIZED] [Received Free Product] [Originally posted on influenster.com]
Amazing quality, so strong and sturdy with great materials. I�m excited to start my garden early this year! Easy cleanup, no assembly needed, and easy maintenance. [INCENTIVIZED] [Received Free Product] [Originally posted on influenster.com]
These are great seed starter trays! The trays are super sturdy and hold plenty of soil without any fear of cracking. I was able to plant some herb seeds to get ready for spring planting. I'll definitely be able to get good use out of these trays for years to come. [INCENTIVIZED] [Received Free Product] [Originally posted on influenster.com]
What a great seed starter or planting station tray! It is a great size and not heavy at all, so it�s easy to move. It is a little less sturdy than I�d like, but overall this is a great plant accessory. [INCENTIVIZED] [Received Free Product] [Originally posted on influenster.com]
One of my trays arrived cracked in a corner, but I�m guessing it just had an extra rough trip during shipping because these are very sturdy and durable. I will get many years of use from them. They�re huge and will be amazing for starting my seeds this upcoming spring. I will need to drill holes in the bottom or get tray inserts for drainage since these are one solid piece. I wish they came with lids, but I believe those are available for purchase separately. The trays conveniently stack into each other for storage. I�m planning to use two to stagger grow sprouts for my chickens and have some chia started for them as shown in the pictures.

The strength and quality of these Viagrow seed starter supports are exceptional. I will be able to use them for many seasons to come. They are going to be so easy to wash and store away each year too. I would much rather spend my money wisely on these reusable trays. They are so much thicker than the thin disposable ones that end up in the trash after one use. After only a few uses they will pay for themselves. The grooves are the right depth to hold enough water for seed pots to absorb without drying out or becoming overwatered. It took me a few failed seed starts to realize how important bottom watering is. Now I just need to find the same quality in seed pots to go in them. Then I am done buying disposable starters for good. This is going to save me so much time and money. I highly recommend them. I do wish they came with a clear greenhouse dome and seed pot inserts, but this does give me the option to start seeds in different materials and sizes.

If you've ever bought those super cheap flimsy black trays from the garden center, you know how annoying they are�they crack if you look at them wrong and bend in the middle when full of wet soil. These trays are the complete opposite. I use them for seeds, microgreens, and wheatgrass. They're BPA-free, reusable, and built to last for years. No more spilled seedlings. Highly recommend if you want quality that lasts. [INCENTIVIZED] [Received Free Product] [Originally posted on influenster.com]
So excited to get these trays growing! Fantastic quality plastic. I�ve already started looking into other Viagrow products just to see what else they offer. [INCENTIVIZED] [Received Free Product] [Originally posted on influenster.com]
As you can imagine from the picture, I am starting cat grass in one of these trays. I was very surprised that five were sent! They�re really great quality seed trays. One is plenty for indoor off-season planting, but if I want to get herbs and garlic started, I can do that too. The material is slightly flexible but very durable and stands up well to gardening tools. They are definitely reusable and not made from the thin disposable plastic found in cheaper trays. There are no drainage holes, but there are designated areas where holes could easily be drilled if needed. Cat grass doesn�t require drainage, so that wasn�t an issue for me. I can�t wait until my fat orange cat sees this tray full of grass. He�s a furry little lawnmower and he�s about to get his dream indoor lawn.

This seed starter is very durable and stable. It will be helpful when I start planting my garden. I will be able to grow many more plants throughout the year because it is large enough and helps keep seeds from getting too much water. The shape is perfect because it does not take up too much space and can easily fit on a rack. I would recommend this seed starter for anyone looking to start a garden.

Decent size, very durable, and strong. Very beginner-friendly and easy to use when planting. Has enough room to fit up to 10 plants. Great addition to have when planting. [INCENTIVIZED] [Received Free Product] [Originally posted on influenster.com]
Exactly what you�d hope for. The tray is strong and sturdy and I was able to move it around with my basil plants in it without feeling like it would collapse inward or jiggle and drop one. [INCENTIVIZED] [Received Free Product] [Originally posted on influenster.com]
It's made of plastic and can be stacked when empty for easy storage. It is easy to clean and does exactly what it is intended to do. It comes ready for soil and plants. [INCENTIVIZED] [Received Free Product] [Originally posted on influenster.com]
