I love these things for starting seeds. They keep the soil nice and moist so I don't need to mess with spraying the top or setting the seed trays in water every night. Ones the seeds have sprouted though they will keep the soil too wet if you constantly use them. The trays need to dry out a bit. They are also great to put under plants if you are going to be gone for a week.

This is just what I expected. My only problem is one I see in a lot of plant starters. It's difficult to fill. The top looks great because tucks well into the sides. But how do you fill it? You have to either carefully pour into the edges or lift up the corner of the raised tray with the mat on it (with all your plants on top) and pour it in. I would recommend opposite diagonal corners with a cutout for pouring water into. Overall, however, It's really well made and the mat fit well and feels sturdy. It's BIG. Bigger than most starter trays..and sturdier.

I use this self-watering tray to keep plant cuttings (that I'm trying to start) watered at a steady rate. I must say that the tray works great- the reservoir holds quite a bit of water, and the cloth covering wicks the water up underneath the pots, where the plants can get it. When the cloth wears out, I just order a new one. Thank you, Gardeners Supply!

Used with seed starting. Made watering much easier.

I can fit two of these side by side, short-end to short-end on my 4' wide, 18" deep growing rack. If they were just 1/2" or so skinnier, I could fit three of them on the same rack long ends touching, with just a little overhang. They each hold about a gallon of water each, and with a heat mat under them, the water stays slightly warm, which is good, though the mat still feels cool. I grew plants in cowpots on these trays and can fit 12 of the larger cowpots (5" square, 4" deep) on them, and they can easily take the weight of plants unlike the other brands of watering seed trays which would collapse under such weight. If I leave the pots sitting for two long, the tray can get a bit of mildew, but otherwise I love these trays. They are a little pricy, but well worth the money. (And when I am not using them, the bottom tray works perfectly as a work station for my son's Lego kits).

I bought four of these to use with my tomato grow bags but the tomato bags seem too heavy for them when filled and watered. They don't seem to hold much water, considering the size of the bag. The filler holes are hard to reach if the bag is large. The grow bags do need some kind of a self-watering device; I'm not sure that this is it. I think they'd be fine for smaller grow bags or seedlings and would recommend them for that. They've not actually broken down so I am continuing

I am using my grow bags with the watering trays for growing vegetables and fruits on my patio. They have been so great. I did most of the plants as direct sow seeds and they sprouted without me having to worry about it. I check the trays every couple of days to make sure they have water and that's it. I did accidentally squirt the inner liner with a higher pressure hose and it removed some of it, but caught the error and the liner is still working.
