Find some other brandI bought this because I'm basically lazy and I wanted the advantage of self watering system. I'm now into 2 hours waiting for the little pellets to grow and expand. I finally used a pocket knife the break them up. Burpee's idea of using my fingers to tease these apart in the midst of an inch and a half of water and make a mess in my dining room is absolutely ridiculous. (Small house - no garage) these pellets are so difficult to get expanded but I understand - Burpee has always done it this way and they don't see a reason to change because they've got a good business selling these. Burpee, it's time for change. In the meantime I will throw the pellets away next time and use a seed starting mix. I don't have time to mess with Burpee's hard way of doing things.

Great Idea / Pathetic ExecutionI've been using this product for 5 years now. I've finally had it and given up. There are two big problems:
The first is with the super grow pellets. In the past 4 years, I have NEVER succeeded in having them expand, and that includes trying to rehydrate with a slow trickle of hot water. This year, after the "book method" failed, I started the process around Xmas, and it still took 3 weeks of rewetting and finally manual break up to get them into usable, granular soil format for planting.
The 2nd big problem is getting the seedlings out of the cells for planting. You can't turn the whole tray over without causing harm, so you have to squeeze / dig them out manually. It's rare not to have a lot of damaged seedlings in the process.
This year, to top it off, one entire 32 cell tray of Burpee pepper seeds failed to germinate. Tomatoes did fine before suddenly dying of just before transplanting. The only think I can think of is that the pellet medium was somehow contaminated with fungus.

The best idea everI have been using these for a couple of years now for seedlings. They save me time and worry because I know the seedlings will get water without me watching them for a couple or more days (depending on size). This year I will try them for germination using the top.

Great customer service, but lousy product.I have now opened up 4 of these kits. The first 2 had broken water trays and plant holders. Customer service was prompt and courteous and sent replacement. Both of these had broken water trays, making them unusable. Again, customer service is sending replacements. The plant holders and water trays are the cheapest, thinnest, most brittle plastic I have ever seen. This is not the quality nor the quality control that I would expect from Burpee. I am hopeful that they will upgrade this product's quality...I can't be the only unsatisfied customer regarding this particular item.

Best and easiest approach to seed startingI bought this starter kit for the first time last year. I've grown my plants from seeds for 50 years. This unit produces the least amount of work and mess that I have experienced in all that time. All of my seeds sprouted in less than a week. The self watering mat is a wonderful tool. The nicely sized cells produce plants with good root structure throughout the medium for worry free planting up. If I needed to know if it was time to add more water I just slipped my finger down into the tray to check the water level. Last year I started several different kinds of peppers, 6 different kinds of heritage tomatoes, and various other vegetables and herbs. I was pleased with every single plant.
Although I have used a grow light and heat mat for years, I got the best results ever with the addition of this growing system. No more over watering or medium drying out.
I ordered a second system this year and also refills for last year's system so that I can expand the amount and variety of seeds that I start.

Creative Idea but need adviceHello, I have used this system for 2 years now, this year being my third try at making this a success. I liked the system, and of course paid a premium for it because it is a creative solution for me. I travel allot and loved the idea that the unit could water for up to 10 days. I have a problem I read in another review in that the soil seems to stay too wet. My seedlings grow well and just about the time they reach full size, root rot sets in and all the plants die. Nothing can be done to save them. The instructions for the unit simply says to dampen the mat well, and that it can water up to 10 days. Do you offer any advice so I can avoid this disastrous situation this year? Maybe the instructions should include advice on proper watering techniques for every day as well as extended absence.

Excellent results a few years ago, but...I bought these again because the ease of using them was always nice. I had very few plants fail to grow to transplantable size and did the same old routine with them. Yeah, breaking up the pellets is needed, it was before, too. Just poke it with a pencil or similar, it isn't a huge effort.
My problem was that this year for seemingly no reason, the plants all kept dying off. They'd grow to a certain height, and as first true leaves formed the stem would sort of shrink at the bottom and then collapse. Not saveable. I tried again and adjusted the water content. No dice, same thing. Of 36 starts (mostly various hot pepper varieties and about 25% tomatoes), I got 3 viable plants which are doing good outside, and two of those looked like they wouldn't make it either. When I removed them from the trays, I spotted the problem. They were getting root rot. I don't know if the composition of the watering mat has changed or what, but they'd been pulling in too much water and neither of the things I was growing would tolerate that. I didn't change my watering source or procedure from before.
My other gripe about them was that they used to include a packet of mild fertilizer to be applied after first leaves appeared... this was mysteriously absent. Not a big deal, but it was nice to have the all-in-one thing and not go hunting around for it. Next year I'll be doing my own mix. Was a great product in the past. Sorry Burpee. (The peppers that did well were Ristra Cayenne and Jungle Parrot so no complaints on the seeds. Those have always been great quality and often last years after they should have expired). Some tomato seeds that were sown outside since there were no viable starts indoors and planted too late for our season are fruiting nicely and not too far behind the store-bought greenhouse plants.

Good ProductI have about 10 of these now and they help out a bunch if you can't monitor multiple times a day for weeks. After reading some of the reviews, let me say this. I don't use the expanding soil pucks. They are a pain. I recommend throwing them out and using seed starting mix from a bag. You can dump it on and spread by hand very quickly. You have to keep a fan on these as the soil stays constantly moist and will grow mold with no air circulation. You're buying this product for the mat that absorbs the water from the tray and through capillary action waters the plant from the bottom and this feature works well. It will last about a week between waterings. Burpee would be better off offering this product paired with a bag of seed starting mix.
