RINBO Seedling Heat Mat, Heating Mat Heated Propagator, Hydroponic Seedling Reptile Plant for Indoor Gardening Greenhouse, Durable Waterproof 100% Safe (10"x20.75")

This heat map has proved to be one of my best and most useful tools in the growing of plants and seeds. I researched loads of custom made trays for a lot more money than I paid for this heat mat. They all look good but when you read the small print they are very small unless you pay big money. I also did not want to have a big item to store not being used at warmer times of the year. The mat seemed to fit the job I wanted perfectly so thought at the price of £18 it was worth a try. I also purchased 2 x trays with clear lids from Wilko's for £4.00 each so total cost £26.00. I made the box from off cuts and put some insulating foil in the bottom but it does not get that hot to worry about underneath heat I just wanted to direct any heat upwards into the soil. I am having great results and with no loss which has not been my previous experience. Some data you might be interested in. width 255mm by length 500mm. When turned on it shows a usage of 20watts on my smart meter. Calculate that and it costs to keep on 24hrs a day 6p or 40p a week or £1.63 a month. Not expensive to run and the accurate temp gauge you can see in the photos tells me it is a constant 22deg C. I have thought about buying a plug in thermostat to control the temp but at £20 ish I thought currently not worth the investment but maybe later. Hope this helps and of course dont forget when not in use the mat folds up and the box can store pots in the green house.

This has proved to be extremely useful and beneficial for my tomato seeds. I was a little late in planting so I wanted to try to get ahead with them and boy! did this heated pad do that. The seeds germinated ultra quickly and I'm on course now for some great toms this summer. The pad is very efficient and easy to use. It simply plugs in and provides a good constant warmth without getting too hot - in other words it does exactly what you would expect. It came rolled up in a box. When it was unpacked it didn't lie flat from where it had been rolled, but I left it in the warm sun for a little while and it smoothed out most of the unevenness and then in use it flattened out further - so all good. It's big enough to accommodate a full size see tray, with a little room to spare if you had a couple of little pots of seeds that needed a bit of heat. So in summary - it's highly recommended!!

Seems to be working so far and have no complaints. Bought it to help bring a bring along some indoor bulbs that clearly the cold and lack of light were not helping. No temperature control but don't think needed as stays constant even temperature

I bought 2 of these as I live high up and we get lots 0* temp at night.they are small, I can get one full seed tray on each mat but my seeds germinated in 4/5 days even with glass plates missing from my green house so I’m very impressed. All my seeds did well and I’m using them for the seedlings now . The down side is that once the temperature is reached, it stays hot and in small modules, which is what we all use for seedlings, the compost dries out fast. You just remove the tray from the pad and water it and I turn the pads off mid morning as in this heat wave we’re having, it gets up to 30* in the green house by 3 pm.i think for the size they are vastly over priced like anything that has a ‘gardening ‘ tag on, and wonder if I put a cheap electric blanket (£24) in a waterproof bag, I could get a lot more seedlings to come through. I do have a very large garden though, so if you’ve got a small veg patch etc I. Sure a couple of these would work for you. It’s useful to cover with thick plastic covers or fleece or something over the top at night to keep them warm until they look strong enough to to transplant. Even with cosy roots, the frost can burn the tips. All in all a useful acquisition for any gardener growing from seed.

This throws out some good heat, it's cheap to run and seems pretty durable. The heat from the pad managed to get through the plastic bag, tray and into the little pellet things and pots. They were noticably warmer than everything else, i had some problems with carolina reaper seeds germinating, 3 out of the 8 i planted germinated 17 days after planting, the other 5 seemed to not want to sprout so i got this pad, the very next day id used it all 5 other seeds germinated and broke through the soil. Very happy with this purchase, im sure it will last many years. The pad itself is made of some sort of plastic material which feels very durable. It comes rolled up in a box, you can re fold it and store it easily...good luck getting the plug back in the box though!!

Simply took out the box, unrolled, plugged in and it works, within 12 hours of using this item my seeds (tomato) began to germinate, they had been planted two days before with no visible action. Some people have commented that they would prefer a temperature control but being a novice to these gardening technologies I wouldn't know what temperature to adjust to so I am grateful for the 'lack' of choice here, the uni-temperature appears to be effective, my tomato and scotch bonnet pepper seeds are responding very well to this mat, I definitely recommend. The mat is black with green writing instructions which are clear.

The heat mat works fine and gets warm as stated it should but it seems to me that it doesn’t appear to be an even heat all over and it is a lot warmer in the middle than anywhere else meaning the chilli plant seedlings I had in the middle of my propagator, were drying out much quicker and required more watering. Still not bad for the price though!

Had a while now, easy to control, works well, you do need to set it lower for temps you want in my opinion. I use it for plants and its great for a 2x2 tent with grow light in the winter for growing. In summer will need not it, but for seedlings its great, so its has a duel use for me.

Ich habe die Heizmatte jetzt seit mehr als einem Jahr in meinem Terrarium in Benutzung. Ich stelle sie allerdings nur im Winter an, damit die Temperatur drinnen einigermaßen stabil bleibt. Die Pflanzen mögen die Wärme im Wurzelraum. Super für Stecklinge und Co. Ich bin zufrieden damit

Ancora da provare ma a vederlo sembra oro.....👍🏼👍🏼🌱🌶🌱🌶

Heizmatte ohne Regler, 51 x 51 cm, 45 Watt. Hab,s für mein Growzelt bestellt damit es meine Pflanzen im Winter auch bei ausgeschalteter Beleuchtung kuschelig warm haben. 😉

tutto perfetto...grazie

I bought two mats, and I'm using them to germinate my chilli seeds. They obviously aren't perfect - what can you expect for the price, right? - but with a bit of MacGyvering, I have found them to be serviceable. Like others before me, I found that most of the heat is produced in the middle third of the mat. There's also no thermostat, but that problem can easily be overcome with a cheap mechanical timer. After experimenting a little, I found 90 minutes on/90 minutes off worked for me, but everybody will have their own needs according to ambient temp etc. I used an extension cord with its own switch, so I can see at a glance when the mats have power. By separating the mats by 2 inches or so, I have enough room for my 3 seed trays. I used the sport towels to cover them for 2 reasons. 1. to protect the soil from overheating, as the mats really do generate quite a lot of heat in the middle. 2. due to the middle section being "sealed", the temperature in that area remains fairly constant throughout the width of the tray. The trays on the outside are either rotated by 180°, or swapped with each other, 3 or 4 times a day. That way, the parts over the middle of the mats don't get all the warmth and leave the outside parts insufficiently heated. The close up pictures show the seedlings at 12 days after planting, so IMHO it seems to be working so far. I obviously can't comment on the longevity of the product, but once I'm finished with them for this year, I will be storing the mats flat to reduce the possibility of the heating elements breaking.
