13 best heating pad for plant starts

A heating pad for plant starts is a gardening accessory designed to provide controlled warmth to seedlings, plant cuttings, or germinating seeds.These heating mats, also known as seedling heat mats or propagation mats, are commonly used by indoor gardeners and hydroponics enthusiasts to create an optimal environment for early-stage plant growth. Here's what you should know about heating pads for plant starts:

  1. Temperature Regulation: Heating pads for plant starts are designed to maintain a consistent and gentle level of warmth, typically in the range of 70°F to 85°F (21°C to 29°C). This helps promote germination, root development, and healthy growth in young plants.

  2. Seed Germination: The controlled heat from the pad accelerates the germination process, allowing seeds to sprout faster. This is especially useful for plants that require warm soil conditions to thrive.

  3. Propagation: Gardeners often use these mats for propagating plant cuttings. The warmth encourages the development of roots on the cuttings, increasing the success rate of propagation.

  4. Uniform Heat: Heating mats are designed to provide even heat distribution across their surface. This ensures that all the plants or seedlings placed on the mat receive the same level of warmth.

  5. Energy Efficiency: Most heating pads for plant starts are energy-efficient and consume relatively low amounts of electricity. They are designed to run continuously for extended periods, which is crucial for successful germination and early growth.

  6. Durable and Waterproof: These mats are typically constructed with durable materials that are resistant to moisture and easy to clean. This makes them suitable for use in greenhouse environments or other humid conditions.

  7. Variety of Sizes: Heating mats come in various sizes to accommodate different gardening setups. You can find small mats for a few seedlings or larger mats that cover multiple trays or seedling flats.

  8. Easy to Use: Using a heating pad for plant starts is straightforward. You simply place it on a flat, stable surface and position your seed trays or containers on top of it. Plug the mat into an electrical outlet, and it will maintain the desired temperature automatically.

  9. Thermostatic Control: Some advanced models may include built-in thermostats or temperature controllers, allowing you to set and monitor the desired temperature more precisely.

  10. Season Extension: Heating mats can also be useful for extending the growing season by providing warmth to outdoor plants during early spring or late fall when temperatures are cooler.

It's important to monitor the temperature of your heating pad regularly to ensure it remains within the desired range. Different plant species may have specific temperature requirements, so it's essential to match the mat's heat output to the needs of your plants. Heating pads for plant starts are a valuable tool for indoor gardeners and hydroponics enthusiasts looking to create an optimal environment for the successful growth of young plants.

Why made by silicone

The traditional plastic seedling tray has a fatal common problem, that is, it is fragile and is a one-time product. The two factors of disposable products and non-degradable make plastic seedling trays very unenvironmentally friendly.

High quality

JOURMON seedling trays are made of high-quality silicone raw materials. We use double materials for modeling, so that our silicone seedling trays are twice as thick as ordinary seedlings. The difference in materials also prevents our seedling trays from cracking.

Reusable

The silicone seedling tray can be used repeatedly and is easy to clean, which greatly saves the cost of repeated purchases. It is also very easy to store after you use it, just clean it and wipe it dry and roll it up for storage.

User questions & answers

Question: Do i need to get a digital thermostal controller for this or does it work ok without the controller
Answer: Depends on what you're using it for. Like it says on the box, the temp of the mat is derived from the ambient heat in the room and will be 10-20 degrees warmer. If you need more control, then you will need a thermostat. The thermostat will help keep an even heat, but if your room is very hot or very cold you may need to find another solution. So, if your room is only 32 degrees, the mat may get up to 50 degrees, but you can't crank up thermostat to get above that 50 degree temperature. It will try its best to maintain the 50 degrees.
Question: This product is just the pad?i have to buy the dome apart
Answer: Comes with heat pad..insulation pad.and control box...most pellets come in a plastic tray with dome.
Question: I am in south Florida where it is 85+during the day and 78+at night, does that mean I may not need a heat mat or heat mat will go to temp needed
Answer: I don't believe the temperature on the heat mat is adjustable. Living in south Florida, I would be very surprised if you needed a heat mat for seedlings. I use it in the winter as we keep the heat at night in the 60s. 78+ should be plenty warm for seedlings.
Question: Can this be used outdoors? Will cord/plug be ok in outdoor extension cord
Answer: I don't see why not, no different the Christmas lights I imagine, you might want to use a plug protector that goes around both plugs, I would put mat on ground or bury it. https://www.amazon.com/Orange-Extension-Connector-Water-Resistant-Management/dp/B07JBSKVSR/ref=sr_1_12?crid=256JPUEPWDY2J&keywords=extension+cord+protector+waterproof&qid=1571358791&sprefix=extension+cord+protector%2Caps%2C134&sr=8-12

User questions & answers

Question: is this dual voltage (110-240?)? I need 220v
Answer: I’m not sure but I would ask the seller because they were quick to respond when I wanted to know what was in the culture.
Question: What temperature does this heat up to
Answer: Mine came with a 6 foot cord
Question: I have a temperature strip on my 1-gallon jar. Will the strip show the correct temp, once I wrap this mat around the jar? Thank you
Answer: I'm no electrician but the thing is so much smaller than I thought, it worked great for my Brewsy wine, keeping it warm....
Question: How long is the cord to plug it in? It looks very short? thks MM
Answer: I use a rubber band to secure mine. Velcro strips or gaffer's tape would also work. If you're using this to brew kombucha or a comparable drink, whatever you do, don't set the jar on the heating pad, which is what another user recommended. That's the last thing you'd want to do. Doing this offsets yeast growth and will ruin batches. The variance in temperature throughout the container will also be greater.

Question: Where is this made

User questions & answers

Question: Is this safe to place on a wood floor or plastic table
Answer: I lay it on a plastic tray. I’ve used them for 2 years with no problems. They don’t get hot enough to melt stuff. But just to be on the safe side with your wooden floor, I would put it on a tray if possible. I used the trays because once the seedling sprouts you need to be able to water the plants.the shelf has a lip to it so it keeps extra water from going all over. Good luck!
Question: Mats warm up when plugged in, but go cold when a tray is placed on them. Is anyone else having problems with this
Answer: I've had my mat for a long time and never had this problem. I find that it does take about 20 minutes for the trays to warm up, so they may feel cold when you first place them on the mat. But they do warm up. Maybe try giving them a few minutes to fully warm up. If they don't warm up within 30 minutes you might have a defective mat.
Question: Is this compatible with the vivosun thermostat
Answer: I bought the Ohuhu thermostat but Im sure the vivosun would work just fine.
Question: Is having the thermostat controller a must to have a successful germination
Answer: Giving bottom heat to seed for earlier or quicker germination is the goal here. Consistency of bottom heat provided by a controller best ensures success. Without a controller your soils may remain too warm or cool for consistent germination. It also helps the efficiency of your mat to place 1/2 construction styrofoam beneath the mat to maximize pads output. A small thermostat inserted into your soil also allows you to monitor the soils temps to best maintain the optimum soil temps for a particular seed.

User questions & answers

Question: It says a "2 pack". Are there really two 10X20.75 mats sent for the price of
Answer: Dear customer,The 2 pack contains two mats in one box !
Question: Can I regulate the temperature of this-like a heating pad
Answer: Not with out the separate special control, which Amazon sells also.
Question: Can this be used under newborn puppies or will it become too hot
Answer: Sorry, for that call the vet. I've only used light blankets, since the mother does most of the warming.
Question: Can any user confirm whether this heat mat is kept on all the time 24/7 till germination starts OR need to be unplugged after being on for some time
Answer: I keep mine on 24/7 unless Greenhouse temperatures reach 70 degrees or higher which this time of year is only for a couple of hours during a very sunny day. The mats generate heat “gently” so leaving them on constant heat has not been a problem for me. Hope this helps! They have worked very well for me.
