Cultiv8 Tube Heater Heat Bars – Energy Efficient Heater for Greenhouses & Grow Tents

Cultiv8 Tube Heater Heat Bars are designed to provide reliable, energy-efficient heat for greenhouses, grow tents, propagation areas and indoor growing environments. Built to deliver consistent warmth while keeping energy consumption low, these heat bars help growers maintain a stable growing climate, especially during colder months, overnight temperature drops or early-stage plant propagation.

Whether you are growing seedlings, cuttings, herbs, vegetables or ornamental plants, Cultiv8 Tube Heater Heat Bars help create a more controlled environment by supporting steady ambient warmth around the root zone and growing space. This makes them an ideal heating solution for hobby growers, indoor gardeners and greenhouse users who need dependable heat without excessive power usage.

Key Benefits

Efficient Heat Output with Low Energy Consumption

Cultiv8 Tube Heater Heat Bars are engineered to provide a practical balance between strong heat performance and reduced energy use. Instead of relying on large, high-powered heaters that may overheat small grow spaces, these tube heaters offer a gentle and consistent heat source suitable for enclosed or semi-enclosed growing areas.

This makes them especially useful in grow tents, small greenhouses, propagation chambers and indoor garden setups where temperature stability is important.

Ideal for Greenhouses and Grow Tents

Temperature fluctuations can slow plant growth, stress seedlings and reduce overall plant performance. Cultiv8 Tube Heater Heat Bars help maintain a warmer, more stable growing environment, making them suitable for use in:

  • Greenhouses

  • Grow tents

  • Propagation areas

  • Seedling zones

  • Indoor gardens

  • Hydroponic setups

  • Small plant rooms

  • Cold corners or low-temperature growing spaces

By helping reduce cold spots, these heat bars support healthier plant development and more consistent growing conditions.

Versatile Wall or Floor Installation

Cultiv8 Tube Heater Heat Bars are designed for flexible installation. They can be secured to a wall or positioned along the floor, allowing growers to choose the best placement for their growing setup.

Wall mounting helps save floor space and keeps the unit neatly positioned, while floor installation can be useful for adding gentle warmth from below or along the base of a grow area. This flexibility makes the heater easy to integrate into different grow tent and greenhouse layouts.

Better Temperature Control with a Thermostat

For more accurate heat management, Cultiv8 Tube Heater Heat Bars can be paired with the Cultiv8 Heat Mat Thermostat. Using a thermostat allows growers to monitor and control temperature more precisely, helping prevent overheating and unnecessary energy use.

This is particularly helpful for propagation, seedlings and sensitive plants that require a stable temperature range for healthy growth.

Durable and Low-Maintenance Design

Built with a robust exterior, Cultiv8 Tube Heater Heat Bars are made for long-term use in demanding growing environments. The durable construction makes them easy to maintain and suitable for repeated use across different growing cycles.

Their simple design means less hassle, easier cleaning and dependable performance when consistent heat is needed.

Supports Healthier Plant Growth

Cold growing conditions can slow root activity, reduce nutrient uptake and affect overall plant development. By adding a steady heat source to the growing environment, Cultiv8 Tube Heater Heat Bars help support:

  • Stronger early growth

  • More stable propagation conditions

  • Improved comfort for seedlings and cuttings

  • Reduced cold stress

  • Better environmental control in winter

  • More consistent greenhouse and grow tent temperatures

This makes them a valuable accessory for growers who want to improve plant health and maintain productivity during cooler periods.

bag came ripped so the chewy pig ears were not chewy they were hard, I didnt even give them to my dog. The worst part is they are not returnable or refundable - what a waste of money So not acceptable.

Awesome quality balls -- my dog loves them!
Color: F) 3-Pack (2.5" Balls)
Love this 3 ball set and variety and quality. These are the 2.5" size, similar to a tennis ball size give or take. The fun citron yellow one is the thickest + heaviest, very bouncy, and tough. The blue is still tough but not as thick or bouncy, a bit more flexible. And the clearish one is the lightest/flexible and is glow in the dark [although we haven't tried that part yet]. I have a 7month old 40lb girl who is becoming like a power chewer on some things -- but hasn't done that with these. She can play, mouth them, chew them, not even one knick or anything. Yes! The citron and blue one we leave out all the time in her little toy box. They have holes in the middle and have used them to hold thinner bully sticks and other treats. The blue one is fun to put smaller treats inside that she can work out like a puzzle. Obviously they are fun for fetch! We leave the other up and only get out when we can play with her because label said it is not a chew toy so we didn't want to take chances. Overall super fun and cool and good quality, human and dog approved LoL. ***We ordered the 2 set of 4" balls, blue and purple [they are same consistency of the blue ball] and love these too! Very fun and good at using with treats the sticks too, plus these don't get lost under sofas and furniture like the smaller ones, a big plus.

Glow and play - pups favorite!
Color: A) 2-Pack (2.5" Balls)
I can't say enough good things about this glowing fetch ball! It's perfect for outdoor play at night—my dog loves chasing it in the dark, and the bright glow keeps the fun going even after sunset. What really impresses me is the quality; this ball has withstood my pup's enthusiastic chewing (and believe me, he can demolish a regular ball in seconds). It’s durable and built to last, making it a fantastic investment for any dog owner. If you're looking for a fun nighttime activity, this glowing fetch ball is a must-have!

My Dogs Favorite for throwing
Color: D) 2-Pack Lattice (3.25" Balls), Color: D) 2-Pack Lattice (3.25" Balls)
We brought our new adoptee home end of July, and I quickly had to find him replacements for his tennis balls because those balls are inherently abrasive and our yard has sand which gets in the fuzz and makes them extra abrasive and they were already causing tooth wear (our previous shepherd chewed tennis balls like gum for a week after his adoption, wore his teeth tips enough I noticed and I took them from him too but this guy didn't like the hand me down replacement, it was too big for his preference so I had to hunt down different ones for the current dog). I tried the glow in the dark Chuk It ones, but he doesn't like to carry them, or the smaller regular chukits... My current dog prefers these web style ones. I like glow in the dark stuff and it makes them easier to find in the evening or over night (if you have night adjusted eyes and not a lot of lights in the yard these are VERY glowy at night). Now I know he likes them I am thinking winter is coming and I may lose the glow color in the Michigan snow, so I'm here to order some in some in non snow camouflage because I want to be able to play in the winter without as much groping for hiding balls (literally he will chase and then snub any other balls in the yard I throw except the huge jolly ball but that isn't a fetch type ball, its a thrash toy. these are the only ones he will actually return for me to swap and throw indefinitely). I included video and a picture of them at the local beach. They float with enough above the water for maybe a few ants to use them as a flotation device, but take a bit of time to come to the surface when they splash down. I think brighter colors will help make them easier to find in the water as well as the snow. I think my dog likes them because the webbing design makes it easier to grip, even when slobbery his teeth can get a hold in the gaps (so can fingers haha) without slipping too badly. They also compress almost flat and boing back into shape and seem to be durable over at least 6 weeks of summer living in the yard, so far so good. They don't have a huge amount of mass so they don't whip super far but if you get a technique down you can get very reasonable distance on throws. He doesn't gnaw on them, so I can't speak to resistance to actual shearing attempts with teeth, just grab and chomp for fun, then holding in his mouth. My dog weighs about 68 lbs (we are trying to gain a bit), he is a German Shepherd, and this size fits him well (can't remember which size I got but usually Amazon shows what size the reviewer got near the title of the review. They're big enough I'm not worried he will accidentally swallow or choke on them, small enough his mouth fits them comfortably, his grip is secure because of the gaps, and he loves them. I suggest get two at least unless your pooch is super good about dropping it and letting you pick it up. With two, I can whip a ball, find the one he just dropped, and by the time he is back, I have the other one in hand. He knows I won't throw it unless he drops the one he just returned (I will wait for him to remember this), and this makes it way easier to play thow and bring it almost back (he often drops it at speed when he is nearly back to me so it rolls past me) without playing chase me for the toy... and makes reinforcing Drop It as an safe thing to do, like he isn't going to lose out if he drops the fun ball in his mouth, I have the second ball to mark (say YES!!! when he drops it) and immediately reward by throwing the ball I already had... he loves them enough that he thinks other balls are stupid so I don't want to throw a less cool ball to exchange for the cool ones haha Anyway hope this was helpful, Im off to order some of these balls in brighter colors for lake and snow visibility.
