The top clear dome also does not snap into place to offer a flush contact to help further prevent the water dripping out.
As is- it works if you have it on a surface that can withstand a bit of water, and if you revisit it's moisture levels at least every three days.
I fear taking scissors to the clear dome's edge will only make it fit even looser to the bottom.
HOWEVER, that one only has a 2-inch transparent plastic top on it - and this one has 7 inches of growing room. In addition, this has some simple but effective adjustable vents in the hood - both ends and in the top - which are useful to control the humidity level.
Since I had to go buy the pellets anyway, I got the 2-inch hothouse they came in. I started my seeds in it, and now that they're up, I've moved thed them to the Hydrofarm product, which offers increased growing space.
What you're really paying for is the Heat Mat. It's a great idea to have a consistent heat under germinating seedlings! Before it arrived, I tried a few basil seeds in a kitchen window, and one night it got cold. Bang. Poor little guys are casualties.
Now, in the Hot House with the Heat Mat, all my babies are fine, thank you! By the way - you will need a Hydrofarm MTPRTC Digital Thermostat For Heat Mats to control the heat - sold separately.
I've got them both, and they work well together. You plug the Heat Mat's electrical cord into the Thermostat, which plugs into the wall. Oh yes - the Thermostat comes with a probe you place inside the Hot House, where it can read the actual temperature your seedlings are at.
The hothouse does a great job of keeping the soil moist, so it is not necessary to water too often. The hothouse is somewhat fragile, but is sturdy enough.
The mat heats well, and does not generate 'off-odors' when heating. At night, the window greenhouse does cool. I live in Idaho, where the nighttime temperature this season has dropped into the 20s. So, the mat was not able to maintain the set temperature, but it remained within 10 degrees of the set temperature. I did try moving the hot house-mat-thermostat combo to a warmer location for one night, and the set temperature was maintained. I choose to leave the hothouse in the window greenhouse for convenience. Considering the observed germination times, the seeds were not adversely affected by the temperature fluctuation.
This product works, and is an efficient method for seed germination! I'm very happy with the purchase.
Aside from that, I have been having great success with this system!
