Review: Worth the money - I was surprised these guns weren’t dearer because some guns that only read temp are more expensive. It seems well made too I’d definitely say they’re worth the money!! If you grow using vpd as a guide one of these guns is a must it takes all the guesswork out and the plants love the temp and humidity I’ve set it at
Review: Handy - Works great
