Just bought a pop up greenhouse and it’s slightly too short .

Thank you for your message ! Is this bulb ok ?

I really don't know. Hopefully @Tom will know if these are safe or the same as a spot bulb

That Flukers bulb doesn't say on the packaging how wide the beam is

Understood so you’re saying, build the base as close to the size of the greenhouse as possible ,

and build the height of the walls taller. Is 12 inches high enough ?

And cover the floor of the base with liner . Will a tarp work ?

And to place the base on some sort of platform to raise it off the ground ? I was thinking maybe 4 to 6 cylinder blocks that are 12 inches high?

Yeah so it fits nice and snug in there
Yeah 12 should be fine
A tarp could work, a mould resistant shower curtain or even some cheap pond lining
Yeah place both the base and cover on something to lift it ideally, if your temps are reading ok then don’t worry too much, was just a thought

That brand do definitely do flood bulbs because I’ve seen them on other threads, hence I’ve used them in my examples, but I think the brands labelling is tricky, I’m not sure if they actually label their floods from their spot bulbs, does it have a frosted front on the bulb? As it’s it’s not clear glass?
