[SpaceBuild2]How to make "plant" works?

This “plant” tool is in the SpaceBuild2
I really need this plant.
but i don’t know how to make it works…
it only says “need watering”
how to water this plant?
can anyone tell the answer? please

Use waters it. If it says that, repaste until it has a number.
It doesn’t require linking, and works with oxygen scrubbers.

I dont understand…
you mean throw the plant in the water and wait for a number??
then use oxygen scrubbers tool for what?

He means press E (use) on the plant than repaste it until you see it has a number
It DOES not require linking and works with Oxygen Scrubbers…
Also if you can’t understand this good luck trying to find out this shit…
