Make sure you have a Wet/Dry Vac on hand, There will be floods especially if you go the hydro route. There will be a day where you are filling a res and decide you need to run to the store, and forget about your res filling, then upon your return you find the basement with 3 inches of water and you res is now quite full. You will then bust out the wet/dry vac and begin clean up. Make sure all extension cords are already tied up off the ground since you dont want too be fighting electrical while wading in you new basement pond.
After this install float valves everywhere you need water filling and swear you will never do it again.....YEAH RIGHT ha it happened again
I always like to keep rockwool plugs, jiffy pots, or Rapid rooters in my stock room since you never know when you are going to need to clip a clone or 2. As well as
clonex clone gel and solutions.
Razor blades, scissors, and Hemp twine are also used quite often in my rooms.
I also feel it good to get away as well. You need a place away from all your plants where you can gather your thoughts, come up with new Ideas and just kick back turn the vape on, roll up a blunt, or rip the bong which ever you prefer.
