N.America or Europe? it matters when it comes to electric
you will probably need to add a dedicated line for the flower room at least. map out your breakers. find what breaker controls every outlet and light in the house. you can safely run about 1800 watts from a 20 amp breaker and about 1200 watts from a 15 amp breaker so hopefully you will have 2 circuits in/near the veg room.if you use extension cords,use heavy appliance cords -at least 14 gauge, & only as long as you need.
any 220 outlets that are not in use? dryer or electric stove?
its long but read this

You want to have a licensed electrician (or at least someone who knows what they're doing) install a couple of 220v circuits and outlets for your lights, and maybe a 120 circuit (GFCI) or two for fans,etc. That's a ton of power to be pulling and you don't want to mess around with daisychaining extension cords or whatever.

do you have 2000 watts available in your veg room & 3000 watts in your flower room? if yes the you wont need a cord. if not then you will need cords.if you don't have 5000 watts available on that floor,you will need an electrician to add a dedicated circuit or 2 to give you enough power.

what i did was run a single 8/3 wire from a 40a circuit to a sub panel with 4 20a breakers inside. now i can run 4k worth of lights an a 12,000 btu portable a/c without worrying about fire, or popping breakers. now when i move i can take it all with me. there was no modification to the house other than running 1 wire, so there'll be no repairs to make later. depending on how handy you are, the location of the breaker box, the empty spaces in the box, and how hard it'd be to pull a wire to the box, you could do it yourself. extensions cords are not advisable. they are usually smaller gauged wires that aren't designed for heavy current like you'd need, and the heavy duty cords are more expensive than it'd be to just run the heavier gauge from the box. the main thing is making sure you have an open spot or 2 in the breaker box to be able to upgrade. if you don't have the extra slots in the box or an unused 220 circuit, the cords may be the only option.

+1 for running a 220v outlet. you'll be happy you did.

I might consider doing this too, thanks
