probably. You can put a meter on your panel to gauge how many amps your actually using on your 100 amp panel right now.

Why not upgrade to 200? Since he's already gonna be in there. As long as the wire coming into your house can support a 200 Amp service. Price difference should be negligible.

I'm not an electrician but I have done a few remodels, your logic makes since to me. Lets say you buy that 150amp panel then find yourself needing more electricity, the cost is compounded significantly. Instead oversize your box and make it capable of more amps and if you only want 150amp service for the time being, buy a 150amp breaker (instead of the 200a) problem solved. Talk to an electrician for expertise, but I wouldn't want to change a panel out twice or kick myself later for not being able to add something I wanted.
It costs less than an ARC fault breaker for the price difference. If you want to drop 200 amp service in later, just change out the main breaker to 200amps and get your new, power company approved, feed to the box. This will allow plenty of room to run new wired circuits throughout your house/grow.
Remember hot tub heaters run off electricity if they don't take gas.

Always good to have options. And if you ever go to sell the house, its definitely a selling point. 200 amp 30 space Square D sub panel is $106 on Amazon, even comes with a few breakers. 150 amp breaker is probably only $10-$20 cheaper.

is he just going to change the main breaker? you better be careful he should be putting new wire in from the meter #1 size from the existing #3 i would go 200 amp but then the pipe would need to be 2 inch unless its a romex not sure the code where you live just make sure he changes the main wires

I thought the power company was already bringing 150amp service to the domicile and his electrician was taking it to the new panel from the exterior. Depending on the price of what the power company was charging for 150 and 200 amps, I would have to think really hard about why I wouldn't want more capability for probably only a couple hundred dollars more. Want to sell, it won't hurt saying you could wire up a disco in the back yard.

If the service feed is suitable theres no reason not to get a 200 amp panel upgrade. Not sure where your located but I know lots of sparkys and have not heard of a 150 amp upgrade, they are all 200. A 150 would be fine but if your paying to have a new panel put in im assuming might as well get a 200amp and have plenty of room in the panel to add circuits.
Would I have to call the electric company and ask for 200 amp service

does the main come over head or under ground

I'm pretty sure you can only run at 80% of total, so a 100 amp you can safely draw 80, 120 from 150, 160 from 200 etc. Im no electrician but maybe inquire from electrician when he comes, wouldn't want house to burn down now do you? Best of luck.

Ive talked to a couple electricians and was told 200A and 150A cost about the same.
I was quoted $1800 from a work contact. And $2200 from some guy who came by my house to do some repairs from a storm.
This is in the Northeast where costs are spendy. So depending on where you live you are getting the Cannabi$$ effect

One thing to consider, divide the flowering area into two rooms and put them on a flip. This will greatly reduce the electrical requirement as only one flowering room is on at one time. This is how my grow is setup to run two 10kW flowering rooms and a veg room with only a 150 amp main for the whole home.

Also good because then u can exhaust one rooms heat into the other so the difference in nighttime and daytime temps isnt that large which reduces PM and stretch

A light mover can help cut down on electricity bill, one light becomes two or three by square footage. That frees up a few amps for you.
