I’m in the planning stages of building out a new grow. I’m planning to run 2 sealed flower rooms and a veg room.
I’ve calculated the load and I’m at approx. 165 amps for the following:
30 Gavita pro’s, only 15 on at a time
3 Gavita pro’s, for veg on 18hr
2 quest 225’s, only 1 on at a time
20 wall fan, all on 24/7
4 36k btu mini splits, only 2 on at a time
5 10" inline fans, only 2 on 24/7, rest is to purge the sealed rooms few times a day, mainly at lights off.
couple pumps on timers, only on for a few minutes, a few times a day for feedings.
I’ve crunch the numbers and I’m at an over estimate load of 165amps. When I say over estimate the items like the inline fans, pumps are calculated as on 24/7 and items like the a/c and dehumidifiers are calculated at drawing full power which we all know the amp drawn on these items fluctuate by how hard they are working.
Anyways, that 165amps do not include items like my fridge, oven, laundry etc. I also don’t know if some of the bigger items like the a/c will have a surge in power when they initially start up. Also even though I’m running these rooms on a flip, when one room isn’t using the A/C for example I’m sure its still drawing some power, even though its not running.
I’ve read some journals with similar setups, actually some with a few more lights, all running off 200amps with no issues. Am I really over estimating my figures here… should I be concerned running the above setup off a 200 amp panel or am I good to go? I’m about 2 months away from starting this project. I’m meeting with an electrician next month whom probably can answer these questions for me but wanted to get feedback from the forums… thank you!
