or i can not guess and just order a killawatt...seems like the best option since i'm going to get at least 2 more panels that will cover a 4x4 area this spring...and probably another light like an sp250 or another icky led for the main led room...
i checked the local lowe's and home despot and they don't stock killawatt meters,i kinda doubt the local grow store has them...growers house wants 35 bucks for one....seems steep since the home depot website has them for 19.95...but i need to get one...i do have 6 led lamps now...
..i still refuse to buy any sort of pH meter though!
I have 1. Keep in mind they only work on 120v devices.
I don't blame you...
I mean, who needs to meter their pHosphorus anyway?!
