Which type and brand of HID would you recommend? I just got three of the 4x4 tents shown in the video, maybe I should test 1000 watt HPS against 460 watt Spectrum King.

Very righteous and awesome

thanks, I'm about to have three tents with 2-4 buckets in each and one Spectrum King SK402 in each. Each light yields 450-800 grams in 4x4 flowering space, so I'm running one in each of the three tents

Thank you, the purple 600 watt LED shown was $100 on Amazon. There are tons of videos on Youtube of each lights harvest weight so you can get an idea of how much each light will yield under recommended

Thanks for noticing! They are three 20 watt T5's, I hope to make some of the growth at the bottom and middle branch out to the sides.

wow I'm only one week behind you. You look much further ahead though.
