So I have an 3x3x6 grow tent was wondering what would be the essentials needed when I grab a VIVOSUN 400HPS to ensure it doesn’t get over heated and have high humidity.. I was going to put 4 plants and all of them in 2 gallon pot ..

Has anybody noticed that specific brands or types of HPS bulbs put out less heat than others? I'm running the following in a 3' x 3' x 6.5' tent (Exact measurements are: 39" x 39" x 79") with a 315 CFM exhaust fan and passive intake. I'm just using the mesh intake vent at the bottom of the...

My 600W HPS ballast was unplugged just enough when moving around some things creating a 3 1/2 hour delay. I have three almost finished flowering but I also have three that I have had in flowering for a week. Two of which have just shown their first flowers. All are feminized. Will this 8 1/2...

Hello all, This is my first post after many informative learning sessions. This is my first grow, I'm running 600w mh/hps in a 31"x 31"x 71" tent. Been up and running beautifully for a week and when I went to check on my baby girls about 2 hours after lights on and....the lights WEREN'T on but...

Hey Now! I am setting up a tent and am using a 600w HPS for flowering. Cant locate the ballast for it (it will turn up or I"ll replace it). I have an old ballast for a 400w HPS - would that ballast work for this light or does it have to be specific to the 600w light? Also, could I just run...

I have 1 600w Galaxyhydro led and 1 300w Galaxyhydro led and I'm switching to flowering and I'm wondering which would be better for a faster bigger yield. I have a 600w HPS light and a 4x4x6 grow tent

I have purchased the Sun System Harvest Pro Remote Ballast an the Sun System Yield Master- 6" Air Cooled Reflector. I'll be using a 600 Watt Plantamax HPS Bulb. I'm trying to not void the warranty and am completely new to this. Is there anything you think I should know? Plugs, voltage, safety...

Hello there I ran into a little problem, so doing a little research I've learned my 4x4x4 tent might be a little too small for my 600w mh/hps setup height wise. With about 2Ft to grow if I use 3 gallon smart pots, would 5-6 plants in individual scrog nets be using this space to its potential or...

So I've been looking into getting a new 1000watt bulb and I've noticed I can get them from $25 to $125. But they all have around if not the same lumens listed in spec. So what is the diffrence between these bulbs? Do I need a $125 one or will the $60 one work just as well? Thanks for any input.
