hps

I'm about a week away from 12/12. My veg room has 3 lights, 2 x CFL 250w and 1 HPS 600w. Now the plants are older, every time I put one under the HPS its drooping and on one strain the leaves are actually turning around.. I'm worried as when I turn to 12/12 next week, all three bulbs will be...

I just purchased a used Lumatek 1000LK ballast on an auction website. This is the non-air cooled kind. However, every bulb I've tried to fire up has only flashed for about 1/2 a second, then no light emitting from the bulb, till around 1-3 minutes later, and another flash, repeatedly. The...

Ok im 3 weeks in from seed and im using 10 cfl's and a few LED bulbs just for vegging then im adding a 400watt hps bulb when i throw them into flowering. I know alot of you are gonna say or are thinking just add the hps right now but i dont have a overhead reflector or ballast yet. So anyway...

hey all. So I'm new to the site so please forgive me if this is in the wrong place!? I was looking for grow logs but couldn't work out how to post there? I started this log on a different site but unfortunately it has gone down the pan, it appears the grass is greener where you water it and said...

Hi all, Just trying to figure out if I'm better off buying a double ended high pressure sodium system or a single ended air cooled system. I'm torn because the double ended system produces more light for the amount of energy but doesn't work with air cooling. With the single ended air cooling...

Hi Guys, I have a few 600w MH + HPS bulbs and a few cool-tube enclosures. I've just finished my first grow using 2 x 600W MH for Veg and 2 x 600 HPS for flower, with good results. However, in all honesty, I'm only growing in a small area (4m x 4m) so it was probably over-kill. For my...

So Ive been trying to look around to see about the benefits of using 3 400w switchable ballasts vs 2 600w. Obviously 3 lights will cost more than 2 initially but I was thinking of manipulating the light timers so that for the first two or three weeks of flower I could run a single 400w hps in...

Hey, so I'm seeing these weird spots on some of my leaves. They are dark in the center, with a lighter ring around them. I'm in week 4 flowering (SWC). Note, my plants have gotten very close to the light (sealed 400w hps) because they are in a bloombox so I only have ~3.5 feet of vertical...

I bought a pair of the Method Seven Resistance Perfect Color HPS PLUS+ grow light glasses. What a difference! No more weird feeling after working under the HPS and I can see what my plants look like in normal light. I got the glasses with the Carl Ziess glass lenses and am completely stoked...

I'm looking at moving beyond the MH/HPS combo for growing. Not sold on the mostly uber expensive and rapidly evolving LED market. At least not until prices come down. The HPS has been the go-to light for flowering our plants for a very long time. But what's been the driving factor in making...

Hey Guys! I've recently started my first ever grow, I have 2 white dwarf X critical mass autoflowers growing currently, ones 5 weeks and a day from seed and the others 2 weeks from seed. They're growing in 11L pots with Canna Terra Pro Plus soil mix, watering at 6.2 - 7 PH. Using a 250w HPS bulb...

Just bought 600W light system that comes with both MH and HPS bulbs. I started with MH and need to know when to switch to HPS. Any suggestions?

I'm thinking of adding hps to my grow....my concern is heat. I have a mall cab 33x33x40 I have good ventilation set-up and would use a cool tube...do you think I could keep the heat down? I would like to go 400 but if heat would be problem than I was thinking of Maybe a 250 instead...

I am thinking of switching from 600 watt HPS and switching to thousand watt LEDs to cut back on my hydro consumption has anyone had any success with using LEDS and if so what brands are good to use?

Hey everyone Im currently on my 3rd grow and am looking to find the best strains available to mankind! Im using fox farms ocean forest soil and nutes have a 4x4 flower tent with a 1000w Hps and a basement with 3 600w Hps full of vegging plants. Heres my current lineup. Humboldt-707 headband...
