hps

hi guys, when do I switch from mh to hps bloom lights? Before or after stretch? There seems to be different opinions. What is best? Any advice appreciated

Id like to know how long i should wait before taking my rooted clones out from my t5's and placing them under my 600HPS

I was doing some measurements for a second 4x4x8 tent in my basement to house a QB to finish flowering in. Ive currently got one whole room dedicated to vegging plants with two 4x48" t8s (6500k), as well as a 4x4x8 tent with an aircooled 600 watt HPS. I wanted to use the leds to give the plants...

I got a 600watt hydrofarms light on Craigslist (used obviously). The light has been fine for the past month, but today when I looked in the tent it was much less bright than it normally is. It still has the same colors, just the intensity has gone down. I had an issue last night where it ended...

Newbie here! Used to grow in my closet when i was a teenager with cfls and experimented with outdoor grows aswell. Now I am a medical patient and am trying to grow the strongest medicine to help my chronic pain. BIG question is can I grow with HPS/Metal Halide lights in my home? its got fuse...

Hey! Just purchased a 400 watt MH wobble light and wanted your input on if you think it could work well for side lighting, I have a 10x10 space and was going to put the light in the middle as side lighting during flowering to penetrate the canopy better, I have hps lights above my plants but...

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 ..

I'm looking for data in 2 different grow styles. HPS growers: If you grow w HPS, do you have to add RH, or do you have to exaust RH? What is your RH and tent temp? If you can, give canopy LST and ambient temp. Just add like so... Light type: Growth week: Veg or Flower: RH: T: LST: LED...

What's up guys I was looking to get some input on my 1st grow room design. I will be using a section of my garage. The space is around 10'6 x 24'. I want to have 2 maybe 3 sections for flowering, vegging, and workspace. A buddy of mine is a grower and he's had great success with outdoor grows...

Hello, I am about to start an indoor culture and since it's the first time I'd like to know if I'm doing well. So, I have a 5x5x7 grow box (1.5mx1.5mx2m). Then I have a carbon filter, an air intake kit, two 600 W HPS lights, and a small fan. I'm going to use soil, root fertilizer for the first...

Bouta run a 4x8 tent with two 900-1000w hps cool tubes in 8 10 gallons pots. Im wondering what kind of yields I can expect from this grow. Im planning on using a high yielding strain and want at least 112g dry from each plant. Is this doable?

hello everyone, Prior to today I was an LED grower, but today I made the choice to add a 600w HPS light to my grow room. I know they can be really good combined (LED And HPS) But I’m not entirely sure how the lights should be setup together. I have a ballast with the light that is also capable...

So I’ve been reading for a long time on here and gwe I feel like I know just enough to be dangerous. Feel free to let me know what I could have done differently to make this grow work better. I ran into some problems with space in early flower and decided to super crop. The plant responded well...

Would like to know if can get my plants closer to lights by using 2 150w spaced about 40cm spart, Instead of just 1 250w HPs in the middle. I Read that you should leave a cm per 10 watt distance but not sure in this case. Grow area is only about 60 cm high and nearly a meter across. Just...

Hello everyone! Been off the forum for about 9 years (wow..) but now that things are settled I have had the opportunity to start growing indoors. I don't have much experience indoors, only from watching others really...and mostly hydro at that. Vegged for 7 weeks. pH 5.8 - 6.0. Water with tap...

I'm sure your eyes are important to you... So what are you using to protect them in your room? What other types of ppe do you use? Hats? Gloves? Glasses? Rep your gear here!

Howdy everyone, Here’s a start to my next endeavor. Traded some flower for some clones a week ago, here’s a little pic of them. I’ll be running 2 - 2x4 custom tables on casters each holding 28 ladies for a total of 56 under 2 1k HPS hoods ( sunsystem magnum xxl 8” ) and a few LED panels for...

Heyo! specs from the grow: https://www.rollitup.org/t/growing-height-low.979975/#post-14605391 I switched the plant yesterday and was thinking about how does it look to you advanced growers :) . Should i defoliate now or as i read later at day 15? I'm adding Big Bud Coco after week 1 and...

Hey Everyone , After doing lots of research on the subject , i still got a couple things i'd like to ask you guys about . Ive done many grows in the past (Indoor Tent+Outdoor) , so i'm basically quite familiar with most of the setups,techniques,etc .. But only done 1 successful grow in the...

I’m growing 3 plants ...they are bag seed. I wanted to know if using a bunch of cfl bulbs and led bulbs would be good or if there are any cheap led lights with power. Any suggestions? I appreciate any constructive response.
