hps

I'm helping a few people grow so I decided to create a series of infographics rather than overwhelm them with unnecessary technical details. This one is a comparison between HPS, standard LED lights and the new quantum boards (Samsung LM301B). Can anyone confirm or refute the numbers, please...

Yooo! Currently 10 days after germination on my first grow. I've converted a closet which is roughly 3ft wide by 2ft deep and 8ft high. I have space for 3x 5gal fabric pots in there and a 250-660w dimmable ballast with wing reflector and dual spectrum HPS that apparently retains the same light...

Hi! I have never heard before about this type of light for growing herb. They say its really great and it doesnt use much electrity too but its weird is that I dont really see people using it.

so I haven't been growing for the past year and a half. I got kind of burnt out on it and decided to focus on some other projects. Now that time has passed I am looking to get things up and going again. I have a 20x40 barn with AC, 200amp electric, and semi finished to work with. I am looking...

Hello, I currently have a rectangle hood around a 600w hps going in my 4x4 flower tent. I am installing UV Led strips along the long sides of the hood, and along the shorter ends of the hood I am interested in installing two new lights. I was curious, after looking into different options, I...

Hey Guys, I'm pretty close to harvest so wondering both for now and future grows as there probably is not much I could do in the next week or so. I'm growing Green Crack CBD and they are maybe a week out even less from harvest. I know leaves tend to go first but two out of the 3 plants are...

Hey everyone! Long time smoker, first time growing with any sort of significant lighting system. I’m running a 1000w vivosun HPS and currently have plants that were all started from bag seed. I’ve ordered myself 10 auto flower seeds from Crop King Seeds (5 Banana Kush, 5 Blueberry x Big Devil)...

hi so as the title says, i wanna use my 400w MH bulb with a 400w magnetic HPS ballast, i did some research here and on other places and it didn’t end with a conclusion, some said its ok and nothing to worry about and some strongly advised against it and their reason was that MH bulbs need lower...

Been out of the grow game for about 15 years and am more confused than ever on lights. back in the day I used a standard 400w hps for veg and flowering. worked finr but heat management was an issue at times and a blessing during the winter. this time ill be in a 4 x 4 x 7 grow tent in my garage...

Hello, today I bought a new HPS 600W grow light kit. The problem is with the magnetic ballast when I plugged the lamp it started smoking and I immediately unplugged it. Is it normal to smoke when first started?

F for respect.

So I have not disposed of this nice plant yet even though its preflowers seemingly indicate a male. Why is it growing more like a female? (Wide and bushy.) Bag seed

Transplanted from a 3 gal pot to about an 18 gallon shopping bag, which I’m sure I will receive plenty of criticism for, since it was already over potted in its original container. (Want to grow a massive plant for as long as possible.) Notice how even though there’s more leaves in the first...

Young plant seems all over the place, preventing canopy penetration. Should I trim any leaves to open it up? Under 400w HPS w/ supplemental lights.
