light distance

Does anyone know why this is happening to my new plant? She is a Sweet Afghan Delicious grown in Doff coco, I'm feeding her tomorite and liquid seaweed every third feed at half the recommended dosage. she has been going for 41 days on a 18/6 cycle I'll be putting her on a 12/12 cycle in 24 days...

I've had a Sweet Afghan Delicious on the go for about 2 weeks I have been feeding about 50mls a day and spraying the top of the soil and the light (250HPS) has been about a foot away from the plant she has been thriving under these conditions, I'm just wondering if I should start watering more...

So I have a 6x4x6 grow box with a bunch of autos in dwc buckets. First...I grew too many plants for my box. Second I had 1 plant flowering when i started the other 8 (I know I know, 8? Really!?) So the light was over the flowering plant and caused the others to stretch. Now their too big...

This question about lights is probably as old as the first people who started to grow weed with electricity, and has been asked tons of times here too without end in sight. I didn't see a "real dedicated" topic about it either so decided to make one. Maybe some official or unofficial infotopic...

#1 I used a 300w led on my last grow, the results were 32g of dry bud, great quality but just tiny buds. Thought I'd give hps a go to see what differences there are aside from the obvious bigger yield. My set up is a 60x60x150 tent, lumii 600w hps dimmable ballast, RAM carbon filter attatched...

Hi everyone, This is my first grow. I am using a 1.2m tent with a 600w hid. My plants are about 3" tall now. How far away from my plants should the light be? Currently sitting a couple of inches off the "hanging bars" at the top of the tent. I've looked up distances , ive had and had 8" ...

Okay so I picked up a clone from the dispensary. Now I'm 2 weeks 5 days into veg and im running into a couple of problems, first off: Edges on top leaves are browining slightly. Secondly: New leaves that are growing on top are a very light green and edges are curling. I am growing 1 plant for my...

first grow, got my scrog screen almost filled, just wondering what the 'sweet spot' would be, how much space in between canopy and my 600w hps light. screen is about 4 feet by 4 feet and heat is not an issue as i have a heft fan sucking over the bulb. thanks for any info advice!

im wondering how much area my 600w hps will cover, take a look at the pics and see if you think it could handle covering about half of that tent? or even better question! can a 600w hps cover that whole scrog screen efficiently? its 45inches long and 40 inches wide. thanks in advance!

Hey guys I've been growing for about 18 months now but I've run into a little issue. I have decided to use my 4x4 tent so I could put in a few extra plants... I stared with the 4 that are budding in the pictures at about 5-8in above the highest cola... Now I have added the 2 plants on the left...
