light

Because of the immense size and distance of the sun from earth, and the action of global weather patterns, the earth is bathed in solar wavelengths that get light to all parts of a plant, not just from above. So, logically, in an enclosed space, supplemental side lighting is necessary to...

using mars hydro 320 pro. week4: week5-6: please share if you something wrong.. i think light is a bit powerful because i see brown burnt hairs on top buds. :) :Namaste:

59 days into my first grow. 1 Northern Light auto. 300w LED. My LED has a Veg and a flower switch. Veg light-93 watts, Bloom light-180 watts. About 10 days ago, I Initiated the Bloom light in addition to the Veg light. I am on an 18/6 indoor soil grow. From the 2nd day of Bloom light...

Hello everyone I am new to this site and LED growing. I have a red 880 grow light most of you know what that is and I am having problems getting any stretch from my plants. Beans popped around Nov 22nd to 25th Critical and Bubba Kush:lot-o-toke: they were under t5s for two weeks and then put...

Dear Fellow Growers. I hope you all are well. Once again, im here to ask for help to identify and solve my current problem. Im hoping you can shed some light (lame pun intended) on my current grow. Which happens to be my FIRST Grow... so please be patient with this NOOB!.... hmm...

Hi 420, new grower here. I just germinated 10 white widow seeds. They all cracked (10/10 props to Crop King) and grew taproots, and once the taproots were about 1/2" long, I planted them into solo cups. It's a coco coir / perlite medium. Moistened with pH'd water. I put the cups under about...

Just a new guy getting into the hobby. Started my 1st grow just last week and now have new sprouts. Growing MOC Auto Pilot XXL and Blueberry Domina. Working in a 4x4 tent /air cooled 600 watt hps with carbon scrubber. One question I have is the sprouts seem to have stretched a little so I...

Can anybody tell me whats going on here please. First time grower and i have 4 plants growing in soil under 600 watt HPS light in a 5x5 tent. Light is at 3ft above and temp is 25c, RH is 40%. Is this stress? I did some topping about a week ago. Nutes are Flora Nova Grow 4-7-10, other 3 plants...

So after a first grow that didn't end up quite as planned but was valuable in terms of learning. Im finally set up to go for my second round!I learnt a lot through out my last grow with help from a few of you here and this time im hoping will be a complete success! So without further ado...

Hello,so i came home today and my light had took a shit and i just started my first day of week 8. And as i was switching to a shitty back up light it fell and broke the mane stem but it's still attached and i got it hung up. My question is should i switch out my nutes and start my final...

A few years back I got few ww x c99 seeds from Femaleseeds.nl and really liked it. Because it was my first time grow of that strain I didn't take any clones from her. After harvesting those two plants I tried to get some information on the strain, but was always given rather vague information...

Hello all. I have a problem that I haven't heard of yet, so I'll post here and see what the Wizards of the Forum can come up with. I started my plants Dec 1. Since they popped, I've been BOMBARDING them with 600W MH light, originally dimmed down to 500W for the first couple o' weeks. I...

Ok before we start...yes I know but funds very limited at the moment.... So I bought a galaxy hydro 300w off eBay, very purpleish light and has been working great but my tent (2.5x2.5x5) is a little big for a single light source so I've been looking at a second one. Due to budget restrictions...

Greetings! Hopefully, someone will have an answer for me. I recently was given a 1000 watt HPS and Metal Halide grow light, well, the shield and the two ballasts. I would like to try to grow some of that auto flowering Northern Lights so I'm curious, is that too much light and heat? I would...

Hello. I am pretty new to growing & have a chance to purchase a used Marshydro light for $350. It is a 600watt light. Is this a good purchase?

Hi everyone! i have a problem. I think they're too small. Is it? Using LED light (2 Lamps 600W). Ph was 6.2, now changed to 7. What's can be wrong?

Would the moon constitute a light leak for an outdoor grow? If so, why would a tiny soft light leak matter in a grow room or tent? I'm brand new at this and trying to understand a lot really fast. My main concern is leaks where the fans are. Thanks, Joe
