If you are growing outdoors and you have only 8 hours of light and decreasing, there is nothing you can do to prevent flowering now that they have started.

24 or 18 and 6
Been running my lights 24 hours a day on my seedlings. Since I am growing autos, should I be at 18 and 6 now? Or should I keep running them 24 for the first couple of weeks to help veg up little before giving rest? This is my 1st time growing autos and 1st indoor grow in 20 yrs

Flower Light
Do you think this would be a good flowering light (on a budget) for a 4’x4’x80” - 1000 watt (5 plants - indoors - all hybrids ... if that matters)

Can I change my autoflowers light cycle withou reducing their yield significantly?
I am having humidity/mold problems and was thinking of changing the cycle so the grow goes off at noon ( currently it goes off at 1am and its winter and gets real cold with 88% humidity). Even if I stress them, it would be better to not have mold than reducing the yield, right?

Hi guys! What light should I get? The viparspectra xs1000 or the marshydro ts1000? I intend to grow in a 2x2 space. Would the viparspectra be as bright as the marshydro because its more efficient?

Questions: See photos. 1. MARS Hydro TS 1000 will not support 4 cannabis plants, correct? Support = Obtaining full plant potential. 2. The Chinese 3000K lighting won’t “hurt” my plants in veg, right? It’s just simply isn’t the lighting that works for veg growth, yea?

Distante between LED and plants.
The distance between the LED and the plants is 53 cm. Is it ok for the first week? I've read that a short distance in this stage is good to produce a not so tall plant.

Light strength
2 of my autos have been harvested and now I just have 1 mature plant mid flower and I've started my 3 other seedlings. I've got a tsw 2000 w/310 wts. Should I keep my lights at 100% for maximum growth or should I back off a touch to say 75 or 80%?

Best LEDs or small HID to replace 1000W dimmable HID for small space
I'm using a 1000w HID setup I had from before, running at 50% in a cool tube. It's loud and not efficient. Maybe it's time I switch to LEDs or a 250 HID. I don't want to sacrifice bud quality but I'm low on funds. Any recommendations for a good light that will fill this space?

Temporary 24 hours darkness, equipment issue.
My light ballest has broken tonight, my lights will have been off for 24hours by the time I can replace, the plants are about 2 weeks from harvest, would it damage the plants to start the light cycle (18 on 6 off) tomorrow after having the light off for 24 hours?

Auto seedlings, lighting question!
Hi! I have a question. I am just about to start my first indoor grow, it’s relatively small, only two plants, both autos. I am using the Telos 6 mesh LED for lighting but I am unclear as to when to switch the power from 25-50%? Is it when the first true leaves appear? Thanks

Light source change stress?
Can changing light source cause stress to your plant? Yesterday I changed from a CFL to a 150w Mars Hydro LED and this morning she looked a bit "sad". I took the photo straight after watering hence the damp soil.

Bad idea?
Will a mars hydro TS1000 be too strong for a 60x60x140cm tent? I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.
