started grow question 4y ago
Looking to upgrade my maxibright daylight pro 8 bar led light to something a bit bigger and beefier. Something that has a span of 1.5m x 1.5m and ideally more power. 1000w etc. Any suggestions on what works well and why you like it? Thank you

Lighting Question
If anyone has a Mars Hydro tsw2000 light can you tell me what the function of the two switches are? The only thing i could find was something saying that one is better for veg and one is better for flower. Can anybody tell me which one is which? cant find much online to help.

11/13 for flower
I need my grow to finish flowering ASAP, due to extenuating circumstances... I’ve read that flower can occur faster under 11/13 with some loss of yield. Does anyone have experience here? How much will yield and flowering time be influenced?

NEED SOME ADVICE! Change to LED from HPS? which ones are good for tent size? Which ones are good for good yields?
I've got a 4x4 tent with 8 seedlings in cups but will be in 11L pots. Currently I had a 600w HPS light but my ballast busted today. I have a back up CFL 150W not to mess up the light schedule. Thinking about changing to LED lights, I know it'll be cheaper but I want same yield...

Should I lower my light during flowering?
I'm at 24 inches away now, should I lower the light now that she's in full bloom? I went with the recommendation of Mars Hydro and burnt up 3 seedlings as a result. Sadly I only have one bean left of my Fastbuds over this crucial mistake. Running a Mars Hydro SP 250 keep at 36in.

Spider Farmer sf 1000 light height inquiry.
I am growing in a 2x2 spider farmer with a SF 1000, currently the light is 20" and only 80% power. It seems like a powerful light and don't want to overdue it. Should I move the light closer and turning up to 100% power for the rest of flowering?

Effect of light only? Really?
These girls same strain (strawberry cough photo), born on same day, same medium same feeding except the one on the right was removed from the light about 3 weeks ago and put outside. I thought dark green from nutes, seems the light alone makes such a difference? 45 watt LED

Is your machine helper leaking light?
Everyone has their ACs and dehumidifiers and whatnot machines in the grow space. Are you covering every little light of those machines in the flowering chamber? Many hermies will be avoided with some aluminium tape. Stay safe, cover those lights and grow ganja!

Ok this is hard. Sf 4000 driver failure & idk what I did lol. Plugged into extensions and a surge protector but aside from flipping a fuse every once in awhile this came out of nowhere. Any help would be great or even just where to start. Already checked connections.
