Starter kits!
What can I expect from a 600w starter led, I know they're not meant to be great, but of 2 plants in 1.2 x 1.2 x 2m tent, fan kit, filter, etc. I know it won't great an there loads of other factors but say its a good grow, goes well what can you expect with these of good plant.

Lights went off and then on in flower [3rd week]
quick question, my breaker overloaded today and turned off power to my flowering tent. They were about 30 min away from lights out which I figure shouldn't be that bad, but while solving the power issue the lights came back on. Will they be affected and how? Thanks in advance

at the moment I'm using a 250W HPS and 2 40W CFL, this takes humidity down. When I will afford LEDs do you think that the humidity will stay as per night or drop down like maximum 10% or it will have same behavior as with hps/cfl combo? Thanks

Mars Hydro - TS1000 or TSW2000?
I have a 80x80x160 tent. I’m pretty set on getting a Mars Hydro in the future. but should I go for the TS1000 or the TSW2000? My concern is that the 2000 might get my tent too hot for me to handle and might be more than what I need since I’m only growing one plant.

Is it better to have one light unit that covers the full area of the tent or use multiple smaller ones? Im using 2 small leds. Is it better to have the ability to dim the lights or just have one power of intensity?

New update got my new grow light dialed in.. And the nutes helped a lot seen more growth in one day than I had in the last 23 days! I am worried that if I place the light at the recommended height (6”) that would be too much so I’m running the lights at 50% power and at 12” away

Breaking light cycle during flowering
Does breaking the dark cycle after half an hour of dark will stress the plant? I just opened the box 30 minutes after the light went down during the first week of flowering. Can this make my plants hermaphrodite?

Should I flip?
I’ve got my plants in 2gal fabric pots and I’m not planning on transplanting up. The plants are averaging about 8/9” and I’m starting to see small roots out the bottom. Should I flip to flowering, or can I get away with another week of veg?
