todo depende del tamaño de las plantas! tal vez despues de la 3era semana de veg es cuando realmente empiezan a necesitar mas luz!

Marshydro FC oder FC-E
Lohnt sich der Mehrpreis der FC Serie im Vergleich zur FC-E Serie? Auf dem Papier ist der Unterschied ja eher marginal.

Seeking a reasonably priced light for 2x4x6 tent (still)
I'm interested in picking this up. Thoughts? I have a 2x4x6 tent. I believe it's 50w x 8sqft is 400 watts needed? https://www.amazon.com/iPower-Digital-Dimmable-System-Reflector/dp/B006GGP8P4/ref=sr_1_2?_encoding=UTF8&c=ts&dchild=1&keywords=Plant+Growing+Light+Fixtures&qid=16110

Led to hight?
Hi everyone. I'm thinking that the Led Light is to high, its around 70 cm from the plants, should I lower it down up to 50/55 or leave like that until Bloom, and on Bloom put it more close? Some more help on the grow its always appreciated. They seam really beautiful by now 😃

light bleaching
Why are my leaf tips getting bleached still? I have the light 18 inches from the canopy which is what is recommended for veg, and that's only around 400umol/m2s but the leaf tips keep burning. Temps are low if anything, consistently between 65 and 75 farenheight.

My grow tent is sitting in my basement, which normally sits at 10C in the winter, so I set the heat in the room to 18C and the LED and 2 fans heat it to 20.4C in the tent. Anyone have a similar setup but using their grow lights as a heat source? Heating a basement is expensive.

Darkness before harvest?
So is there really any benefit to give a long period of darkness before harvest? Once again, I'm on the fence with this...

Is that possible to do grow light with Samsung LED strips?
Going deeper into idea of doing the quantum board from scratch but instead SMD LED's there are lots of strip LED options. So I want to ask you guys if I have an aluminum plate with a heat sink and coolers, can I fix those stripts there? Or can I rip them off with a heat gun?

Mars Hyrdo TS600 - 100w but mistook for 600w
I've recently found out that the led light I have which is a Mars Hydro TS600 is not in fact 600w and is actually 100w. Do I need to compensate in any way? My plants look healthy but short, I don't want to put the light too far away that it's ineffective, how close is too close?

amount of sunshine for autos in late flower - open air, outdoor grow
We're getting 14-15 hours of strong sunshine a day. Now that I'm late flower, should I move my autos into a spot that will get shade for half of the day? Seems like they may not need to be pounded by this much light/heat at this point and could use more down time.

How to tell if light is damaging plant?
I'm using a Mars Hydro Ts600. Manufacturers advice is to keep height at 12'' minimum above the canopy in flower but other growers report it can hang as low as 10''. In identifying optimum height how would I be able to tell if it was too low for my plants? What should Iook for?

LED distance to plant advice
Interested in how close I can get my 630w LED with a rating of 2.7μmol/W and 1700 PPF to my canopy. I had it hung 48cm (19 inches) on 380w and just upped it to 500w day 8 in flower. Does this sound too close at 500w or is this ok? Temp is 25C (77F) humidity 55%.

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.
