Nothing wrong with wanting to cut down on the electricity bill.. Its Just your putting your plants in a state for the sake of what is essentially a couple of cents, when you could of ran 18/6 and had bigger plants without them trying to flower.

Well if you want to put them outside soon, I'm not sure why you'd be going for less hours of light instead of more, so they are bigger when you do.

There's some comparisons online. From what I remember the top end bulbs are 4 times the price than some of the new cheap ones , but only fractionally better . Just Google it or search YouTube.

That seems a bit backwards.

It's a nice light. What price are you seeing on them?

HPS are still being manufactured by the boat load. It depends where you live in the world as to what green laws or taxes they put on such things.. But I'd say the likely thing that's happened is your grow store can make way more mark up on LED lights than they can HPS set ups. If you want one...

You get rapid growth when you flip, Less mobile nutrients can't keep up with the growth, but it will settle and green up soon. If you didn't have issues in veg , your not likely going to get them once you flip

Generally, when you flip and they start transitioning, new growth will be light , its because certain nutrients like sulphur and iron are slow moving and then they will green up later. Orange spots could be CA

Well if AN was the problem there would be thousands of threads about it all over the Internet. I'd look at your genetics

It's unlikely you'd need a humidifier , it's going to get more humid when there's plant in there.

That's the best way to do it. Oversized will perform better and last longer

I'd do that again lower down and lower your light

Possibly, but in many cases more light more stress and less speed. If I compared it to hps or mh the growth (when environment is perfect and plants happy) Is far better under LED , even at 9w a square foot.

100w will stretch to 2x2ft in flower. It's weak but you'd still get reasonable results. That's 25w per square foot. In veg you could cover 3x3. It wouldn't be ideal light spread, just because it's a single panel. I've vegged under my 600w leds at 25% over 4x4 and it still gives good results...

Unless you're @Moflow :o

These were shared on another thread last week, they're on offer at the moment. https://www.arrow.com/en/products/sl-b8v3n80laww/samsung-electronics What I'd do is Google DIY strip builds And growmau5 on YouTube to get a grip of the basics.

Didn't see this until now. Let's just say you've 200w at the moment . Because they aren't very efficient. I'd be looking 500w more light if your going to light 8x2.

The way I'd look at it, Sf2000 is a 200w light, recommended for 2x4, it's not really enough for that space in reality. A 400hps, you could use it in a 3x3 , still weak though. Probably ideal for 2.5x2.5ft. Even the shape of space you have to work with is a factor. The ambient temperature...

Aah.. could be useful then.
