That Pineapple Express was grown from seed, and bred by G13 Labs.
I received it as a freebie awhile ago and decided to grow it out earlier this year, I'm glad that I did.

Good to know!

I'm running g-13 PE under solar storm and 900 watt bs and they come out real fat and fruity! How long do your go for it says an 8 week strain but mine are week nine and still fattening! I'm thinking day 77 when I take down my sour deisel is when I'll take these down

Dickhead! Been wondering when you were gonna update us on your grow. Good stuff!

For instance, the brightest 5mm white LEDs output something around 2 lumen with a forward voltage of around 3.4v and a current of 20mA. That's an efficiency around 30 lm/w. Most 1w+ LEDs can output 100 lm/w, that's more than 3 times more light for the same amount of electricity burnt.
Moreover, you don't need 200 pcs LEDs if you use higher power so it is easier to put together.

In conclusion: my advice is not to go with 5mm LEDs.

hello patrik and thank you so much for your answer, but you are wrong at some point on what you r saying , the 5mm LEDS don´t put the same amount of electricity of 1w led, that´s because the 5mm are 0,6w or less and the 1 w are less than 1 w depending on the led i thought. andthat´s your mistake , they don´t put the same amount of light. besides of that thank you for your answer and I think i will be puting 3w led or 1 w led . but the amount of lumen is not so important like the spectrum and you know that that´s why they put red and blue , 2 bands . instead of puting all white that has better lm

Obviously you don't know what you are talking about so you cannot say that I am wrong.

To answer short: YES the luminous output of LEDs matters. Whether it is counted in lumens, milliwatts, µmol/m², etc. doesn't matter but the luminous efficiency of each LED DOES matter. And what I am trying to say is that 5mm LEDs (which are closer to 0.06w than to 0.6w btw) have very poor luminous efficiency when compared to high power LEDs.
Comparing lumens alone isn't optimal for some reasons but when comparing same color LEDs it is a very good starting point.

Ebay my friend you can find them by searching for hi_iq that is the sellers name. ( I am not that person nor am I affiliated them in any way ) however this seller DOES NOT sell the LED's specifically for the purpose of cultivation. but they seem to work decently.

My Pineapple Express was ready at about 9 weeks, but every plant is different, let the trichs be your guide.
