IS 120 watt going to be sufficient to cover a 3x3 area ??
120 actual watts or are they advertising 120 1w diodes or something along those lines. Theres a big difference in actual output and theoretical capacity of an LED due to thermal issues.IS 120 watt going to be sufficient to cover a 3x3 area ??

I do not see anyone who try it to tell me that they don't work, I only read that it doesn't work..5mm LEDs are not near as efficient as 1w, 3w/+ LEDs, it would be a waste
You can still make your own DIY panel with high power LEDs that you find on electronic supplies stores (farnell, radiospares, etc.) or off ebay. They are more efficient and as they are more powerful you need less of them to output the same amount of light.
That Pineapple Express was grown from seed, and bred by G13 Labs.Nice... where you get your pineapple express? clone or from seed (if so which breeder)?
Good to know!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.
Simply put: high power LEDs (1w+) output much more light for the same amount of electricity than 5mm LEDs. Using 5mm LEDs will certainly work but it is stupid because the efficiency will be very low.
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.
My Pineapple Express was ready at about 9 weeks, but every plant is different, let the trichs be your guide.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
Different techniques can cause longer flowering as well, for example LST/tieing down.My Pineapple Express was ready at about 9 weeks, but every plant is different, let the trichs be your guide.
