How do you get plants already so big to start with?

The places here in CO are getting stricter with only selling clones less than a certain height per the regulations. That's why I've been starting my last few plants from seed.

In LA and San Diego you can get teenagers that are up to 18" tall at www.emarijuanaclones.com - I got clones the first and second time, they've never had any problems.

I would want to start flowering closer to 12" (or less) with LED lights.

YMMV...

Yeah I know, you've made that point many times. But I don't agree yet - I might agree eventually, but right now I plan on using LST to get them oriented properly - mainlining, specifically. So flowering now would be counterproductive. Plus I want to give them some time under this light, 2 days under veg mode is not a test.

..although I will say this, I praised the clone place up one side and down the other and these plants while look correct strain-wise are way too tall. I was given them in one gallon containers but they had transplanted them the day before because there were no roots in the new dirt - of course they told me they did it days and days ago - so when I went to transplant to 5 gallon (because these plants are a foot and a half tall) the root ball practically fell apart in my hand. I let them know I knew they pulled a fast one and wouldn't be back. So it seems at the end of the day the only way to know if procedures are being followed is not to count on anyone else for anything.

I'm sure these plants will be fine, but I do agree they are taller than they should be at this stage of the game.

If you're going to top or LST to mainline then, hopefully, that should also reduce the height, right?

LED lights, even with 5w diodes, have KNOWN penetration issues but it's your grow so do what you want. *I* wouldn't want to extend VEG that long unless I was growing trees with 1000w HID lights but that's just me. There's nothing wrong with experimenting and not everybody is after efficiency. As I've always said, there is no one "right way" to grow.

That's why I'm not worried.

True statement. Howver, I'm not approaching this like I want it to behave like an HID - I know it won't. What I do know is if I treat it LIKE an HID then I'll have problems so this is new territory and I need to watch the plants very carefully. I'll do this particular test with no supplmental lighting per my agreement with CLW but what's interesting is how much different the product will be from the 750 HPS that is in the other tent.

Same guy, same lung room, same nutes, same strains, different lights. Should be a good comparison.

That's why I said I'd want to flower at/below 12" too. I wasn't saying flower now.

It's not much different than growing shorter plants with HID, the biggest difference is spectral, area coverage and penetration. I'll give you my prediction now; the 750w side will have bigger and more dense flowers with a higher total yield, assuming the plants for both sides are equal at the start of flowering. That also assumes that neither side has nutrient/pH/environmental issues that the other side doesn't have.

I'm looking forward to the test...

Exactly. For me it wil be worth it if the total savings on power is more than the difference between the harvests. I'd just as soon not have a small sun burning in my house all day, if I can keep from it.

Considering the price/gram and the difference quality/density has on price, it only takes a few grams of yield to make up for the small amount of savings, in power, that there might be. You'll waste more mainlining that you could save comparing even 1000w HID to LED.

You'll see...
