super close

.

They look awesome!

Thx

Here are some pics of the gdp, came out perfect, I used an lst technique to get so many tops, when I lst I got 13 tops, all the same height, so really I didn't need lots of penetration. the buds are thicker and denser this time around, really happy with the penetration, using the lst opens up the plant so you can keep it around 3 feet but super wide, like a kid and play hair cut. This is how you get good yields with this light, rather a tall plant. I also used smart pots, I put t5 for additional pars and better penetration on the lower stuff and around the edges. RO water, had no pest problems, kept constant ph 6.4, never over watered, kept appropriate distance from canopy, perfect temps and humidity, and used a 30x viewer to pick at the appropriate time. These are nine week plants, half way through week 7 I soaked the soil in a final flush mix, let it sit for three - five min, then hit it again, you want to give it a chance to dissolve the salts and built up nutrients. The thing with led is the plants drink slower, so timing your flush with the end of the cyle is a little different than using hps your soils drys up really quick. after for days I was in week, 8. Hit it with ro water again, after about 4 days she was dry again. then I cropped welcome to week 9. This is my third grow with led and these are by far the best results, ill post weight when shes dry, I still have og skywalker going not quite ready.

Some tips on when to harvest and curing.

So this is what I do, and ill explain why to. Lets start with when to cut you're plants down, some people leave them in the dark for 48 hours or whatever then take them down, the logic I suppose behind this, crystal productions at night, and mass during daylight hours, so people think they get more resign production. I read a publish article by a phd, ill post the article later, might not let me. The plant produces a by-product during the daylight hours that enables it to produce crystal at night, it produces exactly enough to get the plant through 12 hours of dark, so in other words, the plant doesn't have enough resources to produse crystal after 12-14 hours in the dark, it wont hurt anything, but doesn't add more crystal. So the best time to crop is a second before your light turns on, don't let it turn on of course, keep them in the dark. IF you cut your plants while the light is one, your bud wont potentially taste or burn as well. The very second the light turns on the plant starts to pull nutrients stored in the soil and roots, so that's why the real pros cut them in the dark, smoother smoke, and lower curing times. Some people cut down the plant during the light because it smells more, but at what cost right, I would rather have smoother product, and the peace of mind knowing that even if I didn't flush everything out, the plant hasn't had a chance to pull any nutrients from the soil anyways. And if you ask me after you cure and dry it the smells is exact the same as if you cut it in the dark, it only reeks more initially, which Is a negative side effect for keeping the smell down and not being a heat bag.

I left my plants in the dark for 14, them cut them, I like to cut off all the leaf right away, its eaiser to manicure, my shits stupid sticky so pain in the ass to trim, if you do it right away the leaf is still erect and super easy to trim nice. Then I put them in a seald cardboard laptop box, perfect size, so no buds are touching and I slide it under the drain table in my room so it takes care of the smell, keeps them in the complete dark, and my room is at 57%humidty right on all the time and ideal temps for curing with all the leaf cut off, a bit lower if you leave it, that way I don't have to use a separate room, once I can snap the stem, into the cvault for a week, I flush properly so I never have to cure for long periods of time. just be carful if you trim all the leaf right away, if she drys to quick you will get hay! putting them in the boxes and in the temp controlled environment, she works out perfect.

even the stem was coated in thc, never had that with hps. I probably would get more of a yield with hps, but would of had to deal with stretching and adding blue, and dealing with heat, watering and using more nutrients, running an ac all the time, all that power. inline fans, inline fans, running a 220 line, bla bla bla. and I find the quality of the weed to be better with this 800watt led, taste smell, hash count, crystal, this light 100% for sure if you know what your doing and play to this lights strengths you can get kick ass results at a much lower production cost. Ill post my final count, thinking around 1g/w again, 4-6 onions per plant, both my strains are high yielding and I used lst so that helps out mega,

just think about how much eaiser and cheaper I was able to produce 1g/$ man just the nutrients and not having an ac on all the time saves you so much money, now add a blue mh to that or another 600 with a blue bulb, or however you plan on getting your plus, now add an inline fan, now you have two lights running multiple inline fans humidifiers\dehumidifiers, ac is now running even more, now you have two 220 lines to run. to me its a no brainer, led is much better and more efficient for people doing small grows in a 4x4 area. just 5 years ago the technology was crap and couldn't bud at all, caint wait to see what comes out in the next few years. once I get the 880 and put it on a light mover and keep it in a 4x4 space, I can put it closer to the plant which means better penetration even canopy! and probably better results

I would not recommend led for large scale grows, not these fixtures anyways, not enough intensity,

Large scale grows you need ac's and multiple lights running anyways, if your going to go hps, at least do a 10x10 space or bigger to make it worth it. Plus now with smart meters and all that jazz, plus rising cost in electricity, the hvac and nutrients savings from the led with a slightly leser yield seems more enticing to me. You can clearly produce an amazing product with this light, and it eaiser to control your temps and everything else, definitely harder to grow hps, I know lots of hps growers that have 90degree temps and humidity problems, buying bulbs putting them in cooling fixtures, and they still yield likek 2-4 onions a plant, because its harder to grow properly with hps you gotta know your stuff, gotta have them room cool. and you have to have blue and red to get 1g/watt with hps. so most people that do grow hps have so many problems they get low yields anyways

This is an example of what I'm talking about, this is two plants, that's it! fanning out the plant with lst, nice an even, 14 tops on the one plant plus undergrowth and 19 on the bigger one last week, coming down first sign on yellowing, that way you know the plant has used up its stored nutrients, you can also taste the plant break off a leaf, if shes sweet, shes ready, if it taste bitter than still has stored nutrients

I had to take rope and tie it around the plant to hold it together, all the branches were hanging because of the weight, because its almost done I wont bother yo-yoing each branch and opening it up. Ideally that's what you wanna do
