Been a member for a few year posted once asking about a specific strain i was growing back in '08. I saw your other grow journal and was impressed i just had to comment and now i'm like a kid just waiting for the minute where you post some new info on this grow. I been thinking about getting some LED's and your journals almost have me convinced just waiting for your yield results on both grows before i actually make a decision. Your brave testing out these new LED Lights. I wish you the best of luck with this.

Here are some updated photos. I just started using Top Booster today, so we should see some major explosion soon. Plants look great, healthy and pumping out those hairs! Just found some slight powdery mildew on some of my leaves. I treated them with some Magic Green Foliar spray to fix this issue. Hopefully in a couple days, those lil white spots will cease. I stopped using Magic Green after the third week of veg. I should have just stuck with it until the third week of flower. I did not have any powder mildew on my last grow when I used the Magic Green until the third week of flower.

I'm really impressed--congratulations! I've been experimenting with LEDs myself a little bit (the 28w Grow Panel from Sunshine Systems is great for clones--they love it--I can't believe how good that light has been for only 28 watts--), and I was wondering how you're doing with heat with those two 500w Blackstars in a 4x4 tent. I've currently got two 240w Blackstars and a 600w Hps in a 4x8 tent (I've been using mixed lighting), and the heat hasn't been too bad to deal with--

Do you have an AC unit running in your room as well, or just apartment air? I'm curious if those two 500w Blackstars can hold up without any more cooling than general central AC for my house--

Thanks so much for sharing! Learning a lot :)

Thanks for visiting my journal dankog. Regarding the heat issue with the two 500s...it is not bad at all! I have a clip fan for intake, and exhaust, and two oscillating dome fans on the floor. My temperature never gets over 80 degrees! Even when I have my air condtioning off in my house, it only gets up to 85 degrees! You can definitely manage your grow tent or grow room with just your central air! There are so many advantages using these LED lights. I really love how cool my growtent is, because my plants never have any heat stress, or wind stress.

Your mixed lighting sounds intense! a 600 and 2 240w blackstars?? wow! Your plants must be monsters! Do you have pics or a journal up?

Here are some pics for you all. Magic green seemed to get rid of that moldy powder substance that was appearing. Unfortunately, I can't use it much longer because I dont want my buds tasting like it or smelling like it.

This $100 OG is probably one of the most potent OG Kushes I have had the pleasure of growing. If I barely touch any leaves or the buds, my fingers immediately smell like dank OG buds and gets really sticky!

Half way there! Buds are getting bigger! I have been getting questions regarding my ventilation. I have added pictures of my two tower dome oscillating fans, and my two clip fans that I use for intake and exhaust. Since LEDS don't give off much heat at all, I can get away with these fans. No inline fans for me, Im rolling like a silent ninja in this grow tent. I use my central air set at 75 degrees, and my tent is at 80 degrees. Without air conditioning with an inside temp at 80 degrees, my tent hits 85 degrees. How cool is that? And I live in the Valley of Los Angeles with temps right now at 100 degrees! I also took a picture of my gonzo odor bags. Hope that answers all your questions!

I like the squat bud structure. Classy looking OG.

Where'd you score that cut?
Ya my buds have been working out at the gym hitting up squats. lol. I got this cut from West Valley Caregivers over in Woodland hills/Canoga Park. Its the $100 OG cut, the best cut they have.

So I just took some pics right at lights out. I think I got the powdery mold under control. I just had to apply magic green to the infected leaves, and the next day the mold was disappearing. I just magic greened it right now on any remaining mold spots. Works pretty good. Leaves around the buds are getting triched up! I barely touch any of the leaves or the buds and my hands turn sticky icky and smells so sweet. I actually licked my fingers because it smelled so good and it actually tasted like sugar! I must be going nutz!

oh no mold....i can see it in the pictures like a white dust and yellow spots.....whats the Humidity like in the tent ?
That is the remains of the mold showing. I have been using Magic Green on the leaves and it is going away. I got the humidity under control now, using less air conditioning to let the grow tent temp rise and kill that mold

Did a trim job today, getting rid of any fan leaves with any dying mold, or fan leaves blocking any bud sites. Like I said, the mold stopped, I made my adjustments. Back on track

Nice ladies sleezy1, I am about to startup myself with a Blackstar 500 in a 4x4 tent running a 2x2 ebb and flow tray. I am in TX and its hot as hell too. I would like to grow in my garage. Do you think I should use a AC.? I am going try to do a 3x3 scrog. How many clones should i use?
