Hey, got a couple electrical questions... If you put a LED PCB (Multi-chip or Star) with LEDs onto a heatsink.. Is the heatsink safe to touch? Is only the +/- on the PCBs electrically conductive? or is the whole PCB? I'm thinking about trying a few multichips on heatsinks... or I'm also...

Yeah, that was a nice pic.. but I still feel that it doesn't quite do the hans justice. My current grows colas are like 2x that size... =D

http://www.amazon.com/gp/product/B001CCGYU0/ I think any of these cheap CPU heatsink's would work well--if it can cool a cpu, it can definitely cool a LED up to a certain watt. Buying some decent thermal adhesive/paste *could help too. If my multichip Flood builds go well, I will try some of...

looks like a nice spectrum, but I dont know what model leds they use. Sorta expensive too. Cree cheaper with less spectrums tho http://www.ebay.com/itm/NEW-100W-Red-Blue-Dual-Colors-Cree-XPE-LED-for-100-Watt-Grow-Light-Bulb-Lamp-DIY-/231063019108?pt=LH_DefaultDomain_0&hash=item35cc6dde64

This is the cloning dome made with 2 salad containers, and a glass of water with an airstone in it. It also sits on a heat mat due to fall/winter. Here is the Vegan Mix before and after coffee grinder.. ground up the chunks(of azamite?) and turned the mix into a brownish powder.. =D On...

Here is the Vegan Mix before and after coffee grinder.. ground up the chunks(of azamite?) and turned the mix into a brownish powder.. =D

How many tsp/gal of the organic Rx powder are you feeding per watering?

awesome did you use it alone? could you go into a little more detail on how you used it / how much per use / how often? thx

Hey, I was wondering if anyone could advise on how to use this product best. Generally it says to add into the soil when mixing it. Also they say dressing the soil will work. Dressing doesn't seem to help much. It's a little too coarse to be mixed right in with water. But Ive ground some up in...

Yo, those plants look great have you added any Magnesium, or do you not need to? I have both the fert you are using and the Down to Earth Vegan Mix. Doesn't seem like there is much Mg in either. Im currently running the VeganMix, but its not quite powder--its quite coarse and has these black...

Perhaps this is the reason Hans has not used White Light until now... He only just now added some.. all XBD. The Red/Blue XPEs might be really good, whereas the whites are not great. Maybe on to something.. or maybe my XPEs will be garbage... Ill let ya guys know either way hah

Also, I got some arctic silver thermal compound for these XPEs.. is this decent for LED chips?

textual update first.. =D Ill get some pics comin' Cloning Situation So last update, I was having trouble cloning with the soil method.. so I took 4 emergency flowering clones. -I had Roots on all 4 new flowering clones within 14 days (I will expect like 10-11 day roots with heatmat) Im hoping...

How many Watts, and what type of LED do you have there? From the looks of it here.. that node spacing seems pretty tight

Well, hans driver is 60w and 700mA. Here is a pic of the little reflectors.. angle is almost the same as the Floods angle that i'm going to use. I got 3 new LED chips, and 3 Drivers one driver is: Input: AC100V-240V 50/60HZ 0.36A Output: DC24V-38V 1000mA+-5% the other is 30W AC85-265V...

Yo, I want to bring Cree XP-E back up for a sec. Turns out that XPE what is on my model of the hans panel. my hans panel specs: And I would say the hans is quite beast with its XP-Es.. So here is an example of one I just got. 30W Cree XPE 8 Red 2 Blue Power: 30WEmitted Color: Blue+Red...

Wow, that LST operation with the bigger pots looks awesome. What strain? Also, Do you take the glass front off of those Flood lights? So heavy..

Well, how bad can these XPE's really be? For whatever reason the XPEs are a little more expensive than the XTE. Could it be worse than the no-name chinese LEDs that were supposed to work on these floods I got? Also, what is the best viewing angle? 90 degrees? I dont see any of these chips with...

Those 50w are nice, but the main point of what I'm doing is filling up these empty 30w LED Flood Lights(have 3 of them). I have 4 hans panels running, so these new chips would just be for additional light. (white light pref, since the hans has none) And the only 30w cree I see are the XPEs...

ah my bad.. mixed them up. I meant hans went for XBD "4 Cree XBD Royal Blue, 17 Cree XBD 701 Red, 2 Cree XBD White and 10 Osram LH-CPDP DeepRed Rebel Led's" edit: so which of these chips should I be looking at? XPE XPG XTE. is xte the only decent option? I already have lots of blue and red...
