Molasses in Coco improves ion exchange, adds a natural chelating agent and provides some micros. I personally find that my terps improve with molasses at the end too, probably also helps prevent osmotic shock when cutting over from heavy feeding to more or less pure water.

I don't necessarily disagree, in Coco I thoroughly flush the pots with pH'd water and then give very dilute nutes with molasses 5 days before harvest, cutting to pure pH'd water with only molasses for the last 2 days. I don't generally suggest blindly following the feed chart though, as I've...

Rollitup, I want your input! I'll end up growing the winning entry, or in the event of problems the runner up. I've been selected as one of the testers for the Geyapex COB lights, specifically the LM-P4 model. This will be going into a Des Jardin 2x2x5 tent, making for 55w of COB per sq/ft...

It depends on the nutrient solution's tendency to adsorb in whatever medium the OP used. Organics tend to stick around longer than salts which requires a slightly different flush scheme, especially in soil grows.

Pyrethrin, insecticidal soap, neem oil, spinosad and diatomaceous earth . These are the tools of *safe* insect genocide. For spider mites, mix up fresh pyrethrin/insecticidal soap following the directions on the bottle. Some products like Safer's 3-in-1 come pre-mixed with Neem oil, which is...

Try finding COB lighting that isn't made out of parts from China or Taiwan. Heatsinks are mostly made there, COBs are made there, most drivers are made there too. With very few exceptions, your "Made in USA" lights are more like "Assembled in USA". The trick of the matter is buying from...

K guys. As someone who actually works with shippers as party of my job, y'all need to chill. Sending anything over about 200g or ½lb from China is pretty spendy because of the way shipping is calculated. Namely the fact that it swings the wrong way on 'chargeable weight' - it cubes out. $100+...

Flower times are kinda wonky. A lot of people start counting flower from the time they flip the lights, but it's usually better to count from the time that the plant starts setting buds.

Spider Mites. Spinosoad or pyrethrins, then pray.

That's a very nice driver and LED combo for the P4. Let me know if you need more testers.

Well, in case you need another tester for one of the LM-P4 units in a 2x2x5, here's the best of the best from my last 2 grows Dark Devil Auto @ day 43 http://imgur.com/a/bHwaL Dark Devil Auto @ day 62 http://imgur.com/a/dJ4Qx Dark Devil Auto @ day 71 http://imgur.com/a/jnqU1 Harvest -...

Looking very nice. I really want to see the results, especially how it compares to some of the pricey custom COB rigs like mine :)

Ditto here; I've done a few grow logs previously, but as i'm somewhat new on this forum (mostly reddit) and the fact that I lost most of my pics and logs when my hard drive ate it last year very likely disqualifies me - I mean, no point in posting a bits and pieces of a log.

Sounds like a nice setup. I've got my 4x2x5 just starting flower and a 2x2x5 that's currently being used for clones - got a really nice cut of Pineapple Chunk that I don't want to let go of :D The LM-P4 looks like it'd be the perfect size for vegging in a 3x3 or flowering over a 2x2. I think...

Well, I don't qualify, but I'd love to see the LM-B4 in action.

All my previous experience is with old Cree XR-Es and buckpucks, they're almost a different beast than COBs. :)

Thanks! this is what I thought, but it seemed too goddamed easy.

That's one way to do it, but then you'd need a 100k ohm push/pull with 10k ohm low limit resistor. The HLG data sheet has simultaneous dimming information, it's 100k ohm/n where "n" is the number of drivers. So for 2 drivers (what I have) you need 50k ohms on the pot and 10% of that value on...

Has anyone set this up using a pot? I'm trying to figure out the wiring to dim 2 drivers at once. I've got a 50k pot with a 5.1k resistor for low limit. My question is how are the positive legs connected? Do I simply tie both drivers' dimming wires together (+ to + and - to -) and the...

I just got my HLG-240H-C2100B's in and am starting the wiring process... Stupid noob question though, just because it seems too easy... for simultaneous dimming I have a 50K pot and a 5.1K resistor for the low limiter - from what I can see all I need to do is splice the + and - leads to the...
