Where are you at? I mean the parts of my light are pretty generic, the LEDs from KB, heatsink (TME, heatsinkusa etc.) and the driver. But I had my light built by http://todogrowled.es/ simply because I didn't want messing with drilling heatsinks etc. Cost was barely more than for parts alone...

I honestly can't say anything whether Lemon oil/Peppermint oil would work...and also not whether it would be harmful for your plants. If you can and want to play it safe, why not just HOSE OFF eggs and mites with plain water as a temporary solution while you wait for stuff to come in the mail...

If you have spider mites and have a porch or a yard or similar area, HOSE YOUR PLANTS OFF WELL WITH PLAIN WATER, BEFORE you treat them with insecticidal soap emulsion and Neem. Yes your plants might look awful if you hose them but they will recover within a couple of hours. EVERY. TIME. And...

I don't need XYZ wash or "magic bug blaster" or whatever. Hose them with water, GOOD and then spray insecticidal soap and neem. https://www.rollitup.org/t/how-to-kill-and-keep-off-almost-all-common-mj-pests-easily.900261/ Chances are that most commercial products, "mighty magic bug blaster"...

https://www.rollitup.org/t/how-to-kill-and-keep-off-almost-all-common-mj-pests-easily.900261/ All the info you need. No need to "try" out all kinds of stuff where a lot of this is more anecdotal than anything. IMHO, insecticidal soap and Neem...BOOM. Just do it right like I describe in my thread.

Fricking BUGS, especially spider mites, white flies and whatever other type of aphids! There are two things I use, and I tell you why and especially HOW you need to use them for the best effect. There is no reason to buy hundreds of $$$ on insecticides since those two products can handle almost...

Adjust your ph FROM WHAT to WHAT? I can tell you that I have Neem products (Azadirachtin 3,2%), like the many AzaXYZ products and the instructions say to ph your spraying solution to 4-6. I have NOT done this yet and so far I have not seen any negative results. (In fact, each time when I hose...

I have a small grow area approx. 120x60cm (4x2') with 4x CXB3590 driven at 1650mA w/ lenses. Besides some recent bug problems (spider mites...) my plants are doing ok. Thinking that the CXB3590 provide all the light for my area (even too much in same cases) I started new seedlings at the...

You are not the first one "tweaking" the GHE formula. I ask why? I had some people say they had the best results just using the original what's on the bottle/chart. You're mentioning "changing rezy"....we're talking hempies here, if you use a rezy it's an entirely different story. (Ok...

Old thread, but I just got one of those cheap yellow ph pens which are sold everywhere, ebay, amazon, hydro stores etc. I found it TOTALLY WORTHLESS. The reading is all over the place and hardly ever "stabilizes" as it says on the package. I haven't even bothered with calibrating since there is...

I have previous "experience" growing organic in soil and I am about to switch to Hempy/Hydro with Perlite, Vermiculite or Coco. As most will usually do when they grow, they leave tap water out for at least 24hrs to let the chlorine evaporate. In an organic grow, I can see the chlorine really...

I am using a potting mix from a local garden center which is called "special substrate" w/ a bigass picture of a Cannabis plant on the bag. The mixture is very airy & spongy and otherwise feels and looks great, pretty much such as Cannaterra Pro or similar more expensive special mixes. It's a...

When I see a light like the above, I always wonder whether THIS would be exactly the same thing: 360 LEDs driven at 1.8V, Power Draw 780W, Cost ca. $390 shipped. Just looking at specs I don't see ANY difference just putting a bunch of cheap MH together and this light. In fact, I'd even say the...

A light based on 4x CXB3590, like I have Or a light based on 4x CXB3070, almost same performance. Right now I cannot recommend anything else but lights based on Cree/Bridgelux COBs. For that area (same size as mine) I think a bar 90-100cm (3-4') would be ideal, not so much COB fixtures with 4...

I like your T1750, it's very similar to what I have, 4x CXB3590 at 1750mA w/ lenses on a 90cm bar, although my light is DIY. MINOR annoying issue with my DIY light: There are holes in the heatsink, like for wires and for mounting fans. The holes are tiny, but it seems that over time small...

Nah, not over-thinking...was just extremely surprised that the housing including the area around the hole is not conductive.

Not wanting to come across like an ass, but seeing people needing to ask basic questions about grounding makes me think those folks shouldn't possibly build a light. We're working with possibly DEADLY voltages here, folks. As for grounding, I had my MeanWell driver bolted to the heatsink and...

Yeah I can get those "NASA" heat pipes with any standard PC cooler and make such a light. That's hideous. As for a GOOD company in Europe who sells/builds you lights based on CREE/Vero chips, I highly recommend todogrowled.es, based on my own experience. The guy, David, doesn't speak English...

So should I foliar spray them with CalMag? Hesitant to water since I have ovewatering problems and for now would like the pots to dry out. I guess a spray wouldn't hurt...will do that right now.

It's a "special cannabis potting mix" I get from a garden center here in Spain. "Professional substrate specially formulated for growing plants with special requirements such as aromatic, culinary and medicinal cannabis. The mixture of peat, coir, compost and perlite brings lightness and...
