When you up-pot a plant, you obviously want the plant to fill out the bigger pots with roots. My question is whether giving the full strength of nutes after up-potting would slow down or hinder root growth - which would suggest that one shouldn't give full strength (or only little nutes) after...

I have no reason to believe the COBs from Kingbrite would be fake. If that were so, Jerry hardly wouldn't have the reputation he has here and elsewhere. The same thing with the MW drivers. He would be stupid to sell counterfeits.

I have another "interesting" thought to add here. Some "miracle" products are on the market which are SAID to be very effective for aphids, but the makers don't say what they contain and claim some pseudo-scientific nonsense about "frequency water". What I think is that the "secret" there is...

I don't think we have "Dawn" here, but I found the blue "multi-purpose" cleaner thing in a sprayer super-effective for ants too :) I actually don't think it hurts the plants to make a solution that contains 2-3 drops of actual dish-washing soap, I did this yesterday since I sprayed vegetables...

When I spray, it's slightly "milky" white, if you mean this with "white buildup"? I NEVER wash it off - this is the point, it needs to stay on the plants for max. effect.(I never had ANY negative effect on my plants from spraying with the soap and Neem, ever) In regards to spraying in flower...

>> I think I can definitely make a Cree COB calculator that will take as an input any amperage, instead of dealing with the preset ones. It will take a good amount of time as it will be quite tedious to input all the points for all the different cree cobs and bins that are in the calculator. >>...

Man I am so glad I could keep the light, thing is I love growing, also hot peppers etc..it's really a big hobby of me. As for the case, even IF it would go to court....wife has prescriptions and told them she is smoking MJ for anxiety (which is true), so I don't think we would have any troubles...

>> Electricity is expensive >> Tell me about it....A/C...right now it's about 100-110deg...trying to keep electricity bill under €200. Some massive grow with 1000W etc lights would be impossible respective would cost a fortune. (My LED grow light currently is 250W fully turned up which is very...

H! I didn't know we had a Spanish thread here. Near Alicante, living here for about 6 years now. I can only confirm the cheap living here, and ESPECIALLY what you get on decent groceries for €20, it's ridiculous. If I get groceries for €20, I need a trolley or two to even carry all the stuff...

Does someone have the actual *spreadsheet* for the CXB3590,36V, 3500K, CD bin? (and not just the images) Thanks! :)

Question for you: Would you like to post (or send to me in private) the JAVA source code of your tool? If not, I can of course understand. It just itches me to add more data points for my COBs, at the amps I drive them and maybe add a section for easier input of the growing area. (I think it's...

Yeah when light is more intensive, it's more intensive... :) But in all seriousness, of course penetration ability is nothing else than a result of light intensity. (ie: photon density that a light emits)

Yeah usually it takes 3-4 weeks, never had any problems with China before. Anyway, those Will linked are €13 shipped, which is too good to pass...so even if they take very long it's a good deal so I will buy from them, won't get them cheaper I think.

Will, I am buying often from China (ebay, etc.) but right now something is seriously off if you have something "cheaply" mailed, aka China registered "air" mail. I have two non-related orders coming from Shenzhen, waiting for them FOR TWO MONTHS now. So if I could I'd want to avoid buying from...

Me, I'd need some two 80 deg glass lenses but Jerry doesn't want to sell without more stuff in the order :) I can't find any vendor in Europe who has them...

Are you referring to my question whether someone in Europe has the 80 deg lenses? If yes, if someone in UK etc. has two of them over and wants to sell them please PM me :) The same maybe if someone from EU is about to order from Jerry in the next days, they could throw two of the 80deg 100mm to...

What distance did you have your lights at and with how many amps did you drive your COBs? This might also play a role in the way they grow. Mine also got HUGE leaves by the way

Does anyone have the measurements of the holes for the 80 deg Kingbrite lenses?

Ok I made the stupid newbie mistake not having pruned my plants, they got WAY too leggy. Rather than worrying about the right light temperature I now cut all my greenhouse peppers, learned a little about pruning too. I really want the light energy going into fruits and flowers, and not 6ft tall...

How were you able to keep yours short and bushy? Did you top them? The four in the white pots I JUST repotted and moved from my greenhouse upstairs. Those have been grown from seed to now with 3500K 80CRI. (The size of those MoFos doesn't come over in the picture at all, each of the white...
