Sorry about that. Thank you for helping me correct order.

@CobKits, I messaged you on friday about the order that still hasn't been fully delivered. I can see that you've been posting on here as recently as today, yet choosing not to respond to some pretty simple questions from a client, who did not receive their entire order. Will you please...

Awesome! Thank you both for posting. To the technologically illiterate, you are light lighthouses; lead the way!

What are you using to automate your room?

Thank you! I got a bit too enthusiastic; still haven't figured out an ipm. What are your thought for ipm through flower?

Auto-text messed up, title asks if pistils and flowers will regrow or heal.

Week 2 of flower, I did a foliar spray with humic acid and agsil 16h, and left the lights on. Initially, I only sprayed a small portion, however I later sprayed the majority of the crop. In a short period of time the pistils began to look like this (see attached). Will the plants heal/still...

Thank you both!

If any of you have used a sun cloak, can you share your experince. Has anyone built something similar, something with vertical led strips? Can you point me to it, or elaborate about design? I'm thinking of building something similar: 4-5 foot led strips; should I use 1, 3 or 5 watt? How do...

@KryptoBud and @doobie57z, thank you both! I was minutes away from ripping out my flowering plants, but I'll give it some time.

Nope! But it's northern co, so it's legal!

At 1 week into flower, the lights were left on for 36 hours. A few weeks later, these are starting to show up. Are they hermies?

Thank you, btw. I used it too late and it ruined 1 of my plants. The others, less than 2 weeks into flower, remained pm free.

I'd like To passively cool 4 72v CXB 3590 to 75 or 80 watts. There would be 2 per driver now, and 4 per driver once the 320s are released. If actively cooling would increase efficiency, id like to attach fans to the units. Thanks @welight

@welight, can you recommend any pin heat sinks good to 80 watts?

@VegasWinner, how many watts can it cool passively? Doyle know the formula for c/w? I saw the formula on here somewhere. Thank you for the help.

Can someone help me with my shopping list? First, I'd like to run 4 cxb 72v cobs at apx 75 watts. Eventually I'll get more cobs and focus on efficiency. Are there pin or fin individual heat sinks, not like the heatsinkusa model, that can actively cool apx 75-80 watts? I'd like it to be able...

@greengene707 Can you post links to your links for the pin heat sinks? Thanks....

Hey doc, Do you have a thread for your process: soil vs hydro, insecticide/fungicide regime, etc? Thanks

Hey supra, are there any pin heat sinks for 60-75 watts passive? I'd like to run 4 CXB3590 on a single HLG-320, if it's possible. Thanks.
