    FB24B Strip build, everything ok?

    That is a wrong statement. At 1.67A per one FB24B will get aluminium 2" channel not much warmer than 40C. That is a slightly higher than body temperature. Touch yourself and tell me if it feels hot? I can run my FB24B at up to 2.5A each and they never get above 60 C, and that is not hot, not to...

    Samsung FB24B Build help

    You can really drive them at what you like, thats the whole point. Right now each driver set at 50% (wired potentiometer), so about half the current of 2.5A each strip. Actually my second driver has two single row (FB22B 5000k) and 1 double row (FB24B 3000k) so the current split equally between...

    Samsung FB24B Build help

    This the 500 watt Summy beast I built, I'm extremely happy with it. Designed for 2x4 tent and it will deliver. Very low profile at just 2" thick. Blows my Vero 27 gen3 COBs out of water by producing less heat using same wattage as well as way better light distribution and less shading. Also my...

    Samsung FB24B Build help

    I run 2 fb24b strips on HLG-240H-48B in parallel (that is 5 A driver, so 2.5 A each), two fixtures like that for 2x4 for 500 watt total for that area. I figured I can always dim. At that current (2.5A each) aluminum channel does gets slightly warm, like may be 50-60c but these strips can handle...

    question - 500 Watt true colour led from Yuji LED ($500)

    Just 1 Sumsung F-series 4 foot strip (double row) pushing 19,000 lumens according to datasheet. So 23,000 lumens from 500 watt = horrible efficiency

    Soil Test results are in for No-Till any recommendations for improvement?

    Good advice about ph, you see my tap water is around 8, or slightly higher, so using tap water (I SIP, soil is always saturated, they drink as much as they like) eventually bumped up my pH possibly. I will use some gypsum and peat to correct the issue. I agree with you on my pots probably too...

    Soil Test results are in for No-Till any recommendations for improvement?

    My 10 gal no-till pots currently sitting filled to 2/3. I was thinking to top dress it to the top with fresh compost, worm castings, neem meal, crab meal, rice hulls. What also should I add or not to add based on this report?

    Fungus gnats in my soil....

    If you look closely I didn't quote you but JavaCo about neem meal. I have experience with both, just sharing it here with others

    Soil Test results are in for No-Till any recommendations for improvement?

    I see that my phosphorus and potassium almost twice as high, have to make sure I don't add any additional. What also? How come Nitrogen not mentioned

    Soil Test results are in for No-Till any recommendations for improvement?

    Just got soil test report from Logan Labs. Here the little background on this soil. It is exactly a year old now from the date I mixed all ingredients for no-till. 1/3 of all amendments was homemade compost. Soil was cooked for 3 months, then few worms added to each pot for good measure, they...

    Fungus gnats in my soil....

    For some reason top dressing neem meal did nothing for me. What is interesting is neem meal gets white and fuzzy after watering and guess what the fuzz is, right fungus. Fungus gnats were right at it crawling and feeding as usual. Besides predatory mites, what really worked for me was...

    Fungus gnats in my soil....

    I tried everything to get rid of them. And nothing really worked until I introduced predatory mites that feed on fungus gnats larvae. Mites will establish themselves in soil and you will never have same issue again. Try adding neem oil to your watering schedule, about every second or third...

    Fungus gnats in my soil....

    For me experience was worse than spider mites. If you have couple flyers around not a big deal, but in big numbers and untreated they will devastate your plants after some time

    Fungus gnats in my soil....

    Two words: Hypoaspis miles. 1000 of these soldiers cost just $17. They will not just take care of your gnats they will keep them at bay for months if not years to come

    would it be possible

    These prices are far away from reality for Canadian consumers. You listing US sites and products, it cost more here. F-series strips $36 for 4' single strip (50 watt) or $65 for double row strips, which are 100 watt (Best value). So you looking at 7-8 double row strips, or approximately $450...
