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...

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...

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...

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...

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

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...

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?

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

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

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...

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...

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...

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

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

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...

No, this cannot be accomplished for $300-400 CAD for 4x4 tent. Telling you as canuck who built his own COBs (Vero 27 gen3) from parts. You need at a very minimum 480 watts of COBs to achieve 30 watt/sq ft. Usually 40-50 watt/sq. ft is what recommended, so more like 650-800 watts is what...

So concensus is to match the strips/cobs on same driver so they have same current ratings? And then use CC driver that suites? I never used constant voltage drivers before but everywhere online says they only work great under certain conditions

Well, after reading some more I realized my choice of driver is poor. Should have went with HLG-240H-C1750 which would have served better.

Already using this setup below for 1.5 months with great success. Now due to absence of double row strips looking to replace one double row with two single row strips.

This is what I'm trying to accomplish, will this work? Thanks
