that's why i think this ceramic (whole spectrum) concept is going to replace LED as the next big thing. way back when, people had the right idea by combining hps and mh to get more of a balance but was still lacking in much of the spectrum especially uv. leds tried to get by by going with red and blue spectrums but missing the in-betweens. i used the cmh retro white years ago and if they could have made something with higher watttages, it would have taken off years ago. 400w was the biggest available which was good for closet growers but not the big guys.

Uhhhhh, no. LED is here, and it will replace all other forms of lighting.

what lumen per watt are your COBs ttystikk?

i was reading the other day about nano coated leds at 300lumens a watt.

I don't remember, and of course that rating will vary depending on how hard the chips are driven.

56% efficient is the number I remember regarding my COB's performance.

Anyone see there was a proposition to limit the THC for rec to 16% in CO? Talk about reintroducing the black market. It won't pass though.

it wouldn't surprise me if there is a push to limit rec sales on concentrates. some of these 80% thc vape oils/waxes/ etc are way too strong for newbs.

but as you guys kinda mentioned, pandora's box has been opened and it's going to be hard to put her back in.

@firsttimeARE : you still coming out this way??

I have 2 of the 3 I started survive. Ill most some pictures of those 2 later.

The girl scout cookie haze I put screens over two of then last night. The other one had a set back.

Getting light green tips again like I was getting on my Archive gear. Seems to have stopped with higher feeds.

I set feeds to 670 (1.34EC) last week and gave them fresh reservoirs last night and set them to around 650. Before I changed they had fallen down to 400 (0.8EC)

My tap is 90 so thats only .6EC feed.

Does your reservoir feed levels drop daily? Not sure how others do it. But I fill a res and let plant eat up and feed drops continually and once it rises that tells me the plant has used everyhing it wants to and is just drinking water now which is why the feed level is rising.

It sounds like others feed a higher rate and the feed rises as the plant drink/eat and they top off with fresh water to bring the nutrient level back to what it was.

it did when i was doing dwc/rdwc. i did it both ways. either topping off with water and letting EC constantly drop or top off with nutes and try to keep EC constant. i liked the top with just water personally. seemed like they liked the mix of heavy and light feedings throughout the life of the res. that first day of a new res and nutes seemed like they would feed alot.

now i'm drain to waste hempy buckets so feed is constant for the whole week. and pH is super stable too which is nice to not have to mess with all the time

I never have my dwc system over 700ppm. Usually between 500-600 and that with the 150-200ppm from my tap.

I had them at 4-500ppm and was getting pale green tips.

People have told me its overfert yet feed levels drop.

So i figured maybe I was feeding too little.

In flower im at 500-600ppm. Some reason under the hps I get feed rises if I go above that.

Took pics last night but was too busy to upload. Will put them up tonight. Maybe someone can guide me on what is happening. Looks like a copper def. from pictures I see of copper def.

I was told it was overferts but the feed level is dropping. Set 600ppm Sunday night and Monday night it was 520ppm.
