I doubt that a forest has same co2 levels at night and at daytime and same thing with a industrial city in comparison. or am I wrong here? I always IMAGINED that co2 in a forest must be high at night and low in the daytime and a city (people, cars, industy) would have a more even co2 level all...

This is really a thing! I just googled it and people grow with their urine in hydro... I dont want to smell it after forgetting to empty the tank for couple days haha

You always so helpful, your great, Rocket :) Multiple ppl mentioned Coco being close to hydro in terms of quantity and are easy to operate! Thanks to everybody, I will consider all your input!

Thats funny man, I had a nice laugh! I got your point buddy!

Hi, I am growing for many many years, outdoor and had a lot of experience with growing indoor in living organic soils. But now I am at a point where I will set up a room for a friend of mine, and my friend does not want to go the slower Organic soil route, but he wants whatever brings him the...

This sounds super logical to me and I will try this out in a later order for sure! Thanks, a lot of red and a wide blue sound so right to me, everything else is there anyway but only this two specs are driving most photosynthese activity, as far as I know. Nobody suggests any 730 or 390nm, and...

I understand what you are saying, thanks! I think you might be right, I need to try it out myself. now I already placed a sample order but I think I will order later another 1-2 samples with the specs that you and brazzik25 suggested, they both sound super reasonable! people grew great bud under...

So thank you for quick reply and I guess it has been discussed somewhere many times, appreciate your input anyway! I will ask to make 60%-EVO3000k and 40%-5000k301b 225whites (100x5000k+125x3000k), 40x660nm, 23x730nm But @Rocket Soul What other lights produce better flavours? I have the...
