Absolutely! We just witnessed Curso pull
1.75 pounds from one plant using our 2 x P450 lights in a 4x4 tent. Keep in mind that the total wattage draw was only 550-ish watts! Totally do-able.
..and yes.. this site is an incredible resource for the community and especially when we all work together to help advance the technology. It's really amazing how far we've come in such a relatively short time with LED technology. Much does depend on purchasing the right equipment for the job, though.. and this is why we are so adamant about choosing your lighting so carefully. It's not about bashing anyone or any thing.. it's just a compare and contrast that if you use a lighting source that isn't putting out as complete of a spectrum or as high of a PAR value for the watts consumed, your grow is going to suffer.. and end up costing you more money that you ever saved with those cheaper lights. Whether you go with our lights or another premium brand.. it just pays to do the job right the first time.
We honestly.. and from the heart.. want everyone to succeed in everything that they do.. make beautiful, beautiful flowers.. and be good to each other while doing it. However we can help people succeed whether by words or by lights, we'll take it.
