Not true. Ive had great success and never used any of cannas other stuff. I have used other minor additions but you dont even say what kind of lights you have. You need to understand that nutrients are not the fuel/food for the plants, the lights are nutrients. The nutrients are just the vitamins.
Someone else could tell you. Tbone on grasscity and others is very knowledgeable on these areas I do know you might wanna watch out for being screwed on fake boards that look exactly the same but dont have the ppfd that the true Samsung does. That don't mean that isn't a good or great deal I...
I looked into spacing my 260 W away from each other but the heat sink would have to be cut in half or get a completely different heatsink I didn't want to do it so I just did it this way 30" x 30" frame 560 W total
Yes. From seed.

The cobs came from Timbergrowlights and the quantum board came from HGL.
Here's what I have a cob/ quantum board system on one 30"x30" frame. I also have a 4 x 4 tent The Cobs are 3500 K and the quantum board is 3000 K both together is a total of 560 W. I also have two more quantum boards outside lighting but not needed much.
Exactly what im thinking. Just like another post somewhere about drying at 80degrees. I think some are right when they say there are people that are purposely trying to jack up and ruin people's grow just for kicks and giggles.
Im not saying im any Genius or definitely not a damn know it all but watch this video and tell me this guy seems smart. I watched 10 to 20 sec in and laughed my ass off.
