If I put a 400 watt light next to a 600 watt light do I have the same lumens and penetration as a single 1000 watt light? I need a 1000 watt but don't want to spend the money if my 400 & 600 together will do the same job. I have my doubts though, thats why I'm asking for help. It seems like it...

I have heard to use one quarter strength and other things people have suggested. I was hoping that someone familiar with Jacks could tell me. I've been having problems with both yellowing and what appears to be burning on the tips. I'm confused because I just got a PPM meter and it seems that I...

Hi there, I have four random plants planted in a storage container in hydroton and lava rock. They are top fed and drain freely to another storage container below it. I'm 21 days into flowering and the three other plants are doing great except this one. The upper leaves are evenly turning...

HHi there, My plants are too big and heavy for me to be moving them around any more, I'm disabled and it's a heck of a lot easier when they are little. My question is..At some point do you just say screw it and stop treating them with neem or whatever? I'm growing in a mylar tent so I don't...

Hi there, I have a 4x2x5 tall mylar lined grow tent with 150 watt hps and two 200 watt equivelant 2700k CFL's. Do you think this enough light? Should I bother with the two cfl's or just run the HPS 150 watt?

I don't understand what optimum is. I'm going to purchase a ppm/tds meter in hopes of being more accurate. Please help!:!: Thanks!

I'm going to try these based on what I have heard on this site, I'm interested to hear users opinions because I'm sure a good fertilizer regiment shouldn't cost you as much as your lights do. I'm tired of paying for all kinds of s--t. Please talk to me! Thanks so much!
