I have a 2 plant recirculating DWC. DWC Recirculating 2- 5 gallon buckets w/30G tote reservoir 1/10 Water Chiller - Chilled to 66 Degrees 400w HPS 4x4 Tent 400 CFM Active Air w/ 400 CFM Phresh Filter I was considering upgrading to a 600w light or AN Additives as I have only used base nutrients. What would you purchase?
Lights without a doubt. I guarantee you would see a much larger benefit from going up an additional 200w than from using AN.
I would buy the stuff to put together a good solid organic soil mix.Mjmarijuana is nature's way of saying high!
