I have seen a lot on here about Platinum p300's but very little on the higher output units so I thought I would share. I am nearing completion of my first grow and early on decided to try to go all out on it. I am using a 5' X 5' grow tent with 2-Platinum p900 lights, running RDWC with 6 pots and a 10 gal res. This gives me about 100L of water, all pots and the res have air stones. I initially started with 6 plants but lost one part way through to my own newby mistake but have recovered and all is well. The girls are a strong auto sativa and at Day 66 are pushing 4-4 1/2 feet tall with me doing all I can to hold them down. The largest issue I have had with the p900's has been weight, I has to reinforce my tent just a bit as I was forced to rearrange the lights.As I have been fighting such height issues I have had to move them a lot because I am keeping them VERY close to the plants to keep them from stretch as much as possible, close enough that I have burned a lot of leaf tips in the process. As you can see in the pics though that has not slowed things down much at all and it has made the colas huge.
At this point I have to give the p900's a resounding vote of approval. They are well made and have done a great jos growing me some wonderful and sticky new girls the first time out of the gate.
