looking good??

i am seeing a little "black" things on the new leaves, do you guys see it too?, and well i changed the light, its a 70W HPS

Not sure about the spots but my first thoughts are, if you are going to grow in that cabinet,have you made arrangements for ventilation?? Only reason i say this is my cab if preety much identical to yours, and i needed to add some in /out fans just for circulation and then worry about any heat issues( maybe not soo bad with a 70w hps but if you upgrade( and you might want to) it will be heat in the 90's for sure. I can keep mine at about 78-80 with lights on but that's after cutting holes for fans. Just my thoughts, if its' workin for you keep up the good work.

thanks for the advices solanero, well i forgot one picture lol, the vent, its quiet good inside i must say (speaking of temperature). for now i cant upgrade for money reasons, and the space isnt too big (like 55x45 CM)....

Right on. Funny our set up is identical except i took out that shelf that you have your plants on. Is there another 3.5-4 ft. underneath that shelf ?? If so yep we have same cab. Same situation too, i started of with cfl's then a 150 hps then a 400 hps , when it starts getting fun you don't mind spendin a little money to keep your plants happy. anyway good luck
