onthedl & illegal smile, you guys really seem to know your stuff. This is my first attempt at indoor growing. Me and my pops have grown outdoors at the cottage for 4 seasons now. Considering these plants get minimal attention, we do pretty good. Biggest problem we usually have is the fukin deer eating our buds. Anyways, I just finished building my grow room and my DWC system and I would like you guys to critique my setup.
My grow room is a spare bedroom, it measures 15'x9'x8' I built a partition wall so my grow space is 8'x9'x8' All the walls in the grow space have been covered with mylar. A 440cfm inline fan draws air threw a Can-75 carbon filter and vents out a window which has been blanked off with plywood. I also have a 190cfm inline fan to cool my single 1000w MH/HPS, obviously using a air cooled reflector. The cooling fan draws air from another empty bedroom and vents out the same window the vent fan does. Not using any intake fans, all fresh air comes in from under/around the door. This setup keeps the room under negative pressure so hopefully my house won't reek and the neighbors shouldn't smell anything either.
My DWC system consists 6, 5gal buckets connected to a central res. The res has a 18gal and a 30gal rubbermaid tote connected by a float valve. There's 15 shut off valves in total so I can valve out any of the 5gal buckets or the upper res from the lower, should make maintenance/water changes pretty easy. For air I have a 885gph pump. The pump has four outlets which feeds into two aquarium gang valves (2 in, 3 out) so I can shut off the air supply to each bucket. There's a 5" airstone in each bucket.
In all our outdoor grows we started with 10-12" tall clones, but the person we get the clones from got busted for drunk driving, so he's outta action for a while. So I'm starting from seed for the first time. I got the seeds from nirvana, I don't think I will do business with them again cause they are taking forever to sprout. I germed them in rockwool. I soaked the wool in tap water ph'ed to 5.8, shook out the excess water, put them on a plate and cover ed with a glass bowl and stuck them in a cupboard. That was almost two weeks ago. Outta ten seeds, two have sprouted but haven't broke the surface of wool, 5 have cracked and the tap roots are just starting to emerge and 3 haven't even cracked. I don't have a/c in my house so its been bout 85f inside for the past two weeks, figured thats plenty warm?
Please tell me what you guys think. I would like to take care of any potential problems before I put my seedlings into the system. Also, for nutes I will be using sensi grow/bloom and I do have a nute meter and ph pen.
