started seeds a week days ago , in paper towels. Old habit. (I grew a little 15 + years ago. stop growing to raise the kids. Kids are grown so time for me to grow.)
System came together ok . but now I need to work on the room. Temps running around 80 to 90 and humidity was hanging around 80 , now 70 after I added a fan to the room.

came up with a nice pump system , used a boat dc pump ,( burge, livewell pump), found at walmart . and a ac/dc converter, make sure it's a 12 volt converter. and a timer from home depo.

right now the seedlings are under 2 100w cfl's, but got to get at least a 400 hps. money is short and got to get a a/c to cool the room so i'd like to build my own light system. I know i can make a nice reflector, but where can I get the lite ballast parts and socket?
anyway , i'll post some pics over the weekend.
rockon696 Reviewed by rockon696 on . ebb and flow I want to set up my first hydro system, but befor i do I want to have everything on paper, ( blueprint) before I start the set-up. The system below is what i'm planning. it's a 11 plant system using 2 liter bottles. I have a few ?'s. 1- What is the best medium for this system? 2-I'm thinking about using clay pebbles, are the clay pebbles fine or should I mix in perlite? 3- If I only use the clay pebbles, how many times a day should I flood the system and for how long? 4- If I would Rating: 5
