1 Why use a PH meter on a hydroponics setup when they make perfectly good PH (either the liquid kind or the test strips) test kits for aquariums that are highly accurate? 2 After u germinate your seeds and u are using a bucket areoponics setup what do i plant my germinated seeds in? 3 I have a 250 watt and a 400 watt mh unit if i only want to grow 2 plants in bucket aeroponics closet setup which should i use if either? 4 How much yield can i expect from 2 plants give or take?
Hi, I'm no pro but i'm sure i can help you with questions 3&4. 3. Depending on the size of your closet, and how adequately ventilated it is, i would say go with the 400w. More light = more lumens. More lumens = more yield potential. However, you may have heat issues in a small closet. 4. Yield always depends on many factors and growroom conditions etc...A good rule of thumb is 1oz per ft of plant. Hope this helps, peace
