im planning to have a hyroponics setup but i need to understand some things before i jump into the process. im planning to make 2 "bubble buckets" based on the sticky and was wondering how many seeds go into the each mesh bucket and what light do you think would be best suitable(400hps or 600 hps?? is maintaining co2 levels critical in only 2 plants? i plan on gettin tds and ph sensors for each bucket and getting everything needed but im concerned mostly in the care and attention its gonna need. im pretty busy most of the day and wouldnt be able to attend the girls when the ph levels drop or rise in any given situation. how much attention do you think would be needed to tend to these plants? and how often to you have to drain and refill with new water and nutrients? whats RO and ANand hyrdro nutes?? whats the best nutrients i can use to produce the best crops and the most amount? all input is greatly apprecieated. thanks in advance.
