I looked on ebay and TDS meter is cheap and I have kinda blindly just going by the directions on the bottle so I will pick one up in the next few days. My latest clones are in the veg bucket now for almost 2 weeks and thier growth is now picking up (full veg stage), the ph was 6 to 6,5 or yellow on the test bottle so I added a 1/4 eye dropper and it is now 5.5 to 6 more tan color,,,,,,,, what do you think maybe spring for a electric ph meter too,,,lol.
I have been using six seperate 20lt buckets during flowering and some of the kits on ebay are really simaler to the rubbermaid tote veg bucket I use but the base is bigger then mine which holds 20lt but still has 1 pump and six 4" buckets so I was thinking if I put a bigger rubbermaid tote under my exsisting lid and extend the pump to the bottom it would be much easier to moniter and maintain 1 big tote of water instead of 6 individual 20lt buckets while flowering under the 430watt HPS. How close can the clones be kept if I usually start flowering at 6 nodes? Centre to centre my pots in the rubbermaid tote are about 6" tops is this too close together?
