pH and PPM meter (look for an option to display EC as well as ppm, helps if you are looking at an off brand meter) are necessary for DWC.
Have the ph meter. Will look for a PPM and EC Metrr. Any recommendations?
You will want a submersible thermometer to monitor reservoir temps.
Have wireless thermometers from my smoker I thought I would try
What grow media are you using? Hydroton?
Already have the hydroton
Do you have your timers all set for flower photo-period?
Have the timers
How about small fans for moving air inside the tent to thicken up the branches and help to prevent mold?
Have two fans might pick up a third
Be sure to pick up some patience as well, I have found that to help the most so far ha-ha.
I need lots of that. Haha
Pick up a graduated pyrex beaker/flask for measuring liquid nutes if you don't have one - eyeballing is a bad place to be.
Eyedroppers or pipettes for pH up and down, if you want to get fancy -- its fairly easy to use too much especially when EC is low and the water isn't well buffered
I have pipette and syringes
I have a small dehumidifier for flower, its nice for keeping the RH around 40-45% and only cost about 25 bucks
Don't expect humidity to be a problem here. Might even be too dry.
The fun purchases come later if you don't have them already - but mason jars, microscopes/jewelers loops, bubble bags (or equivalent or the trimmings) , trimming sheers -- things that make you salivate watching your plant finish up.
I have mason jars. Is a dozen quart size enuf. Lol.
Will order up some jewellers loops, trimming sheers, and bubble bags
I sure appreciate the suggestions. Anything else?
