I like to elevate my buckets just a few inches above the res. If you get a power outage then no flooding. My res I got from Lowes, it and 4 buckets hold around 20 gallons of water. I need this as at they drink 5+ gallons per day in flowering mode. Also if you set the res outside the tent then the water temp will easier to control if you don't have a chiller.
oh dang thats' then, this is now, too bad she's hermi'n. Found a few nanners, but I'm not chopping her yet. edit* measured from the trellis.
A little update on the drainage system: View attachment 2726098 This time around I used some larger stones to fill the area around the bulkhead drain. Make sure to use stones that are larger than the drain hole (my drain is 3/4"). I placed a piece of the copper into the drain. I covered everything with 2 layers of agricultural weed barrier, similar to this View attachment 2726100 I will be harvesting the plants within a week and examine the root system and will let you know (see) what is going on. Again, no problems this time around with drainage.
You might be right, but it didn't cause any hermi'n last time. Also, I may not need it, I will evaluate the roots after this harvest. I tend to blame the hermi'n on (a) genetics, (b) light leaks, and (c) spectra, but there's definitely other causes (ie. stressors). After I got back from a 10 day hiatus, my wife confessed that she would come home at night and turn the light on to prepare the solution and feed the plant (instead of doing it in the morning like I asked); major nono. Also, the plants are getting too hot, but they are getting too close to the lights; I didn't want them to stretch soo much but that is because I don't have enough blue light in there (I suspect). Sativa stressing under too much red ? maybe. Other plant systems use copper like that in the drain system, but you are correct in suspecting it. If the barrier and rocks work alone, I will stop using it, but if the roots only stop where the copper is, than it would be a benefit (in this system). I will post the results when I get them. *note people, HD's concerns regarding the copper are valid as they could potentially solubilize into the feeding solution causing toxicity to the plants.
Did you read part 2? Its still in progress... same kind of results though Aeroponic model 4Z0 Stoner Experiment #1745188 rev_2.b
@trojangrower I have me and a friend were talking about these DIY systems other day and he was looking for a good how to example and thought this was a good one Sent from my iPhone using Grasscity Forum
