Advice on DWC and RDWC.
CapeGrowsstarted grow question 3 years ago
Hi there,
Any advice on growing in RDWC system?
How often do you flush the whole system?
What percentage of water change do you find sufficient?
Has anyone done autos in a RDWC system before and what advice do you have?
Thank you! 🙏

Hi there. Your on my favourite grow method. I usually let the reservoir run for 10 days. About 12 to 6 hours before a change I add some florakleen to the stem and let that run around until I dump for res for fresh. Every other change so every 20 days I empty the res and half fill it and add florakleen and let in run through the system for 6 hours, then I put fresh nutes again. I like keeping my system fairly full so I would either top up with water or nutes depending on what Ec reading I got. You want to be running at ph between 5.5 and 6.5 and you won't need to feed heavy on an auto. Increase ec 0.2 to 0.3 every change until you hit an Ec of about 1.3 and thats probably the most the plants will take.

Check your ec at the same time every day. I found when the lights go off ec will slowly go up and lights on it will go back down. You want to feed her so that the ec slightly drops or stays the same each day. if its going up she is drinking more then eating and you should lower the levels. its best to change the water every 10 days or you can get a nutrient imbalance. Be mindful of how the rdwc system flows. roots will clog small tubing.

Starting seedlings, which is the best route? Please help!Should I start my seedling right into the medium (Roots organic original potting soil which I have heard can be a little hot for seedlings) or should I start with Rock-wool first and then transfer the auto into the medium. Thank you!Setup. Strain - Autoflowering

Slow release organic nutes feeding! Please help!I am planning on using slow release organic nutes that recommend amending around every 20-25 days. The coco I have should carry the plant 20-25 days also. Should I only feed the full recommendation once and then split it in half to allow my auto flowers to flush the last 2 weeks?Setup.

Autoflower cicle 24/00 our 20/04Good Morning. I have a big doubt about the autoflower light schedule. in the state of vega I can maintain a 24/00 light cycle like this until the end of the flora. or the 20/12 bara both? because I want to remove as much of the strain that would be a magnum from budhha seeds. 27lSetup.

Weird Autos (RQS NLA, same strain) still vegging day 50. Only some preflower, but nice plants. WHAT would YOU do?!This is the most unpredictable auto flowers I've ever had. It will be 50 days soon and only preflower on one plant. Ive used a 12/12 light schedule on autos before. Should I try this on these plants? If, so keep it 12/12 untill the end? No turning back to 20/4 when they go?5 years ago

Dutch Pro Nutrition AmountsNew to Dutch Pro nutrients and Im loosing my mind!
1. When week 3 begin I shouldn’t use Grow A/B no longer?
2. The chart says for bloom 250-350ml A/B per 100 L
I use 20L means 300/5= 75ml
Thing is does it 75ml each or both?!Setup. Strain - Autoflowering
