Hello everyone, which Grodan slab do you use for a drip system, and why? I'm using GT Master now, but considering a change towards Vital. Any thought? There are 3 options: GRODAN PRESTIGE vs. GRODAN GT MASTER vs. GRODAN VITAL ? Thanks, cheers!

beautiful

got it, thanks!!!

So much information in this thread! This is my first attempt to cross-polinate. My males are small clones, still have their "father" in veg. They are in a 10x10cm rockwool cube. I was thinking instead of cutting and putting the stems into water, I'll just lay them down horizontally over a baking...

How about the control tank size at this RDWC? 2000 liters would do the job if I have 900ish Liters in the pipes? Thanks

I called one of the shop, that's what they said. The brown one, 5 meter long, 160 mm diameters. 30 usd. I don't really want to argue on that :D

I just checked. PVC KG drainage pipe (which can even hold pressure underground) is 30 USD for a 5 meter (16.4 foot) long piece, 160 mm diameter (6.3 inch). I'll need 16 pieces (for 200 plants), so it's 480 USD total. I'm not sure how to make it cheaper with separate totes or buckets, plus the...

Okey, completely makes sense. That means I need a big drain hole (10 cm diameter) which I have to check time to time. If there are plenty of roots inside, just prune it? I draw it, this could work? Dissolved Oxigen is a great point, wanted to ask that too, just forgot. The water falls to the...

Thank you Mister, that's well explained. Your setup looks neat! The idea to keep the water level high is because of exactly what you said: if a pump fails, there are still backup nutes for them in the pipe. Plus the roots are very well marinated, no need 200 sprayer heads. I personally like coco...

This is exactly the pipe I'm concerning about. They sell it here in 5 meters lenght pieces for like 20 bucks. How about the control tank size?

You mean Tote boxes like this? https://www.bigdug.co.uk/mega-deals-c411/bigdug-tote-box-mega-deal-p17041/s39131?cid=GBP If so, it would costs way more and I can't imagine the water consuption :lol:

Ladies and Gentlemen, I have a dilemma before I invest shit load of money, so I would like to ask your opinions about it. I would like to build a recirculating DWC system in a big scale. Instead of buckets, I would use long discharge pipes. Each pipe would be 410 cm (13.5 feet) long, and there...
