Growing with rockwool as a medium

NYCD x Ms Universe on Bigblocks. Canna Flores A + B or Coco A + B (they both work fine for me).

WOW! Awesome results. How long did you veg?

I wasn't sure on the big blocks, I'm using the small cubes in a plant pot. What made you decide to use those as opposed to what I used or even the grodan slabs?

Thank you JDMase!
The plants vegged for about three weeks. I chose the big blocks over slabs because they are easier to prepare (lay 'm on the floor and go) because of mobility and since i water by hand i like a bigger medium. This is my first run on big blocks and i couldn't be happier. There is absolutely no more forgiving medium i have run across and i neglected the plants big time.

Amazing! Your picthres have disappeared for some reason though!? If possibly upload them to RIU so I can show them to my disbelieving friends that think rock wool is crappy!? Thanks!

They disappeared because i got banned and they deleted my acount. Here are some pictures from the same plants a few days before i harvested them.

















And here is a picture of my current round:

I tossed about a 100 gallon water in the bucket, Ec 1.6 and pH 5.3. Strain: clones from Soma's NYCD x Ms. Universe.

I upgraded to a ebb and flow system with two plunger pumps and a water reservoir of 200 liters. I pump the water in the leak tray until the rock-wool big blocks are flooded and pump the water out again.



The cubes suck up as much water as they can retain, so i only have to flood a few times a week.

Looks like a pretty good system! I recently invested in a gravity drip feed system. My plants liked the regularity but it needs to be topped up as I realised it only gives a tiny 1.2 litres PER DAY. Definitely not enough. Ah well, it got me by whilst I was away!

What was the brand you went for? Was it expensive?

If you can get away from it that is definitely a plus, but i have noticed too that feeding the blocks from the top with a drip feed system is not ideal.

The ebb and flow system i use is not at all expensive, what you need is a leak tray that is waterproof, a water-reservoir and two plunger pumps. One to pump the water in the leak tray and the other to pump it back into the water-tank (which can be set with timers too). Make sure you flood until the blocks are under water, so they get completely saturated, which is a huge advantage of this system compared to drip feeding in my opinion.

Sensi's Super Skunk cuttings on rock-wool (mapito).





The nutriment is GHE Floranova and they are one week into flowering.

I start with 2.5" rockwool for seedling and finish it in 4" rockwool

I find that rockwool is a very easy medium to use

I have no fertilizer brand loyalty, I used whatever is available (I mix my own ratio). My set-up is a hybrid hydro.

Top feeding ANY rockwool from the top in a drain to waste setup IS IDEAL. And much more forgiving than a flood and drain recirculating system. You got it backwards.
 
Is it a bit late to write on this thread lol I’m a new grower aswell and I love these Rockwool cubes , I just switched over to the 4x4 cubes stacked on top of the 6x6 and stacked again ... lol but so far I only water about 2-3 times a week which is awsome! Anyone else still on this thread ?
