Grow Mediums Deep Water Culture Basics - Bubbleponics

Why do most people use rockwool cubes over coco? rockwool stuff is hazardous to breath in and pretty sure it’s generally bad for the environment, if it’s the same stuff used for roof insulation. I personally do not like the idea of it at all.

There is a lot of misinformation out there. I used to think the same way until I looked into it.

This is from GroDan's website:
"Stone wool is a mineral wool made of volcanic rock. Stone wool consists of 5% solid material in the form of stone fibres. The remaining 95% is made up of pores. The basic materials for our stone wool are basalt and limestone. These are melted to form lava in an oven with a temperature of 1,500°C. The lava is then poured over a number of fast-rotating discs. Thanks to the centrifugal force, the drops fly off the discs and lengthen to form fibres. The process can be compared with candy floss being made at a fair. The fibres are then compressed to form a sturdy mass, from which the slabs and blocks are then cut."

Here is a link to an MSDS registered for rockwool. It could cause irritation if you breathed in enough dust and I would not want to get it in my eyes of course the same could be said about my garden soil!

Yo I take it back about the advanced nutrients telling you to use too much, as it does say on the bottles for Micro, Grow and bloom to use 1ml per litre for seedling which seems about right.

I managed to do some damages to my little seedling moving pebbles about, it was really leggy so I tried bending it down under pebbles and almost killed it, instead of waiting to see if it recovers I took a cutting of a photoperiod plant ‘Grandady purple’ to see if that works. I got space for two plants after my auto is done and I have been vegging this gdp so yeah figured I should grow another photoperiod but never cloned before, If it doesn’t work I may find an outdoor spot for the gdp plant and get some auto seeds in and try one in the dwc and one next to it in coco in an autopot and see how they do.

I stuck a dome over the top to keep the humidity up. The cutting is in ecothrive coco, and the pot is sitting just above the water so the bubbles are wetting the pot.
Is this about right?

There’s a mars2 400 with just the red light on the side and a autoCOB I recently got on top. The mars was the main light I had on the NQ up until a couple of weeks ago but with the arrival of the COB I thought I’d put it on the side with just the red/bloom light on. I thought the autoNQ was nearly done but the COB seems to have kickstarted a load of new bud growth, loads more new big white hairs sticking out and buds getting fatter. It’s only In a 8.5 litre pot so wasn’t expecting it to be this big. I had intended on doing a soil grow using biobizz in autopots being newbie, then learned this wasn’t a good idea so just top watered. When it’s done il take out the mars and just use the cob until perhaps flowering.

The autonightqueen is overshadowing the cutting in the DWC but not much I can do about that. Got about 10litres of water in there bubbling with silver bullet roots, the advanced nutrients micro grow and bloom and their silicon to a ec of 0.6.

With just one bucket, how do you empty it with a big plant in there? I’d like to empty it once a week and put I. Fresh nutrients to keep it clean. My pot came with no instructions. Do you use the pipe on the side?

I pick the netpot and plant out of the bucket, place it in another empty bucket while I empty, clean, and refill the growing bucket.

As far as AN dosages go... I grow trees in single buckets (4.5ft, 8-11oz) using a four gallon water level and 24ml of the 3 part pH Perfect. Way less then they recommend.

Oh yeah....I forgot to mention.. I use AutoCobs for my lighting. They outperform my HPS and my Mars II 1200.

Ask @BigSm0 how he can up your lighting game.

I’m rocking a cob from him, my mars is now hanging horizontally.

I got a cutting going in mesh pot in coco with clay pebbles.
I had the water level just below the pot, the bubbles keeping it constantly wet. Is that right? My thinking is the roots grow out when seeking water so they won’t grow out if there constantly wet? I have lifted the pot up a few inches to see if this helps.was even considering taken the pot out to let it dry out.
Also separate unrelated question but when I change the nutirent solution that has silver bullet roots in, would it be bad to put it on plants in the garden? Does silver bullet roots kill all microbes or just bad ones?

Is the clone rooted? Top feed until the roots are 1" to 2" into the reservoir. Then it is no longer needed. This is what my nursery looked like when I was doing DWC.

I guess it has rooted or has started to as it’s still alive the leaves haven’t wilted, so guessing it has rooted but didn’t want to poke around the stem and look in case I broke them. I shouldn’t have thought I would need to top feed as the medium is damp just from the spray of the bubbles. It’s absorbed it up through to the top of the pot I can see that. Or should I have not turned the bubbles on yet?

Only giving it 18 hours light though which isn’t ideal but got an auto in there, 24 maybe fine from the start but increasing the light hours to 24 during flowering doesn’t seem right/ unnatural

18/6 is ideal for so many reasons. I have grown autos with 24/0, 20/4 and 18/6 The best yield per watt comes with the 18/6. The 20/4 was a little bit bigger yield but the price of electricity used out weighed the benefit. 24/0 was lower yield and quality.

Top feeding directs the roots down into the reservoir faster as they follow the water down into it. Most cuttings need to be rooted before you move them to the reservoir? But if this works for you then perfect. It just goes to show that there is more than a hundred ways to do this
