rockwool

Hello all. I’m looking for some input on a system I just built from spare parts. Im fairly new to hydro so all tips are appreciated. I have 12 5gal buckets with 4” net pots that I’ve cut rock wool cubes to fit in. The net pots only hang about 4” down into the buckets. So far it seems good, I...

I’m wondering if I can take my clone in a rockwool cube and place it right in the 3 gallon pot. The 3 gallon will be its final container. I was going to put in a solo cup first then move but was wondering if I can skip that step?

Hey Hydro team, I have been having some serious trouble cloning recently, and it has led me to experiment with a few different cloners. I use rockwool by default, but recently built an areoponic cloner (H2O2, no nutes) with 1/30 success rate. My rockwool cloning is not much better, I attempt to...

For people that have used Grodan products or other types of rock/mineral wool, what issues have you come across?

First Time Grower This is the 8th day since I planted seed . they are tangerine dream autos. They don’t seem to have made any progress over the past 3 days . I think I might have overwatered them . Been giving them about 100-200ml of PH balanced water at 5.7 twice a day. No Nutrients Yet...

I'm finding it better then soil/less mix, coco, DWC, ect.. No mess, no root rot; no problem, for now. P.S I forgot to buy a 2.5 gallon bucket for the top so I had to improvise.

Hello, these plants had a good veg. Although I think I was over watering them but they still looked good. I should add this is the first time using Rockwool, I only have done coco before this. So then I flipped it into week 6 of veg The next couple days all the plants were just wilting. I...

I've not grown for a couple of years because reasons, and I'm wanting to use an automated configuration with 6" rockwool blocks. I don't have a good handle on watering amounts. If I want to have a reservoir for a week, what size of reservoir tank should I calculate under 1000 watt HPS , I'm...

Hi, New to growing. Any advise on when I should put these from here under my T5 into baskets. Thanks

I am having an issue with trying to get roots from my rockwool cubes. I took 4 cuttings (2 white widow, 2 afghani #1) and followed a step by step tutorial I found in another site. This is day 7 and no sign of roots. In anticipation of the clones failing I had ordered an oxycloner and it...

This is the start of my 2nd grow with my CMH light. I have 7 Wedding Cakes, 6 Purple Punchs, 1 Peyote Critical, 1 Blue Gelato 41, and 1 Cheese that have been germinating for 2 days. They have all opened up and I'll be setting them in 1.5x1.5x1.5 rockwool cubes. I will do my best to log my grow...

A friend of mine is curious why he continues to have issues with root rot with his DWC hydroponic setup. He has killed off 6 fem seeds already and now his new crop just began to show leaf drop today and upon closer inspection.. the early stages of root rot with 4 new strains... Here's what...

So I've only ever cloned using rock wool cubes with clones and I grow in dirt. The issue I have always had is when I transplant from clone dome to dirt they always shrivel up to just the main stem then the littlest shoots come out from the base of nodes. I am using no till soil that has actually...

I have 6-inch Grodan blocks with FloraFlex Caps. Can I use just 1 line per plant vs. 2 per plant like I see in their videos?

I'm having problems with my seedlings dying after they sprout in rockwool cubes. I have had a few successful grows in my basement grow room (it's finished, clean, and dry), but I've been having some problems my last three attempts. I start my seeds in rockwool cubes dipped in pH 5.5 bottled...

I need some suggestions. I have 11 liter bato buckets, I ran them with 2 to 3 inches of clay pebbles in the bottom and the rest filled with coco. I decided to give running 6x6x6 rockwool cubes a try, i am going to stick them in the bato buckets. I will probably keep the 2 to 3 inches of...

Hey Guys.... Im planning on replanting these later this afternoon, should I put them in RockWool first till they have developed their first leaves or Can I Place them Strait into my DWC Hydro System With Expanded Clay pellets? Thanks guys PS this is my first grow! Any tips and Criticism welcome!

So I'm using the most basic setup... Rockwool cubes water and humidity try/dome. I took the cuts about 7 days ago now, they're all mostly still looking pretty good, but I don't think they've rooted yet, or have just barely started. My cubes are getting a bit dry though and I'm wondering if...
