rockwool

Recently switched to 4" (10 cm) Grodan cubes to run my SOG from clone to harvest. Method: 1. Place cuttings in root riot cubes until roots coming out (5-7 days) 2. Place root riots into the rockwool cubes, veg until roots come out of the rockwool (4 days) 3. Place rockwool cubes straight...

Howdy! I have been meaning to commit to a grow journal since my last one failed to make it beyond the introduction, and with the new year being 9 days behind us, I feel like its the perfect time to be fashionably late. I expect this year to be exciting and tragically short, with more plans and...

I have been growing with T5 in veg and HPS on bloom for over a decade. i just switched to LEDs... ( GC e420ROI & fluence SPYDRx in Veg ) and GC e4720ROI in bloom... I used to use the 5/10 with GH flora series in veg under T5, the bump it up to the full strength 8/16 in bloom under HPS. never...

Hey folks, Configuring a new little flood/drain table in a 2x4 tent. This will be for 2-4 plants, and likely use a screen to even out the canopy, scrog style, as I don't have a ton of height (the tent is only 6'). I'm debating between the following two approaches: 1) 5" net pots with...

These seedlings were doing fine, then they just started curling up on me one day. I’ve tried giving less water, it hasn’t seemed to change anything. They’re on Athena blended. I feed them 2ml A & 2ml B (200ppm, PH5.8 as they are in week three. They seem stunted to me as well maybe? The most...

Almost done, day 57 from flip. Dropped my EC to .6, let my PH stabilize around 5.6. WW has fall colors, cloudy trichs all over the top colas. Lower half could use a little extra time. BB (Left) is directly infront of the fan, and shes suffered for it, shes got alot of clear and amber going on...

Wrapping up my first grow. Got some fading going on with the white widow, I think shes about 1-2 weeks from harvest. Blueberry is probably closer to 3 weeks. I am kind of supprised the WW matured quicker since it shows more Sativa traits, but here we are. The purples coming out of the WW may not...

Got some burnt leaves late in my first grow and I would like to discuss what I have done wrong and what I can do better. My set up: 4x4x7 gorilla grow tent w/ 2 GLS 300 LED lights. 4in intake cloudline w/ 6in cloudline exaust using advanced controller. Flood and drain w/ rockwool, coco mat, and...

I don’t have an ac or dehumidifier so I don’t have the best environment. And it’s been pretty hot outside. First time trying hydroponics so any feed back and suggestions would be awesome I’m trying to learn . Day 21 flower . I feed them the full line up from advanced nutrients and elite 91 30ml...

I have 1 White Widow and 2 Blueberry in rockwool. They are sharing the same ebb and flow tray, using Jacks 321 nutes, under 2 GLS 300 LED lights at about 70% strength. Watered 3 times a day, at 1 hour, 6 hours, and 11 hours into the 12/12 day cycle. Pool shock for sterility and added h2o2 in the...

What a fucking week it has been... I started flower on my first grow this past monday (7/26/21) 2 blueberry and 1 white widow in ebb and flow under GLS 300 LED lights w/ Jacks bloom formula and 1 airstone in a 17 gallon reservoir (RO water) I made 2 huge rookie mistakes. I over watered the...

I am a noob starting my first ever indoor hydroponic tent grow but have had real difficulty getting my ladies past seedling stage before they suffer from damping off or root rot. I am using rockwool starter cubes and intend to transfer them to larger cubes and then use a recycled drip system...

First grow, doing flood and drain with rockwool, jacks (clone for seedlings, RO for veg, bloom first 2 weeks of flower, 3-2-1 for the majority of flower, and finishing with finish) Going to cover the table with panda film and line the bottom with coco mat. Veg light is HLG 100 4k, going to...

Ok so Ive got a moderate amount of experience cloning but I get mixed success when it comes to getting them to develop roots and ready for transfer. I'm going to attach photos in case it helps but I'm a little unsure wether or not my clones have started to root. Ive been using a humid dome for...

oh hope someone can help me come up with a solution quickly for this issue.. I am using rolling benches and drain to waste. -12 inches off the ground (these are low benches. not much room under) each bench slides about 8 inches to each side, so location of flood drain/trays are moving.. I...

What ec should my soaking solution be for freshly rooted cuttings? My tapwater ec is at 650 so how much nutrients do I have to add? I read something about 800ec so i have to add 800 in nutrients or only 150? thanks

Hey everyone, been really enjoying reading all the great advice on here so far ! I am 3 days into seed germination now and not seeing anything sprouting so wanted to post and see what you all think? PH balanced water with lemon juice - reduced ph as it was high (around 8). Poured on to rockwool...

Hey, so I have a 4 x 8 table i plan on setting up with rockwool. I cant find an answer really anywhere. What should I line the table with? Coco Mat has seem like the best choice. Would I still need a drop ceiling plastic grid type thing to keep it off the bottom of the table? Or plastic plastic...
