rock wool

So, I'm new to the hydroponics game, I grew in coco for a while and handfed everything and just recently we completely switched to 4x4 fill and drain tables. Still getting the hang of it tbh but I think I'm close to having it dialed in. I'm concerned that I'm overfeeding the 6x6 hugos that I'm...

Dear gardeners, I am new to the hydroponics and I am very much struggling since the beginning as my plants does not seems to do very well. Growing in the room of 17 x 10 x 7ft, Ebb&flow system, 4 trays, rockwool cubes with clones planted into rockwool slabs, 600W HPS hanging around 25inch above...

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...

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...

Ok so like the title says it's been 17 days since I took my cuttings and I still don't see any roots. Just for background I started with pre soaked Rockwool cubes and my cuttings were dipped in cloning gel. First few days I sprayed em daily and kept up the humidity in the dome , vents closed...

Hey guys just looking for some advice and info. i just completely changed growing style from hps and general hydroponics to LED and Canna newts equipment/newts/style Rockwool cubes in 2 gallon bags Growers choice 720 LEDs 3x3 tray with 40 gal res flood and drain recirculating water is soft...

How many days do you guys wait to feed again after doing the initial soaking of the rockwool cubes? Ive heard to wait about 10 to 14 days till you feed after you soak your cubes but i would like to hear what everyone else thinks.

Hey everyone, I hope this will give a nice idea to every grower that germinates in rock wool. If you let the cubs sit on the floor or in water the drainage would be much worst and u will not have the same benefit that you get with early air pruning. This results in more roots and more lateral...

Hi there, I am currently designing a cannabis grow operation. Right now, I have 1 1000w HPS grow light for every 16 sq ft of grow space, giving each sq ft about 62.5w (close to the ideal 65w/sq ft). LED grow lights aren't really in our budget, but I've heard you can cut the cost by around 3x if...

Hi there I first germinated my seeds on the 8th of Feb, I'm using a COB light and the 2 strains I'm growing are white widow and sweet cheese, I have been feeding them full strength Lucas formula using GH, they have been on full strength nutes for about 3 weeks using this calc...
