hydroponics

I have done a couple of grows but was fortunate enough not to have any real problems, so identifying issues isn't exactly my strong point. Could anyone tell me what is wrong with my plant, please? I am using an LED light and it is growing in a hydro system. I am struggling to control the...

Hello everyone. I’ve been having some trouble with feeding my plants and understanding the amounts. Can someone help translate the chart provided on growweedeasy to ml?

What's going on everyone! Looking for some help with my ladies! My wedding cake strain just started week 3 of flower this past monday. showing insane signs of yellow leaves, dark and purple sploches on leaves and red/purple stems. Bud sites are growing insanly slow and are yellow on top. Im in...

Hello I am growing for the fist time! I’ve got auto flowing blueberry Cush. things have been fine until now I am growing indoors and two weeks into flowering. Some leaves are going yelllow some have brown tips and a couple brown spots! I gave them some ‘trace elements’ and some nutes but...

Not the greatest pictures but they appear as little green balls

So I have a question for the community. If you had to choose to run an A/C or a reservoir cooler in your grow room which would you choose? Yes I know both would be the best, but let's pretend that you can only choose one. The system is an 4x4 ebb and flow with a 40 gallon rez. All this in a 8x8...

Hi everyone, I wanna ask about ventilation. I am looking for purchasing: 1. 98x48x80 or 8x4x7 grow tent 2. 2 3000w aglex cob leds. 3. 8 inch ventilation system 740 cfm my question is that will I need an ac for the tent for cooling down or the inline fan is enough to take the hot air from the...

I was just wondering if anyone could give me any pointers about the use of cash crop box. I am specifically growing LSD strain. So any tips on that particular weed. i will be growing inside of a closet in a spare bedroom. Any pointers on smell? Or ventilation.;);)​​

The problem: As you can see in the pictures, the plant is generally healthy, but the stem just above the surface appears to be dying. This is the second plant I've grown from this seed and the second time this has happened. The stem above the surface becomes constricted/weak and then darkens in...

Hello growers! First of all, I must say that I am grateful for being a part of such an awesome community! Im really glad I came across this website while doing some research on deep water culture, I found an encyclopedia for growers! That being said, Im a newbie to the hydroponics I already...

I just about have all the supplies to setup my environment, but one big thing I'm unsure of is whether my temperature range will be optimal. I'm putting my 2*4 tent in my semi finished basement. I've been monitoring temps and they have been in the 18-19 C range over the past couple of...

Is it ok to adjust the ph in the reservoir while the plants are in it 5gal dwc? My ph is consistently creeping up between my reservoir change (1 a week). I’m starting to notice a bit of yellowing on some new leaves. I’m using de-gassed tap water with a starting ph of 7 before nutrients...

Hi all :) I'll be setting up a new tent around september once the current grow of 4 auto white widow XXL's finishes. So far, I've settled on the following: - Tent: Green-Qube 1530 (1.5m x 3.0m x 2.2m) - Air filter: RAM Pro Filter rated for 1080m3/hr (250mmx600mm) - Extractor fan: Systemair RVK...

So this is my first grow, many mistakes were made because that's how I learn. I'll make this as short as possible: Sativa 100 liters DWC 2 air pumps 200w light on vegetative stage, after that added 600w HPS. Vegetative stage was 2 month as I couldn't get my hands on the right lamp for flowering...

I am preparing for my first grow but the problem is I travel for work quite a lot for parts of the year. I wanted to try to automate things in the grow process like pH levels, nutrients and water level as well as a camera so i could check up on the plants and see them grow without being there. I...

I've got four plants in a 4 x 4 tent, almost two weeks into flower. One of the plants has some lower leaves turning slightly yellow, with reddish spots. The other three plants look ok. pH has been between 5.9 and 6.0. Calcium deficiency is supposed to hit the top leaves first and go down. My...

Hi fellow hydro (and soil/coco) growers, TL;DR: What ratio of NPK do you feed your plants? How did you measure it? Been doing some reading and research into NPK ratio's for growing cannabis, and have only found varying guidelines for the stages of seeling/vegetative growth/bloom periods. On...

First time grower. DWC question. After my seed is starting to germinate I will be putting it in Rockwool and hydroponic pebbles in the net pot. My question is do I fill my water tank up also with neutrents and water from the tank until the roots get big enough or just with plain water

Hello all! I've started on my 2nd grow in RDWC after finishing the first, but now armed with experience and the knowledge & help of fellow community members. Its now 8 days since soaking the seeds (unknown strain, likely indica) and 2 days ago I started addings nutes to the water. I think I...
