I curently have Exodus Cheese Auto in dwc under 300w led. Light schedule is 18/6 for last week, and 24/0 before that. My problem is that after 48 days plant isnt showing ani bud formation. It showned sex and preflowers but not bud forming. Its getting chilly now, and am losing time for finish couse of that. Grow room and dwc specs are all good as can be.

Any idea what to do? cheers

Hello friends, I'm on my first crop, and I chose hydroponics with the classic jack herer. I will use GH fertilizers, however I do not know how to give nutritious watering to my girls. Can anyone help me with watering period recommendations for them? Thank you, peace to everyone!

Product Description

EHG Ripener speeds up and enhances the ripening process in late flowering. Part of the Easy Hydro Grow range.

EHG Ripener signals to the plant that it is coming to the end of its life. The plant then speeds up the ripening process and reinforces its defences. Helps the plant to metabolise the build up of nitrate and micro elements which results in improvement in taste.

Contains:

Phosphorus P 22,6g/kg

Potassium K 38.5g/kg

Magnesium Mg 14,9g/kg

Directions:

5-6ml  per litre of water in weeks 7 and 8 of the flower cycle.

So i want to start growing again, havent been growing for 3 years now.

Last time i was growing in my balcony, but this time i want a real setup i can repeat all year.

I want to grow hydroponic in a tent... but it seems to be a real sience to find a complete set for 10 or more plants.

I want 600W light (or led, but seems more expensive) and carbon filter in my setup... and of course a hydroponic setup.

Can someone help me find a link for a complete set fitting a tent? my budget is around 700 dollars.

Can anyone tell me why two weeks in I'm only seeing very small growth. 

Water ppm just under 300

germinated seeds then put into 1 inch rockwool cube then transplanted to 3 inch rockwool cubes. 

After two weeks roots are only starting to come out of the end of the 3 inch rockwool cubes. 

Up until now the only feeding they have got is super thrive with every feeding and 3 inch rockwool cubes soaked in a small amount of flora bloom. 

I added a small amount of Epsom salt to the last watering because I don't know if the purple stems are genetic or it's got to do with magnesium deficiency. 

I'm moving them to 10 litre DWC buckets tomorrow then onto 25 litre DWC buckets when they get bigger. 

Temps 24 degrees 

humidity 70%

under a 300w led at the moment. 

Any feedback welcome. 

NUTES PH PERFECT

Thanks for any tips and advice.

I have a completely new set up 1m x 1m tent, Viparled 675w LED and my own hydropnic setup consisting of 32 liter plastic box reservoir, a cement mixing tray, airpots, water pump and a micro irrigation set.

Cement mixing tray https://www.amazon.co.uk/Plastic-Builders-Mixing-Cement-Plastering/dp/B017A085W2/ref=sr_1_1?s=diy&ie=UTF8&qid=1473076697&sr=1-1&keywords=cement+mixing+tray

32 litre reservoir https://www.amazon.co.uk/Wham-Plastic-Storage-Boxes-Litre/dp/6040194316/ref=sr_1_4?s=diy&ie=UTF8&qid=1473076744&sr=1-4&keywords=32+litre+storage+box

I have Airpots sitting on top of cement tray, which I've drilled holes in to allow nutes to drip back into reservoir underneath cement tray.

I used normal garden hose £5 for 15 meters and attached Micro irrigation https://www.amazon.co.uk/Selections-GF4001-High-Quality-Micro-Irrigation/dp/B001RCA2JO/ref=sr_1_11?s=outdoors&ie=UTF8&qid=1473076860&sr=1-11&keywords=micro+irrigation

My question is how harmful is the green algae growing on the roots coming out of the bottom of the airpots?

Here's some pics.

Hello,

I'm about to grow some white widows seed and im growing hydroponic and indoor. Even though i've been researching a lot is going to be the first time im growing and I have some questions and I was wondering if you guys could help me out.
01- I'm home-growing at a container that the dimensions are about: 1x1x0.35 (Height, Width and Depth, respectively) and we are planing to use 3 different seeds (both feminized), is it too much? Because since is my first time growing, I though having 3 seeds as a safety, because if one goes wrong, i have 2 more. 
02- I was thinking of putting two HID HPS lights, 50w and 4000 lumens each, is it good enough for a good yield? (the walls and ceiling both reflect 
03- How can i determine the NPK ratio of the plant (Hydroponic)?
04- Some of the data on your week-by-week video (the newest one, not the one 9 years ago), some weeks as time goes by you guys stop putting it, are they the same from the past week then?

05- What nutrients do you guys recommend it to put on the water?
06-How can I manage EC levels of the water? and is a EC probe good for determine it as well? 
07- I was wondering for the first week the informations about it, like temperature, humidity, EC, NPK... I don't think you guys report that on the videos.
08- How do I flush hydroponically? 
09- Would you recommend topping it? Because my space is limited, and I read online that helps for a better yield too
10- How is the smell of the plant? is it very strong?
11- The dresser is not air tight or anything, we actually made it the door, I'm having two little fans as well, I was wondering how often do I need to open it so the plants get some fresh air.
12- If I do this the right way, how much do you think i can get of yield? Or how much should I aim for?

I know there are a lot of questions, but I hope you guys can help me out, if you know how to answer any question please do, I cant find a straight and reliable answer online for these.

what can I do on the cheap to keep the room cool and mold resistant?

I usually get dehumidifiers but even then I get mold at top corners of walls. I need to eliminate this as cheap as poss.

Also, if I bring air into the room from the house will that be ok as air exchange? or pulling air from the loft in? 

thats my biggest pain.,.,so impatient,lol

My idea is to make underwater rotors(propellers, fans), what are waterproof, durable, and have connections in both ends, so you can put them between any water line(metal pipes, plastic tubes, hoses etc)

When you have alot of them in yout watersystem, then you could regain some power from the pressure of the water what is powering them by the waters moving power. If you have alot of them, then you could easily regain some electricity

You could make those things by any diameter and connection part, so you could easily put it anywhere...

PS: you could put like 2-5 in rotors in it(smaller hose, 5-20 in a lager pipe+ making those things, shouldnt cost much...you just need the same system in it like a hairdryer has, just make it waterproof and put it between a water line?

Is it a good idea?

Little quick thin i made in paint

1) Top view

2) 3D view

3) Electronic sketch ( you only need a genetator in there+ finaly a power suppy, what takes it all in, easy electronical physics)

how you reduce the ec value and how you increase the value ec

thank you for advice

I bin growing soil for some years now and starting up my first hydro, i am jusing powder feeding. It says ok the pack that the solution has to be (if useing tap water) 1.0 ec up from 0.7 ec tap water, my tap water is 1.0 will i then rise my ec level to 1.3 insted of 1.0 and so on?

Sorry my eng is bad

Bedst of smoke here from Denmark

my delemare is im using NFT method and was wondering how long to leave just pH balanced water in the tank to archive the best results for the 3 flush's to work or would it be better to forget the 3 flush and do a really good 2 week flush at end
