My first DIY ebb n flow. Setup. - Indoor Grows - Hydro - International Cannagraphic Magazine Forums

Hey.

I've done a couple of grows and will finish my first hydro grow in a few weeks. Now I'm trying to set up my first E&F and could use some input.

I'll be growing under a 600w hps (hoping to invest in cobs later) in a 120cmx120cm tent using a 100cmx100cm tray that is 12cm deep. I want to use either a solid lid or panda film to cover the top. Thinking nine 12.5cm netpots filled with hydroton. The rest of the tray will be empty. This means very little medium to wash and hardly any risk to overwater the plants. The lid will keep moisture inside. First question is if 12cm is deep enough for the tray? It's the only size I've been able to find. I'm thinking flooding it to about 8cm.

The rez will be 150l. Since the tray hardly contains any medium I'll be flooding quite frequently. I read about flooding 10-15min every hour. If I do this, do I even need to circulate the rez to keep it aerated? The constant floodings should do the trick, right? And about the pump. What size would be adequate for this setup?

Thanks for reading and what do you think? Will it work or do I need to change something?

I will for sure post a thread as soon as I get this going.

1/3HP should be fine for the pump, in a tray that size. Shouldn't need anything extravagant. And I bet you could get away with doing even a bit less than 10-15min/hour until they start to get bigger. Best of luck!

Best of luck! __________________ It's time for a revolution, but probably not in the terms that people imagine it. The word conjures up images of— a modern day version of peasants going into the street with their pitch forks to go after the bad guy who lives in a big house and we're gonna get that son-of-a-bitch and we'll take all the stuff from him and we'll give it to the workers. That's not the kind of revolution I had in mind. I thought that it might be nice if it was handled a little bit more modern and efficient way, without people getting slaughtered. It's a matter of infiltration…The people who are in control of the media, the government that run the lives of the average person in the street. They aren't doing a good job 'cause they don't really care. The potential is there in the younger generation. Right now they’re not really interested. Their political involvement is on a very superficial basis. They go out for the social aspects of a march or a rally rather than for what it could possibly accomplish. -FZ
