hydro help

[newbt2grow]

:reallyexcited: Hi I got a hydro set up for 1 pot i worked out every thing but which way i use the perlite and clay balls it is all new to me i like soil but thought that i would give it a go thanks

basically you use clay balls in a flood and drain type arrangement, where the pot is filled up with water on a timer like 15 mins every 2 hours. The clay balls dont hold any nutrients, or water.

 

Perlite is more often used in a soil as a conditioner or it can be used alone but it also doesnt hold alot of moisture.

 

Really we need to more than you have a pot, is it a hydro pot(dutch) or a standard gardening pot?

 

Have a good read through our faq area or indoors area. most of the info is here you just need to search a bit for it.

If you can spare a bit more time telling us what lighting, pumps, timers etc you have then we can help more.

I took a few pics the light is a 250w osram thats all i know about it. I have a 400w light on order from sa hydroponics the water pump is a Atman 1100LPH. There are 2 computer fans sucking air into the box and a desk fan moving the air around all fan are pointing at the light and for some reason y pics will not attach i will keep trying Edited October 7, 2004 by newbt2grow

You can make a passive intake.. what fans have you got on the exhaust? I dont even use intake fans, no need. Get a good exhaust fan and you will have no problems. The 250W Osram light sounds like a heat lamp or something, dont use it unless its a proper metal halide or HPS.. you will just waste your time.

I am not using exhuast fan at the momment i drilled 6 2inch holes in the roof and the air flows out quiet well

Like Nath said, exhaust is more important than inlet fans.

I use inlet fans on one unit and passive vents on another.

 

I would use your fans one as exhaust and one as inlet or both as exhaust.

Reason being that the plant needs more than air it needs the co2 in the air.

 

250 light could be anything, whats written on it?

If the 250w light your talking about has no remote ballast.. then its useless. Its a heat lamp from what I can remember, Osram dont make hydro lights, they make kitchen and bathroom heatlamps and household globe products. I dont think they even make fluoros. Get the 400w and your grow will be alot better.. Im finding the 400ws to be too small now even too 1kW here I come!

Hey Nath,

osram do make grow lights, and some HPS dont have a remote ballast. they are built in to the reflector etc.

I will try and find something to show ya.

 

I wouldnt go with a 1000, 2 600s would be better coverage.
