Here are some pics about what I meant

I zip tie the pots down also, they have a tendency to push themselves up when the get some monster roots.

Looks like you need to drop the plants down lower in the cups too.

I also just lay the tubes across the top of my res instead of using the racks - makes a smaller footprint on the floor, but if your res lid holes are already drilled it doesn't matter.

Also an air pump, like from a fish tank with an airstone, drop one of those down inside your resevoir.

Here is what I meant by zip tieing the pots down so they don't push out.



This is what I meant about the tubes filling up with roots.





tubes ontop of res to reduce space



roots in res



and last - a show off shot, 5 weeks 1 day into 12/12

How far apart are your plants?

About 10 inches

Thats the basic setup I bilt and have a complete grow journel in the journel section on the last grow I did in it. I built mine for under $150.You need to keep the ph at 5.8 in these no more then 6 and tds and ph and ppm are very important you have to monitor it daily as it will fluxuate quickly.Res temp is also very important keep it at 65 F in the res so it hits the roots at about 68-70 or infection, algae and bacteria grow fast.Good luck

I like the zip starps I was looking for a good way to help hold them down and you have it nice job. Your square tubes hold lot more water then mine as mine flows and drains like a quick stream and my roots are always intertwinned in giant 10 foot long root mats.Once the go in thiers no coming out

Got any good pics fletch? Very interested in seeing.

Looked for you journal - gotta link?

this is the best way to grow I think, super results.

very nice kelso

I cant believe your growing 40 HYDROPONIC plant for your first time. You could have saved your money instead of getting such a huge system and got better lights. YOU NEED MORE LIGHT.

awsome setup man, Im building the same thing. but for real now u need good lighting. this is going to be my first time growing too, pick up all my soil and bucket, had some spill so i said f*uck this mess im going aero. Is much harder but when u have a passion to do somthing u tend to do it right. Do so reading get some equipment find a chart and go ffrom there.
