fvape penn dosen't hit whats the prublem

I will teach you the easiest way to get a pound or close to it from your 600 watts by going drain to waste (pot + pro-mix + GH 3 parts) if you are willing. I will help you with any problem you have through the first harvest. The offer is there, no secret sauce, just really basic growing knowledge. I also always had great success with using one big ass box for dwc that can hold around 17 gallons with 4 plants with an access hole in the middle for daily top-offs instead of round buckets.

Either Lowes or Home Depot sells them with the yellow covers. Instead of dealing with 4 buckets you only have to deal with one box. I appreciate the offer but really am set on a RDWC/DWC set up for now. I will take a look at DTW systems though in the mean time. Seems to be about as much work as RDWC and the results are there. If I decide to go this route I will definitely PM you some questions. In a 4x4 tent you could use a single Rubbermaid tub for a few plants and ScroG the lot. Easy-peasy except for keeping the temps down in the tub.

I wanted to go RDWC so I can locate my res outside the tent eliminating the need for a chiller during the winter. Even now when it's 25c outside my basement stays at a perfect 17c. Gives me lots to think of before I spring for the purchase button. Like you I had my heart set on RDWC I made myself a brilliant setup with all bells and whistles, I thought it was going to be a lot less work and plain sailing. RDWC does work very well for some but at some point you will get root rot and thereafter it will always be a threat lurking in the background waiting until you let your guard down before it strikes. RDWC looks great on paper but in reality I found it took just as much time as DTW and due to PH fluctuations it was almost impossible to take a short vacation and leave it ticking over. I have had a few monster grows with the system but it in no way makes up for the lost grows I have had. Problem with DWC can be this: When your rootball gets bigger and bigger, there might be a risk that the water inside the rootball stays there. The bubbles do agitate the surface; that's what is getting the oxygen in the water. If you would pump out your water now and then, you could avoid this. You could also replace the 5 airstones by a normal pump and just pump the water around the res. The stagnant water in the rootball will be also refreshed then. With RDWC you could perhaps also avoid this stagnating water and you could also get rid of the airstones. did your friend also tell you what he his yield is? I am asking because changing his reservoir just any 3 or 4 weeks is not a lot. It's amazing how little space the roots actually take up. I was growing 16 plants in one RubberMaid tub and it was right full of roots. When all the plants were harvested I cut all the roots off at the netpots and left them in the tub. Filled it up with water to the line then removed the roots and measured how much water it took to go back to the line. Just under 2L so that's only 4% of the volume in that 50L tub. Tub was bigger than that but 50L filled it to an inch below the 5" netpots.

I'm thinking if I've got to invest in a water pump I may as well get an outside res and go recirculating. He yields about a 3/4 pound to pound every run depending on strain and effort put in. Not overly impressive yields but much nicer and denser than I yield in my current soil set up which is about slightly under a QP but flower in a much smaller area and use a 400w HPS.

Now that I've got the space I'd like to expand slowly starting with adding a 4x4 and using my 600w. I'll use my 2x4 with T8 for a mother and clone starting. Later down the road (next year) I'd like to add 2 more 4x4 tents. I could then keep 2 tents in flower and one in veg as to achieve a purpetual harvest every 4ish weeks.
