Thanks for that, DC. :)

Yeah, water has a tendency to follow certain fibres. I could look up the specific mechanics of the action as I don't know it off the top of my head, but I gotta get off the computer & on to op tasks. I can tell. D: RW floc saturates easily, driving all air out of the media and has the...

My cubes go into my Fytocell media with the cube tops level with the media surface. Fytocell has to be dampened with nute soln before the plants go into it. Same with pots stuffed only with RW floc. Starts the wicking action. Only in the case of using clay pellets is handwatering needed...

well, yeah. :D

OK. Mind you, I don't think you'll see the net result of crowding until it's too late. You might organise half of the area at 4/sf and half at 8/sf just to see the difference in real time. I don't think that your results will scale. I think that the combustion gen feeding small area will (come...

If the cost doesn't stress you, then flip a coin. It'll work well either way. Well, that's how my op is organised- 2x 1000 over 4 trays. New clones being introduced to flowering have previously only been under fluoros in my clone box, so I don't mind them having a bit of additional spacing for...

I try to harvest spot on every 2 weeks due to the production-line nature of my op. If I hold up some plants at the end of the line, I can't put more in at the beginning. Stuffs up the entire process. Honestly, I think that with 8per sq ft, there's going to be problems, not just from powdery...

Well, whatever blows your hair back, man. :D You'll get fine results either way. It's just more exxy to run 4x600, especially in acquisition, as you note. It's also another ~600W out of the mains to run the 4x600 arrangement, which adds up to +7.2kWh/day. I pay 16c/kWh, so it would be another...

Yeah, I'm still not fond of them and never will be. They're unsuitable for any recirculating hydro system. First, being organic material, they'll support mould growth. Second, in inorganic hydro systems which use H2O2, organic matter will break down and fragment. The fragments can clog pumps...

My dryer does not use a soldering iron as a heating element. It uses 6 x 25W power resistors. Back in the mists of time, someone asked me for a heating element that would be simpler to use than a bank of resistors, so I suggested using a 25W soldering iron heating element. In retrospect, that...

Yep, about 7' is bare min ceiling ht in a SoG/flood op. Yep, that's about double the tolerable density. You can get away with 4 per sq ft on the high & outside and that's with some pretty aggressive pruning of any branches that pop up. You'll want a sulfur 'burner' to keep powdery mildew at...

Just visiting. :) Well done! Keep at it. :)

I don't think 1" PVC will be strong enough. Do the aluminum tube with Qubeloks. All your pump has to do is fill the tray to the overflow tube (about 5 mins) and then shut off. Doesn't take much pump to do that! I'm thinking a $20-30 pump. Size is very non-critical in a flood sys. Pays to buy a...

Those are about the only things you need to get quite specifically from a hydro shop, yeah. I'd check local commercial lighting suppliers to compare prices for your ballast, socket, reflector, etc. Hydro shops often are competitive with other suppliers on lighting; they really make most of their...

dbo, the cost for the tray is a tick high (I pay about $AUD52 for a 900mmx900mm tray), the pump & fittings are about right, but you could save some big dough on the rez tank by using a plain old plastic storage tub from the dollar shops. 3'x3' is a good size for a 600 but a 1000 will improve...

OK, got curious & looked up the Stinkbud System. SB & I differ on a few notable points. SB veges plants before flowering, as opposed to my system which flowers clones immediately after they have developed a good root system. SB grows larger individual plants than I do but fewer of them...

yep, should be fine, it's the same stuff, just more water added. One caveat about using really low strength H2O2 is that below a certain packaged strength, stabilisers must be added to prevent the H2O2 from breaking down into 2H2O + O2 while still in the retail container. From Wikipedia...

@Bob Smith: mmmm.... hot girls with gravy! Too bad Sudafed spoils my appetite. :lol: @D4rKeN: thanks, gets the job done. :)

Thanks, Bob. :) However, you should know that I think that I've become allergic to airplanes- and especially those going to the US. Beastly place, so uncivilised- but for you, of course. ;)
