Think again. A 600 will produce poor bud density around the edges of a 4x4 tray. A 1000 is the right choice for that large a tray.

kewel beens. :)

Use the kW. A 600 is just that little bit too small for 16 sq ft.Wrap that rascal in a cool tube with a closed air circuit.

Clever, but what if it is a male goat that has been sacrificed under the light of a waxing 1st quarter moon? Ever tried to milk one? Did you make a new friend? :D

All sounds good. The only change I'd make to your notes is that you really only need about 25mm of tightly packed rockwool floc in the bottoms of the pots to keep the Fytocell crumbs from washing out of the pots. Yes, a carbon filter is fine for scent control. In fact, since the writing of the...

A plain old fish tank air pump and a large bubble-curtain type airstone running continuously will do the job. The bubble curtain 'airstones' I use are not really stones. They're a tubular foam material with a stainless steel tube inside which keeps them from floating. The compressed/glued...

Hiya. I don't have a lot of time at the moment, but I thought I'd drop in and suggest that I'm not dead. Much. A few quick notes... It isn't necessary to use enhanced spectrum lighting for flowering cannabis. It wants a yellow-red accented spectrum at that time and HPS suits ideally. You can...

Hiya. I haven't had time to answer anything and I won't for a few days; I have a gravely ill family member. Back when I can. Sorry.

Thanks for that. I'm following this thread for a while: https://www.rollitup.org/hydroponics-aeroponics/399206-its-fuct-world.html Been fairly busy and can't answer all questions immediately, but I'll be around for as long as I can, until answering queries clashes too much with my other work.

No worries. That'll do. 5 mums should do it. You might want to start with 7 and reduce to 5 when they're all a bit more developed. After several passes of cuttings, the mums' stems will begin to get woody. When the woody bit is more than about...

My only comment on spider mite eradication was to buy a miticide containing abamectrin/avamectrin. Rotsaruck finding it, it's a restricted pesticide in some localities. Worth buying & having on hand before you get spider mite. Long shelf life, having it on hand instead of having to fish it up...

The size of tray pumps is really non-critical. Can be the smallest pump in the shop that can lift the water to tray level. Bigger pumps may fill the tray faster, but that's not important in a flood system. Bigger pumps, however, may be built better and may be more reliable in the long run...

Gotcha. I hope it produces at least a metric fucktonne for you for all the work you've put into it. You're more ambitious than I am. :) Very interesting. I hope it's easy to maintain and reliable for you. :) Noice work. :)

Thanks, hope all is well for you, too. :) Kinda interesting; I like the central lighting- light loses intensity when bouncing off a reflector. However, the setup looks really complex & expensive. I think I see some kinda dead looking plants in the 1st photo. What happened there? Thanks...

OK, now I'm annoyed. I just spent 45 mins replying to several of the 2 pages of questions waiting for me, hit POST and the RIU board threw an error and LOST THE FUCKING LOT. If this happens again, I'm NOT going to bother re-writing all those answers. I simply have too many...

Now's as good a time as any to draw the gentle reader's attention to the adventures of Stoney McDoper in https://www.rollitup.org/newbie-central/10004-how-not-grow-dope.html And let me tell you, after the last few posts about LEDs and ordinary fluorescent lamps coated in a very thick layer of...

I feel some Stoney coming on. https://www.rollitup.org/hydroponics-aeroponics/399206-its-fuct-world-15.html#post5176938

Hygrozyme is an enzymatic cleaner. Enzymes are proteins. Proteins are organic matter. H2O2 will break down enzymes as though they were pathogens. So, no, you can't use them together. Yup. That'll be fine. No. Fill the netpots with clay pellets. When your clones in RW cubes have rooted...

Yeppers. Ditch the hygrozyme. Deal with pathogens using H2O2. Use 50% grade at 1ml/L every 3-4 days. Run the single tank at 1000. The younguns don't really need ramping up and the mature ones don't really need flushing. Netpots will air-prune the roots so they don't fill the tray. There will...

Keep paying attention and we WILL have more like me- such as you. :) Definitely. RW floc is highly absorbent, so you can't water often without causing root problems. It tends to hold more water than my biggest flowering plants in 175mmx175mm pots could use in 24h. Using smaller pots can be...
