Hey Al,
Can you please tell me everything you've said in this thread so far. It really seems like a big hassle for me to read it when i can just get you to tell me all about it.
seriously though, good on you for being so damn patient. I would probably kill someone the 93rd time i got asked how high to flood my table\what nutes to use\how to hide this all from my mom.
You ever find your way to Canada i'll take good care of you.

Cooltubes must be able to source cooling air from outside the grow room airmass and dump it outside it as well.
If you can establish the airflow necessary for cooltubes, you will also be able to ventilate the room.
So, you germed your seed, got a roughly 1/4" long taproot out of the seed and planted it in the holes in the RW, right?
WAY too wet. No wonder nothing's happening. The cube must only be damp, never wet or saturated. No way a seedling will take enough water out of the cube to justify watering 2x/day. For this situation, cubes on a heat mat (you DO have a heat mat, right?) will only need about 5-10ml of water/day, on the very high and outside... They may not need water every day.
yep, fine.
However, you're not growing an aquatic plant and don't need to give anywhere near as much water as you are. You should not be able to shake any excess water out of the cube- it must be damp, not wet or saturated.
Thermonuclear weapons? Dunno. It'd be very hard to affix a heating element to glass. If the thimble you use is stainless steel, it shouldn't flavour it.Any ideas on how to heat up the glass bowl?
no wucking furries.Thank you uncle Al
coolio.Thanks for the advice again Al....i worked out the fan controller basically just undo the 4 screws on each corner and then fix in wires, bit like a plug.
farm out, mang. check discount shops for the plastic pots, see if they're blowing out the ones in ugly colours for cheep.I will be buying some solid pots tomorrow i did have a feeling they were the wrong ones but they came with the flood table kit so i just used em...im paying a trip to the hydro shop tomorrow gonna get myself a cooltube and an intake fan.
If you draw cooling air for the cooltube from the room's airmass, temp stability will suffer. The cooltube blower must run all the time that lights are on and thus cannot be run on a thermostat. The cooltube and room need separate blowers.Al, another quick question if you dont mind, im gonna suck air through my carbon filter and then push it through the cooltube then out the exhaust, is this ok. I dont have enough intake/extract vents for the time being but this should be ok for my 1st grow shouldnt it. Im gonna test it out tomorrow
Yes, using the motor speed controller will be great so you can adjust the setup so the room is at negative pressure.i think i should still be able to use my fan controller but just set a higher idle speed for the extractor fan.....what u think????
no prob.And all thanks to Al B Fuct who must be a flood and drain LEGEND.....keep up the good work
No- water the cubes by squirting water on the underside of the cube. Invert it & squirt away.One last thing, when the time comes for watering 5-10ml would it be wise for me to pour the water directly on to the seed so it doesnt die due to dryness?
Wet the perlite thoroughly from the top before plugging a cube in it. This will start the wicking action, assuring there's water in the rootzone, but the tops will dry out. Don't top water in future, only just before plugging the cubes in. Wicking to 2" below the top is ideal. This will assure that the roots will find water but the medium tops will remain dry, preventing algae growth on the top surfaces.When I flooded the table the moisture never reached the rockwool even after setting overnight and a repeat flood the moisture never wicked closer than about 2 inches from the top of the medium.
No, the media tops should remain dry.Should I add some vermiculite or some other wicking type of media to this mix? Or am I wrong in thinking that the top of the media should be damp after a flood.
Yep, that's fine.2) My table takes about 5 min to flood and about 10 minutes to drain are these acceptable times.
No worries.Thanks ABF for all the posting you do on this forum.
Usually when you see wilt occur which is due to overwatering, it's not a one-time event. When plants are drooping it's because there's been some root rot that's been taking a while to destroy enough rootmass such that the foliar mass can't be sufficiently supplied anymore. You say your roots are bright white in the bottom of the pot, so I'm not so convinced it's root rot.so my question is.....
Is this likely to be an acute isssue from the extra watering yesterday and if so will it sort itself out once allowed to dry out sufficiently??
yes, this is a useful rescue method. Not so much a soak as a dip, though, enough to saturate the rootmass with a fairly strong H2O2 soln, about 10ml/L. Allow them to dry back significantly before watering again.Would a soak in a concentrated solution of H2O2 force some air back in the root zone and aid recovery. I have seen others post about using this technique on overwatered specimens and wanted to hear you validate it.
If this is an advisable method what ratio H2O2/H2O should be used.
I agree. Should work great. If the blowers are too noisy, you can always put motor speed controllers on them. A blower running at 80% max speed may only make 50% of the noise. Good quality centrifs are damn near silent, though.My exhaust fan wasn't a centrifugal fan, so I am returning it and going to get it done right. Probably just going to use two centrifugal fans of equal cfm. Think that because the duct is so long, this will work best.
Just to be clear, you want to alternately run 2 lamps on one ballast? Say one in one room for 12h and one in another for the next 12h? That's pretty easily doable.howdy
Do you know if there is a unit that will allow me to switch lights on a single ballast, they have expensive controllers for 10 to 20 lights.
do you think we can put one together on a timer,relay
What's a homebox s?Hello, can anybody tell me if it is possible to have a 400 wt hps in a homebox s?
Is that LxWxH? If so, a 400 is a good match for the floorspace.The dimensions are 31.5" X 31.5" X 63".
For about $60, you could have one. Will also take about $40 worth of fan & about the same in aluminium flexiduct (as used for range hood ventilation).Or, would that be too much heat. I dont have a cool tube, which may be a problem.
Cooler weather is a blessing, but it shouldn't be part of your longer term grow room operation plans. Problems will come right back in the spring.I have a 4" intake as well as a 6" outtake that are both hooked up to 80 cfm inline fans, as well as an internal oscillating fan. Also, it gets very cold in the winter where I am so I figure that could help with the heat a littlebit. Any suggestions would help. Thanks.
that is what i want, that should help with the temps and evenly distribute power consumption.Just to be clear, you want to alternately run 2 lamps on one ballast? Say one in one room for 12h and one in another for the next 12h? That's pretty easily doable.
