hey Al... I know this is kind of a crzy question but whats the difference between a exhaust fan/blower and a inlinefan?? if both can be used for exhausting a growroom and cooling a cooltube/air cooled reflector..
The 6 inch duct fan can provide more than enough cooling for your cooltube if it is not impeded by alot of 90 degree turns, a filter, etc...I was wondering if the 6 inch ductfan can cool a 400watt hps in a cooltube.. Or do i need a centrifungal fan for the cooltube??I plan on getting a 4 inch centrifungal fan with a filter for $119.. do you think i should put the 4inch fan on my reflector or leave the 6inch duct fan???
Yeah NLXSK1 is dead on about our homes in the US. I have 2 return vents that are very large. One of them is located just outside the door to my grow op.dang. Well, if greenstar can put in an exhaust that vents into the attic, he'll get the aircon into the space via the feed duct and will get fresh CO2 drawn into the grow, too, as the volume of air that the exhaust removes will enter the structure via air leaks.
Without a decent sized return (i.e. door closed and 1-2" gap at floor level) and with no vent to the attic, I have some concerns about temp control.
Cooltubes are 150mm dia, this blower is 8" (200mm)- and way too exxy. You don't really need that much blower for a cooltube, look for a 150mm, ~200CFM unit. I get them for about $35-40.My intenstions are to use this fan for the cool tube only. Panasonic Fans - (440 CFM 2.1 sones)$190.05
These Panasonic fans are far too expensive. Any fan can vent multiple spaces, but the inlet restriction to both spaces must be identical or one area will be well ventilated while one will not be. Better to use an individual exhaust blower for each.Also my smaller closet is 77" H X 24" W X 24" D, To haouse mother plants I wanted to use the same inline fan as the link but in a 240 CFM both those panasonic fans are designed for multiple-task ventilation. wanted to vent mums room and flower room with this fan Panasonic Fans - (240 CFM)
Also for exhuast fan I need two for both closets? to a Y fitting and into the filter is this correct or am I mistaken. if you have a diagram of how to set this up would really appricate.
should be fine.I was wondering if the 6 inch ductfan can cool a 400watt hps in a cooltube..
nope, you only need a centrif for the room exhaust blower, as it will be driving a carbon filter in your setup. The cooltube should have an independent ducting system, keeping grow room airmass separate from the cooltube air, so it does not need any filtering.Or do i need a centrifungal fan for the cooltube??
A 4" blower is really quite small. Whether it is sufficient or not depends on the volume of your room and whether or not you are running cooltubes. With cooltubes, the exhaust blower can move 1/3 of the room air volume per minute, i.e. a 300cu ft room gets a 100CFM exhaust.I plan on getting a 4 inch centrifungal fan with a filter for $119.. do you think i should put the 4inch fan on my reflector or leave the 6inch duct fan???
It should be able to control the top temp just fine, especially if the soldering iron element is well thermally connected to your heatsink.Thanks...so the dimmer can not adjust the high end temp of the soldering iron enough to bring it low enough for the dryer?
It's a fan motor speed controller. It's used to slow the fans down to make them a bit quieter (you don't need a wind tunnel to dry buds); also, in winter, slowing down the fans allows the air temp to come up to 29C even when the intake air is very cool (10-12C). It's optional, but you may find you'd like to have the ability to slow the fans down.Also, What's the MSC in that wiring diagram?
It should be in series with the LINE lead.Oh yeah, one more thing...My dimmer doesn't seem to adjust the temp at all. I've been moving it very small increments, but it just seems to turn on full power about halfway through the rotation? Am I wiring it wrong maybe?
I'd just tear the things apart by hand and pack the stuff in the pot bottoms.what is the best way to break it down to put it in can I just cut it in to small pieces to fit in bottom of pot?
40mm RW cubes, dealt with in much the same way as I handle clones.Also what do you use to plant germinated seed in?
Should be like this:What should be the flood level? I have it at about 9cm. (seemed about right)
5x/lights-on for small plants. Large plants can be flooded up to every 2h beginning at lights-on, avoiding watering in the last 2h of lights-on unles the plants would otherwise wilt without being flooded.How often should I cycle the pump? (I remember you said to run it just long enough to hit the top of the drain tube.
Yep, larger plants need to be flooded more often.Does plant and/or root ball size have any effect on watering times/schedules?
Either will work, but directly ducting air out of the tents into the attic will work better.Should I:
A. Run ducting from both tents to the attic (don't know how I'd do that at all, 1 ducting cool, but 2?) or
B. Get a bathroom type fan (the kind that pulls air out of the room, like when you drop science in there) and install it in the middle of the room,? I thought about this prior. I have a ceiling fan in the middle of the room. If I replace that with an exhaust type fan sucking air out, I could put it on a timer, perhaps.
Once the roots have escaped your netpots and are being watered in the DWC, it doesn't matter what happens to the RW cube. It is there only for supporting the plant before it is put into the pellets and automated watering system. Doesn't matter what happens to media on the tops of the netpots. If the plants are being watered, it's all good.my rickwool cubes appear to be very dry in my DWC setup......i have not seen any nute burn yet but i se rockwool and hydroton pebbles have white residue ( i am assuming salt from nutes) and look very dry what should i do
No. HID lighting can not be run on dimmers.
I mean i have heard that logn extenstion cords cause lights to dim so im guessing its POSSIBLE, Any light you want to shed on the subject? (hehe ... light... to shed... get it...
Really bad. All dead root matter has to be removed fully before you re-use pellets.Also how bad is it to have some dead roots in the hydraton? how thoroughly should it be cleaned in between uses?
Fytocell, perlite, rockwool, lots of options.What mediums in an :ebb n flow /grow system using buckets would you reccomend using OTHER than hydraton or MIXING with hydraton?
Pellets are used in certain systems specifically because they don't hold much water and thus can be watered frequently. Mixing an absorbent material with them defeats that purpose. You may not like that roots can't grow through pellets, but the roots filling the gaps between the pellets is more than sufficient.I Really dont like that the roots cant grow THROUGH the rocks, i like that with those mini grow cubes, soil, rockwool, and many other mediums, it can just grown right through it if the root wants to.
No. Inorganic nutes are compatible with H2O2.Also GH Hydro 3 Part is inorganic correct? meaning NO h202?
I had similar results with stem tip rot in aerocloners, but didn't usually have transplant shock probs. It's also the reason I went back to RW cubes.I would typically get root rot, even with H2O2, then during transplant they would always get shocked, and so I went back to basics.
Thanks for the offer....as you can see my old-school cuttings "a la Al B Fuct" are performing well. May get a 100% strike rate but only time will tell.The offspring on the heat mat look good so I don't feel it was gardener error on the ones in the EZ Cloner, same cut process, same hormone, etc...I'll keep you posted
