SIP thread -- (Sub-Irrigated Planter)

[Humanrob]

I have a fan on above and below the canopy. I know if I turn my exhaust fan on continuously I can get my humidity down to 55%. The only problem is running my exhaust continuously will drop my temps down to around 75 - 77F which is a bit cool. I'd like to keep my temps up in the low 80's if possible. So I'm in a bit of a pickle. I bet when I and if I add a few more COBs to my light I will get a bit more heat and my exhaust fan would kick on more often and also take care of the extra humidity. But right now I'm stuck. At some point I may just run the exhaust full time and accept the lower temps.

That's a tough one. Since they haven't started to flower yet, you could give them a good soaking with GreenCure. It seems counter intuitive to wet them down when humidity is an issue, but I've had great luck with that product as a PM preventative. Just a thought.

I use Actinovate as a soil inoculant and also a foliar to prevent PM. I've had good luck with it. It will hold PM at bay even on zucchini.

i plugged in a few CFL's under my canopy on the last grow,, not for the light, but for the heat,, and it worked like a charm
Oh your plants looks crazy good, nice job on the canopy training, its going to be a fun ride to watch these flower out

i never saw any sign of PM on my last grow using green cure,, did a few sprayings in veg, and a couple in early flower,, and then let it ride,, i like the stuff,, and its just sodium bicarb very simular to plain baking soda,
i will use it every grow from now on

That's a good idea. I may just try that.

Did you pick a specific kelvin for your CFL's or does it even matter?

Lol nope but the lower buds improved but i put them in there for heat so i could speed up the exhaust fan to help with humidityand it worked

if you are looking for heat as opposed to light get a reptile light or something like that.. only about 8 bucks at most pet stores or big box

Help guys i got fungus gnats. I did a straw alphalfa mulch with living mulch growing in. Plan is to ditch that the mulc layers. Next would covering the container up with plastic will that help or make the problems worse.

I have nematodes on the way too.

They got big...they as in it....i have other SIPs

@human rob has dealt with bugs like this I think,, maybe he can share if the plastic cover helped,, myself i ran the plastic the whole ride and didnt see any bugs

 

[frankslan]

@Humanrob hey did the plastic cover help with the gnats.

 

[Humanrob]

Yes, plastic definitely helped me. Try and get a decent seal (gently, obviously) around the trunk of the plant and the edges of the container. I've used plastic garbage bags, cut a slit down one side so I could drape it around the plant, and then duct taped it up. Not elegant, but it seems to disrupt their life cycle.

GoGnats is cedar oil, it's said to help with fungus gnats.

Cedar's naturally insecticidal, if I'm not mistaken. I learned that while researching a substrate for my tarantula.
