youll want barely negative pressure with fan on. (causing walls to slowly and slightly pull inward.) Make sure ur humidifier is ultrasonic, not evaporative. You wanna be able to SEE the mist/moisture its making.

Personally woulda added a fan speed adjuster, rather than replace it, but im lazy. How far from the exhaust filter are you measuring your RH? Toss up a pic or 2 of the full setup, not just the lighting+exhaust, maybe theres more variables....

G13 labs baby... solid seeds, never a worry of if it will germ, or if what germs will be a healthy vigorous plant... excellent genetics.

No fuckin' doubt dude.... I grew with advanced for years, knowing it was mostly water and costly... for the simple reason that it worked. After a sample size pack of Megacrop and a side by side comparison grow.... Ordered the big ass bag of Megacrop. (Make sure to keep it in an airtight...

Alternate between a 4 bar T5 24" set, and a 125w CFL (the big ass bulbs, not 125w equiv. but actual 125w) Mostly depends on what kind of small veg plants are active at the time.

Thank you for this post. The illustrated teardown and supplied part number made this repair an absolute breeze! Fixed my $90 fan for about $2... I agree, this is something that should be set up as a scheduled maintenance thing... Ill be keeping half a dozen bearings and a pair of capacitors on...

C. M. H. All the density and yield of HID lighting, at a fraction of the heat and power costs... Replaced my 600MH/HPS lights with 315CMH and have never been happier. Went on to replace my 1000w HPS lights with 630 double ended CMH... Flower room dropped like 10degrees easy. And its so bright...

Just dont... Order in small batches from attitude, and always invest in the insured shipping just in case customs empties the package. (Ive only ever had it 1 time) Going local is just gonna cost you 4x as much for something you can be half as sure about the legitimacy of.

But worth it, no? I recently swapped my 2x600w MH's for 315 CMHs, and my 2 1000w HPS sets for a pair of 630 CMH DE's.... (added another 315 in the center later, only in use during peak flower) The reduction in heat and power alone is a blessing, and I am not seeing any depreciation in the bud...

Is it a decent LED? Or just a cheap one? Your T5's may have been better depending on the type/model of the LED panel....

Its still totally an option, just have to install a fan that exhausts the attic.... but then ur doing 2 fans instead of just the one. Its super common for the bath fan to exhaust out the roof, or side of building, and you should view it as an upgrade to the existing residence. Its not grow...

actually.... thats not accurate. Several studies have been done to see if plants react to music... the results are almost always either "inconclusive" or "Plant __ benefitted compared to control" For a real trip down the wormhole, check out the studies done to see if plants feel pain, fear...

If you decarb it, cant you just melt it into some warm PG/VG or a combo of the 2? Just guessing....

Just put a simple cheap slap it together shed up.... And the question is valid, what state are you in that medical patients can grow cannabis where public can see it?

Simple answer? No. If you cant have weed taller than 12" ur fucked. You have to remember.... it grows buds, and they grow UPwards. If its a legal grow, just invest $200 in a digital cam + dvr setup, so if you DO get ripped off, you know exactly which neighbor to go beat the shit out of... (i...

USA, but Michigan, rec legal, and shaking hands with the Canadians!

4bid. one application. I found a seller selling 1oz sample bottles from a hydro show... shits expensive as fuck for a reason... It works. It works in one shot. It works on all stages of mite, eggs included. And it stretches.... I treated my veg and flower rooms with a couple ml...

clarify... venting the dryer into the garage of course will be moist.... venting the grow into it, no...

link it up, im in the market soon... love my 315s in place of the 600s, planning to swap 2 1K's for a pair of DE CMH, but want DE not dual bulb... little rarer
