Received my microscope today. When I was trying to see if my plant had nanners or not, I happen to spot this critter. Checked my plants carefully and didn’t spot any more. I’ll watch for more over the next few days.

What is best practice for nutes in a DWC grow (5gal pails)? Do people just add fresh nutes to the existing water, or do a full water and nute change? Should this be be done weekly? Using my EC meter, my tap water measures at ~120 ppm before nutes. After adding nutes the ppm is ~350. Near the...

Has anyone here made their own LED light using the mid-power strips (not the cobs) for their garden? Im looking for advice on what is good selection of light color temps and mono-colors to use for 2x2 space. I’ve been leaning towards the Samsung Q series @3000k plus adding some 280 UV. Any...

I’m currently 3 weeks into my first grow. I have 4 autos that are the same. Currently they are all doing ok...I think...but anyways... One thing that interests me is about the differing effects of the trichome maturation. What I’m thinking of doing is trying to gain as much knowledge as I...

I have 4 autos that germinated July 24. I moved them to RW and into their baskets on the 25th(ish) with approx 1” of hydroton in the bottom of the basket to allow some air space. Of the 4 plants, 3 that have roots outside the basket are turning yellow. The 4th has no visible roots, and is...

Is there an easy and reliable way to test for potency at home? I’ve seen color changing test strips are available, but I learned a long time ago that I have color vision issues trying to accurately read faint color changes. Its 2019 and there has to be an easy and reliable testing machine...

DWC 5gal pails; pH 6; Kelp Mii added to h2o; Aglex 1200w led lights ( @ 30” above pails) first roots from seed are emerging from the basket. Until this point, I’ve had my water level just touching the bottom of the basket and have read mixed info about how soon air space should be created...

Question for my fellow canucks: As a licensed personal cultivator for med cannabis, can I write-off the costs of the grow equipment as a medical expense at tax time? What about the extra costs in my utility bills? Cheers YYC

What are the LED light needs of new seedlings? The info from my light’s mfg says their optimal height distance is 24” but I think that is referring to veg and flowering. I have 4 seedlings that are now sticking up from me starter pods in my DWC pails. One already has its first set of true...

Does anybody know where to buy that green film that is used on tents for the peek-a-Boo window to cut out that purple glow? cheers YYC

This is my first set of germinated seeds as I lurch forward into cultivating. 🙂First germs have popped today while on wet paper towel. One of them has already cast off its shell so the cotyledon leaves are exposed. The tap root is almost 1/2”. Should I put these in cubes or just the one...

Howdy! I’m new to growing and have decided to take the plunge into hydroponics. I’m a medical cannabis patient living in Canada and I’ve gotten tired of the high prices from the LPs. I’ve also applied to Health Canada for my personal production license. I’ll describe, and include...
