I soak in 1% hydrogen peroxide (1 part ordinary 3% and 2 parts water). It precipitates oxygen bubbles which form on the shell, holding it to the surface. Less chance of drowning. And, it disinfects germs on the shell, which could be good (you don't know how they were handled, what conditions...

Autos are feminized too. I think you're using "fem" to refer to photosensitive. Autos are best for outdoor growing. You get a much earlier harvest than you would if you planted early and had to wait for Fall (a photosensitive). Indoor, I like them because they are smaller and more naturally...

I don't think it's possible to do. A GFCI outlet would be easier and, ultimately, safer. You can either replace a wall outlet with one. Or, make a general-purpose extension cord with a GFCI outlet on the end. (Just some 3-conductor wire; a 3-prong male plug attached to one end; a junction box...

It's part of it. Also knowing what to expect, how plants respond to more N, or more P. Knowing how to LST without even thinking about it (just because you have a feel for how it folds over). Knowing when to LST instead of second-guessing it, or not anticipating its need. You'll know when you're...

The link in my sig? It's this: https://forum.grasscity.com/blog/10656/entry-13868-how-i-grow/ MiracleGro Tomato works well too. I'm growing a plant with it right now. A lot of people will tell you it's not suitable for cannabis. But, so far, my experience has been very good. I think it gets a...

It's just a style you acquire, a second-nature about what works, what doesn't. You become more tuned into the plant's condition ("reading your plant"). You'll know it when you're there. It takes 1-2 years. If you want to develop that faster, a perpetual grow would work well. Start a new plant...

I've never heard of anyone growing tobacco with cartoon-labeled bottles either. IMO, if someone salts up their plant with a typical boutique, multi-bottle "lineup", bloom boosters, etc., "flushing" might make sense. I think a lot of this stuff gets confabulated into a one-size fits all topic...

You're in soil. Why would you choose hydro nutrients? Jack's Classic is often used (inexpensive, simple). I would lean more toward organics. What I use is in my sig. It costs about $1 per plant, per grow, but more organic. If you're unsure what to do, I'm using MiracleGro Tomato right now and...

I doubt that.

If that's a criteria of "worth the money" I've just found a goldmine with MiracleGro Tomato. That plant is in a 2gal container and has a fan leaf that looks like a gigantic elephant plant.

Why do you want to use that? Aren't your nutrients sufficient? This is from the label: QUANTITIES often reported successful for MOST purposes- for active development or resisting stress: 3 FLUID OUNCES PER 100 GALLONS water (100 ml. per 400 liters), (1 tablespoonful per 15 gallons), (1/4...

You should focus on your NPK ratio. Use this spreadsheet to figure out the ratio from whatever you're mixing together. Change the mix to get different ratios. Basically, finishing at 1-2-1.5 is good. You could increase P to get 1-3-2 once or twice near the end. You just need to be careful...

See my sig. Everything I do is documented there. I do a combination of organic (for taste) and synthetic (for immediacy). It works really well. Myself and friends noticed a big difference after switching from all-synthetic General Hydroponics (now Scotts, Monsanto-friendly) Flora 3-Part. I...

I'm in soil and I like to monitor my PPMs. I start with 150ppm water and add about 300-400ppm nutrients. I try to feed enough volume for 10-20% runoff. I monitor the runoff ppms to see salt buildup. I either increase runoff or decrease strength. (I tend toward 20% runoff and stronger nutrients...

Jan 20 (Day 56) 20th feeding. 3.0g/gal. 438ppm measured (143 water + 295). Runoff: 1350ppm. 10% runoff. I reduced the UVB 10 (compact) bulb from 1.5 hours (15, 15, 30, 15, 15 min). I started to use it 2 hours per day on Day 44. I'll reduce it to 1 hour per day in a week or two. (I could...

Premier Horticulture recommended 5.9 when asked. I used 5.8-6.0 in veg. And, 6.0-6.2 in flower. For runoff ph, google for "NCSU Pour-Through Runoff Method." That's the most accurate way to measure runoff ph. If you think about the two factors involved in that, you'll realize why casual runoff...

Have you looked at CMH? That seems to produce more usable light per watt than the typical Amazon/eBay epi-whatever LEDs (less heat). Otherwise, you have to spend $2 per watt on efficient LED like Area-51.

That's a good idea. The foil "duct tape" would be easy to line inside the GE's diffusor. It's already sticky on one side. I'd like to get a Phillips 14.5w (100w equiv) to see what it looks like with the diffusor removed. Its base kind of flares out a lot. If the diodes are forward facing (like...

I think a slightly better candidate light is the Phillips 14.5w (100w equiv) A19. (the round light, not the flat-top). That's 1500 lumens (103 L/w) compared to GE's (16w/100w equiv) 94 L/w. If the Phillips diodes are front facing too, then it should be significantly more L/w than the Cree...

I think the L/w published on the box is relatively meaningless because, as mentioned in this thread, that measures how the diffusion cap disperses light omnidirectionally. With a Cree (88 L/w) you have to mount it in a reflector to get directional light. The diffusor can be removed from it and...
