Did a quick search and haven't been able to find anything quite like this setup. Can someone tell me if they've done this and if they can paste the code here it would be great! Objective: Automatically water plants based on moisture need during lights on period, replacing the need to fiddle...

Dr. Who - the ballasts are located outside. Those things crank the heat! I just thought if it was possible to insulate the hoods for a few bucks and 10-15 minutes of work it might be worth it. I saw some other insulation that was R-12 for wrapping pipes that I quickly crunched the numbers on...

What have you all used to insulate your hoods? Reflectix looks like the easiest to use non permanent solution but it has no rated R value. If someone has used reflectix can you give me: A) Room temp B) uninsulated hood temp C) insulated hood temp The reason I ask is there is another...

thanks!

So suppose a drip system were used with 4x4x4" rockwool and they were flipped as soon as they were transplanted from clone for a 9 week flowering strain, is that enough media or would it be necessary to put say a coco mat under?

I'd say another week or two, more? thoughts?

How much would you say she bulks up in the last two weeks of flower? Do you start counting when preflowers or at the flip? I'm just wondering because at ~55 watts per foot of LED (Mars hydro) there's a ton of puff ball buds but not really very many huge colas at 7 weeks from the flip (roughly...

Here they are at roughly day 42 (from the flip, ~2 weeks for flowers to show), a roughly 1 week update. I switched water (1.5EC mostly carbonates, same ca, mg, and fe as calmag) This caused me to use a lot of pH down, bringing sulfur to 300ppm from sulfuric acid. Currently dosing with...

Just scanning through this thread there's a bit of misunderstanding. The op was right in his original post, if I read correctly. If you continually flower f2,f3,f4,f5,f6..etc generations back against the original mother they will be more and more like her. IF she was homogenous to begin with...

Forgot to add, what ratios do you recommend?

My dosage ratios are: 2mL of dripclean 5mL of foliage pro 12mL of calmag This is based off of the 0.4mL of dripclean per gallon so the one gallon ratio would be: 0.4mL of dripclean 1mL of FP 2.4 mL of calmag my calmag is: Threw in my silicablast copy for free ;) but I'm not currently using...

Well I don't think any of the meters are ever right as I've never gotten a consistent reading between any two (and I've had some expensive ones). As long as they're consistent that's key. I may see some salt buildup in the cubes, which shouldn't be there? It's just white buildup at the top...

Since 1991, I know they seem to be lacking in a few areas, any recommendations on a 2 part that is good for ro water and LEDs? Homebrewer, I'm using an inline ec meter connected to a robomatic doser. My handheld reads 0.4ec when the inline reads 1.2. Homebrewer, look at the state of...

Roughly, it was at 1.25 mL roughly 1.2EC but I was getting tip burn, now it's at 1.0EC. I have another thread in this forum with a few pics from yesterday - someone thought I was deficient but I have burned tips from the 1.2 EC...

I think they're supposed to fill out in the 5-7th week. That isn't a deficiency, it's nutrient burn - the bubba kush got it worse than the gg #4. They're very nute sensitive/possibly a little build up from twice a day feedings at 1.2 EC (I've bumped down to 1.0 now) even with dripclean in the...

How do they look? GG #4 in the front, Bubba Kush in the back.

OK, so this whole FP is really starting to confuse me in regards to nutrient ratios and horticulture knowledge. @Uncle Ben recommends it highly, but I believe he mostly grows in dirt which may contain some nutrients of its own made more available by the bacteria in the rhizosphere. @homebrewer...

So I have a few strains I'd like to grow out and try breeding together combinations of in order to create a more Apollo 11 genius type strain. I want to get a strain that's fast finishing (at least 6-8 weeks), large yielding, very heady sativa high that is super social yet introspective and...

So I tried to run a ground from the sample pot screws to the cement floor and see if that changed my readings, it didn't. I then tried to run the ground to the ground plug on the wall, this also didn't change the readings. What really gets me is that in the sample pot I get this crazy high EC...

Anyone use it? Can't get it to work personally. I mean, it works - but the pH and EC are so far off what they should be it's nuts. I think I may try running a grounding wire from the sample pot to the ground to see if the moving water is causing a static buildup in the sample pot and...
