Humidity becomes more of an issue as plants are blooming. You'll be fine as long as the humidity does go down in the next few weeks.

I'm confused... up to 91 degrees and you have a heater in the tent?

Assuming you don't know his kids or what school they go to... do you have kids? Anyways, the point is there is a difference between 'drugs' and a plant. Especially where Cannabis is concerned. The goal I think is to teach children to respect that plant. How do people deal with explaining to...

Aerate and use immediately. Never stop aerating and let sit around, it will become anaerobic. Maybe after 20 hours it'll be closer to neutral. Either way it should be fine to use, the soil should manage. Pretty sure I used blackstrap molasses with the Earth Juice also.

There's no need to do any drugs now, man... How much it's going to cost depends what you pay for electric, look at your bill. It should tell you how much you pay per kWh (kilo-watt hour). The light for example, the 600 watt ballast actually draws 660 watts AFAIK (rated wattage +10%). To convert...

... Seriousfuckingly?

Absolutely no need to adjust the pH of any irrigation or most fertilizer solution in good soil. Depending on the planting mix you use the pH is usually supposed to be about 5.8 to 6.5. Sphagnum peat moss is acidic and liming agents are used to counteract the acidity. Hard water is really just...

65 gallon? What kind of tree are you growing?

That's not too bad. Indoors much over 86 isn't typically desirable; some strains are more heat-resistant than others. As long as you're around there you should be alright. Might want to raise the lighting though. Otherwise intermittent lighting shouldn't stress the plants and it is certainly...

How hot is it getting? Do you have any alternative ventilation (are you cooling the lights/reflector)? Use an intermittent schedule tomorrow. E.g. set your timer for the lights to go on for an hour every couple hours, or whatever can be tolerated. Note that I don't think this is good for the...

I've always germinated seeds directly in potting mix. Most recently I had 1 out of 14 seeds not germinate and they were verging on a few years old. They still came up in about 3-4 days. Fresh seeds just sow directly into whatever media you plan to grow in. The depth of the media should be at...

Many underestimate the importance of water... of course it doesn't help that so many (particularly less experienced) growers are afraid of over-watering. Roots take up nutrients along with water, so if soil moisture is low nutrient uptake will also be stunted even if it isn't dry enough for the...

Let's put it this way: it's not the best looking seedling I've seen. It looks like it came up with the shell still on. This can happen if seeds are planted too shallow, sometimes it just happens though. Good news is I see what appear to be true leaves there. That considered it still has a good...

In general you can definitely use either HPS or Halide for an entire grow. If I'm running multiple fixtures I use both types. If I was to have to choose one or the other for a whole grow I would probably go for the MH. While halide bulbs appear to produce less lumens/watt, more of the light they...

Yeah it's just that where I am from ventilation has to be reconfigured based on the season, unless you have a sophisticated HVAC system. And forget about growing very much indoors in the Summer time, unless you want to run your lights at night and be up at 1 am each day tending plants.

I use rain water virtually exclusively, I grow in soil/living potting mix though. What I can tell you is there are actually other considerations in the process of collecting the water itself, especially if you want the purest/best quality rain water you can get. Were you going to get a...

Sorta looks like a male from the photos but for a definitive answer I'd need to see for myself. Otherwise try to zoom in on just that pre-flower, use the macro function if available and try to get the clearest picture you can. Checking it out with a magnifying glass might help also. You're...

Looking good. Sorry though I must say I kinda hate the expression "dialed in" as pertains to growing. Where I am from nothing is ever truly "dialed in". Seasons change growing conditions even indoors. Then of course different strains are going to want to be dialed differently.

I'd only be concerned if it looks like it is spreading/moving up the plant. How long have they been in their current containers and how big are they (the plants)? Also, how is your watering is it sufficient? If the pots get too dry the plants may show what appears to be a nutrient deficiency. If...

AFAIK it is much more common to find dolomitic limestone, which has something between 6-12% magnesium. Relatively pure dolomite lime would be roughly 50% magnesium carbonate (more likely around 45%), which would contain about 14% magnesium. Calcium hydroxide is easier to over apply and doesn't...
