My indoor garden room is finally done. I was only planning to grow veggies this year as a trial run before possibly doing some cannabis next winter, but watching the plants grow has me itching to start a good medical strain right now. It's been quite a few years since my last grow, so I want a...

This is my first post in several years. Just getting back into the indoor gardening scene, and I’m already going to piss off a bunch of people on this forum. I got excited about new technologies since my last grow, but I fear it’s all just another marketing stunt. Here it is. Can we all just...

For those who are vegging with Eye Hortilux Blue MH bulbs, I would like to know where you buy them and how much they cost. Retail for the 1000W is around $240, but I have seen them as cheap as $115. Problem is that the last two I bought on Amazon were advertised as new but I received used bulbs...

Just wanted to see if anyone might be interested in some very high-end LED grow lights. I might be able to get a hold of some lightly used ones at a decent price. All of them are Lumigrow Pro 650 models, and they were used for about two years in a University greenhouse. Not a scratch on them...

I'm sure this subject has already been covered, but my searches didn't answer my exact question. $100 is too much to pay for a bulb that only costs $5 to manufacture, so I'm trying to locate a vendor with reasonable prices. 1000Bulbs.com has decenet pricing on a few select bulbs, but...

I started a thread a few months ago about an idea to build a curing system, and I finally completed the project. The heavily modified microfridge should automatically maintain ideal temperature and humidity levels throughout the curing process without environmental adjustment guesswork or need...

Knowing that I am nearly ready for harvest, I've been checking the trichomes daily. Yesterday, all samples viewed under the microscope had almost entirely milky trichomes but not a single amber one. There seems to be some disagreement on what percentage of trichomes should be amber before...

I recently built a curing system for my last grow and found that the final quality of my herb dramatically improved. The buds are denser with just the right amount of moisture. The first build was a prototype, and I'm now working on building the real deal. Basically, it will be a semi-sealed...

I've just encountered my first male flowers, and I'm not sure how to interpret the unfortunate results. All four plants in this grow were cones taken from plants originally grown from unknown seed. The original plants were all female with no signs of male flowers, but one of the clones did...

Now at the end of my best grow ever, my mature buds are suddenly sprouting new growth. I checked the old trichomes under a microscope over the weekend, and I have about 70% cloudy, 30% clear, and just a few ambers. I was preparing to harvest this weekend, but now I'm not sure what to do. I...

My current grow is maturing much faster than my last grow with the same strain (GSC), and I'm having trouble gauging when to start finishing nutrients and flushing. I'm only 6 weeks into flower, and the girls look they might be ready in two to three weeks. My first question is, can you guess...

I know this subject has been brought up several times before, but I'm hoping to get a lot of feedback from experienced growers who have settled on a specific bulb distance that they consider safe for their plants. I'm still trying to decide whether to use the 600W or 1000W HPS. Assuming that...

I decided to go organic with all future grows, and I like the reviews I've been reading about Earth Juice products. Conveniently, the local hardware store has the basic stuff for very reasonable prices. However, Bloom, Grow, and Catalyst solutions don't contain much potassium, calcium...

I started testing my soil pH today, but I can't seem to find a good explanation of how to calculate the soil pH based on initial tap water and runoff. Is there some formula for calculating it? Tap water was 7.76, and runoff was 6.76.

I'm going to change up my lighting scheme with this new batch, and I wanted to get everyone's input. Last grow, I flowered four plants in a 4x4 area with a 1000W HPS and two T5-HO fixtures (4-bulb, 4-foot = 20k lumens/each) for side lighting. The plants did well, but I noticed that the buds...

I'm trying an experiment with my girls. Just wondering if anyone has ever tried harvesting the top half of the plants and then harvested the rest at a later date. I recently harvested four Girl Scout Cookies plants and found that that there were still tons of smaller immature buds under the...

I'm trying to decide if I should harvest this weekend or next weekend. I've been watching the trichomes, and I understand that you want mostly cloudy ones. Clear is too early, and amber is too late. But what happens if you have about 60% cloudy, 39% clear, and just a few amber ones? Here are...

My girls are in their 7th week of flowering and have suddenly become more sensitive to the HPS light. They stopped stretching weeks ago, so the bulb distance hasn't changed, but the leaves that are directly beneath the bulb have started yellowing while everything else looks great. The closest...

I grew this variety from bag seed, so I have no idea about its genetics. However, I recently stumbled across a pic of a Chemdawg plant and it looked very similar. I also discovered that the source of the seed claims that Chemdawg is one of his favorite varieties, so there's at least a chance...

It seems to me, I read somewhere on this forum that you cannot put an HID and fluorescent fixture on the same circuit because it will damage one of the ballasts. Since I'm currently designing the electronic controls for my flowering room, I wanted to see if this is really true or just an urban...
