Growing Jack Herrer (Jock Horror) in a coco mix. My first grow. I think I have some time to go since my trichnones are still either clear or milky (mostly clear) and none are amber yet. I may have overreacted with my calculated harvest time. I don't want to harvest too early.I stopped all...

I've been battling mites off and on and am about a week from harvest and they are back! I need some input as to what to do so close to harvest. I don't want to use predators (such as lady bugs) since they wouldn't be here in time and my wife would flip out. I need to know what to do to avoid...

Totally bummed. As you can see by the pollen sacs, my first two plants are males. The best I could hope here for is a hermie but it doesn't look that way either. These were my "flagship" plants. I have 4 more that I will be putting into flower in a week and am hoping for better luck. Does...

Yes, a forum dedicated to coco or soilless growing. Maybe a subforum of the hydroponic forum.

I am growing in a 50/50 Coir/Peat Moss mix with a touch of perlite for good measure. Fox Farm nutes ph'd at 5.8 (after the nutes were added) but my runoff is measuring 5.1 on one plant and 5.5 on the other (it was a water to almost 30% waste versus volume). Should I be concerned? Is it also...

I have a RO and have been using RO water but I also have a well that has a high iron content. Can I use this or will the high iron damage my plants?

I'm using this at 1/2 peat moss and 1/2 coir (this stuff) and some perlite. The manufacturer is at X-Seed :: Garden Soil :: X-Pand Instant Garden Soil Has anyone used this stuff? I'm concerned because it has nutes in it (so I consider in not virgin coir). I can get it locally so this is...

I'm using coir with Fox Farm nutes (Big Bloom, Grow Big and Tiger Bloom). From reading, I guess I should be using different nutes for coco. Has anyone had a successful gro using these nutes? I have had some problems (See...

Going to try my first cloning soon. I am going to do them with Jiffy Peat Pellets. I plan to nuke the Jiffy pellets for about 10 minutes then put them in an oven at 250 degrees to kill and of those nasty fungus gnats I keep hearing about. I have a heat mat and propagation tray with humidity...

I had two really nice plants but they are both exhibiting possible overfeeding (one worse than the other). I am using a 50/50 mix of peat moss and coir and into that mixture, putting in about 20% of the MG perlite. I could only find Miracle Grow perlite (feeds plants for up to 3 months crap)...

I'm growing in both a DWC and soiless (50% each coir and peat moss)I ph'd my water to 5.8 but after I adding my Fox farm nutes (3 tsp of Grow Big), my ph dropped to 5.3. I always assummed you ph'd first and then added nutes. Should I again readjust my ph one more time to reach the optimum 5.8...

I am attempting to locate a S51 mogul socket for a 400 watt HPS system. In my searches I notice E39 sockets are 400 watt mogul sockets. Are these interchangable? The same thing? Also, what is a good online source to purchase the S51 socket (or the E39 if they are the same)?

First grow of Jock Horror. Everything was going fine until a few days ago when my biggest plant started exhibiting really light green leaves on the new blooms and burning on the edges of the fan leaves below them. Behind the plant in the picture is another plant from the same strain that does...

I'm doing a soil grow right now (first grow) but I'm playing with a basil plant in a very simple DWC to get my feet wet. :mrgreen: So far, so good, especially considering the cutting was half dead when I put it in the DWC (I had it in a vial of water rooting and kind of neglected it). I have a...

I have a basic carbon scrubber and cooltube ventilation set up now but was thinking of an improved system for my grow room. I basically would consist of a heavy duty scrubber mounted inside a soundproofed plywood box using either foam or acoustical tile. The scrubber and fan assembly would be...

I am building a cooltube and am concerned about the wire gauge to the tube (Don't want to start a fire). I know what I will be using should be ample. 12 AWG (12 gauge) rated for 600 volts. 3 conductors with rubberized waterproof sheathing (pricey stuff but want to be safe). Was just wondering...

If I were to remove a male plant and keep him in vegitative state, would this prevent the pollen sacs from maturing until I allowed him to go into 12/12 flowering? (I know only females "flower") If not, how about if I just kept cloning and destroying the "father" until I harvested and...

Newbie who has done his homework. Bought a boatload of Bake-A-Rounds for my 400 HPS (I have four of them, bought 6 tubes, I like backup) and bought one MH conversion bulb (400 watts of course) - ITS HUGE! No way it will fit in a Bake-A-Round tube. Are their any others DIY's to accommodate this...

First time grower in soil (going to keep it simple in the begining). I have a ph meter, ppm meter and soil ph tester. Plenty of light. Confused as all hell by all these nutes. Thinking about going with the Foxfarm Kit Grow Big / Big Bloom & Tiger Bloom. What else should I get (yeah, I know...

I know depending on the strain, lighting, nutes and environment, different plants can achieve different heights and that during flowering, plants can grow anywhere from 50% to 200% more than their vegetative state. Also read flowering can be forced at any time but that the earliest should be at...
