By eldenvron ,29 Apr 2013I have seen videos of scroggs where they use the vegetable trellis netting, this is what I thought I would try. My only issue is the spacing you mention in between pots. I have all of my pots centered under […]Read More

By Jared ,29 Apr 2016Hey Laura , a variety of factors could be slowing your growth. So u know your soil ph? Nutrients? Light n wattage? Grow room temps n humidity? Jus asking so I can help :)
-
By Jared ,29 Apr 2016I was gonna say if I had to bet. It's a lighting n temp/humidity problem. And prolly very little nutrients..
-
By Kelley two feathers ,24 May 2016Try heat pads under your pots cold roots are not Happy
-
By Jay ,03 Sep 2016Your problem is your lighting. Not enough lumens. You need a high pressure sodium or metal halide. Or full spectrum led.
-
By Kdu ,29 Dec 2016CFLs work fine if they are powerful enough and you keep them close enough to the plant.
-
By sean ,03 Feb 2017Use several Clfs if your you have to ,get 40-42w 2700k soft white six will be sufficient for one plant at least 150w total. Several smaller 40-42w are better then one 250w bulb the more the better you really can't […]Read More
-
By Jay ,18 Nov 2016How many lights are you using? How many total lumens? What light spectrum? What grow medium? Slow growth is usually caused by not enough light. But if you rule that out it could be a fresh air or nutrient deficiency.
-
By Brandon Schroll ,06 Apr 2017How close to plant is light?. What watt is light? With fluorescents unless they are touching the plant, they're pretty useless.
-
By latewood.ILGM ,12 Apr 2017Brandon Schroll, How close light is to plants depends on what type of lighting system you choose. HID lamps are placed anywhere between 18" - 36" depending on size. LEd lamps can be placed a bit closer but, also need […]Read More

By Joe ,27 Jun 2018you need to feed your plants more frequently. Food and Water and Light = growth... also I suggest using a mycorrhizae 2x a week after you plant until you go to flower. "Great White Mycorrhizae" is the best.
-
By John ,20 Jul 2018Your seeds are too old. That's just not a thing. The problem is that you are using fluorescent lighting which is one of the worst sources of plant lighting. If you were to use a high pressure sodium light, or […]Read More
-
By John ,20 Jul 2018That should have said "your seeds are NOT too old.
-
By Domingo ,05 Sep 2018You need to upgrade your lights
-
By Dex ,09 Sep 2018I dont think its the seeds as much as the lighting that is affecting the speed of your growth. While effective in germination and seedling stages, t5 and cfl lighting systems just dont create enough light penetration to be able […]Read More
-
By Down South Hustlin ,02 Sep 2020Fluorescent bulbs. That's your problem.....Fluoro's need to be like no more than 6" away from plant. You would do better investing in LED lighting
-
By 1600p ,04 May 2013Laura, it could be anything. However, I'd say based on your description, you may have a lighting issue. Get better lighting. And check your nutes.

-
By latewood_ILGM ,18 Jul 2018John Murphy, You can do a SCROG with 1 plant or 4 plants or even 6 plants in your space. Either way will do you good. Keep it simple and enjoy your 1st effort. See you in the forum. Perhaps […]Read More

By David ,31 Oct 2013Amazing information! I've learned a lot and look forward to applying this knowledge. One question I have is about the stage where the plant starts growing through the screen, and your clipping it down with a tie to make it […]Read More
-
By mountainmike ,04 Mar 2016Did your questions ever get answered about repeating the process of tying the branches down? It is a little unclear to me. Do you have multiple attachment points to the screen on each horizontal branch, or just repeat with all […]Read More
-
By Jay ,18 Nov 2016Yes you want to keep the main branches at the screen level. Whether from tucking over and under the net or from tieing it somehow. Then each branch will develop flowering shoots all along the length of it. These shoots […]Read More

By Jay ,18 Nov 2016If your worried about people seeing it then it's probably not a good spot to grow it. Even if legal in some states...still have to worry about theft/vandalism. Could easily google for strains with low odor but pretty sure all […]Read More

By latewood.ILGM ,09 Mar 2016James. Most people start there plant and leg it fill out to 6-12" and then build screen to correspond to the height of the plant, at that stage. Experienced growers can get away with setting up a screen before hand […]Read More

By latewood.ILGMl ,10 Aug 2016Diana, I would not recommend Tomato cages. You would be better off with some welded wire, or horse fencing. :)

By sean ,30 Jan 2017Mine is only "10 above my plant due to the fact I'm doing a stealth grow, smaller space requires shorter screen height, make it so you can move it a little bit. Higher space go higher. Also ilgm compact seeds […]Read More
-
By latewood.ILGM ,18 Nov 2016Shepses, It really depends on your personal grow method. Some growers keep their screen about a foot above the top of the pots, and other, grow the plant up to the screen 2 feet above the pots. Either way will […]Read More

-
By latewood_ILGM ,11 Jul 2017onathan DaCostaSilva, Logic would dictate that you would take advantage of the longer photo period in order to fill the screen prior to inducing the flower photo period. Once the screen is filed you flower, allowing the plant to stretch, […]Read More

By Chynel ,13 Sep 2018Would you recommend scrogging and/or topping of plants grown outdoors (California) and if so,when?
-
By latewood_ILGM ,25 Sep 2018Chynel, SCROG is a technique developed for growers with limited grow space in order to take full advantage of light and space indoors. Outdoors you have full Sun all day around the plant and SCROG is not necessary.
-
By Old guy ,30 Sep 2018Just a note on scrogging. First attempt. Took cuts from 8 month old monster mom at 2 weeks in flower. Will they still give me a main cola or be predispositioned to multiples ?
-
By latewood_ILGM ,04 Oct 2018Old guy, You will still get a main kola or 2, depending on whether or not you top the clone. It will not grow like a seedling. Happy growing :)
-
By Old Guy. ,09 Nov 2018Thanks for help. Spot on. They are deffinately not growing like a seedling. Is a sweet amnesia by G-13 labs. Never seen such prolific branching. Still another 3-4 weeks before 12/12. Have high hopes. Pun intended.

By Don ,19 Apr 2019You say that you start your flowering just before they start to pop through the screen is this because the flowering growth will be enough to continue the trellising process for the remainder off the completed grow cycle
