We picked up a trs600 at a great price for our closed loop, and it was a night and day difference from doing it passively. Killing it on the little 73g column. However, yields were terrible on two runs with a 200g column. We were told the pump might not be big enough for that column. I'm finding...

quick question for the electrically inclined... i have a really nice mogul base with a standard plug that i've been using a 200 watt CFL in. can i cut the plug and wire in a HPS plug? thanks all...

so. i took a couple cuttings from a cool C99 pheno while it was flowering. they're well over a foot tall now, and continue to flower as they grow, despite grow nutes and 20/4 veg lighting. i have two of them, so i topped one to see if the new growth would be veg. it's been several weeks and it's...

here's the rundown... biggest fan leaves started yellowing first. now smaller leaves are beginning to yellow. i'm 3-4 weeks into flowering. several strains, all in 4" grodan cubes. top watering till runoff once every 24 hours using dyna grow. same nute combo i've been using with success...

so here's the short version: i have a wos landrace afghani that sat under my 400w veg bulb for two months. in that time, i cut it back repeatedly to keep the size down some. now it's been in flower for 33 days and the pistils are turning orange and the trichs are starting to turn as well...

i'm using sunshine4, (haven't grown in dirt for over a year), and have found something interesting. i've adjusted water in from 6.5 to 8.2, and the runoff is nearly the same regardless, 5.9-6.1. i was a total newb when i grew dirt last time and didn't measure runoff. what's the best course of...

i have a couple of mogul sockets whose plugs are for an hps ballast. can i cut them off and wire them to a regular 120v plug? i would like to use them for some big cfl's. thanks!

i've been top watering grodan cubes in my veg tent since there are plants in various stages of growth before moving them to the hydro flower tent. i would really like to be able to mix a large quantity of nutes at a time, but within a few days they begin to go bad. i've read a little about...

i have no idea why this is happening, but i've lost several plants now as a result. the trunk of the plant withers up right where it comes out of the growing medium and shortly after the plant, which is now being robbed of nutrients, dies. this never happened to me in dirt, but is an ongoing...

been growing under a 600hps for about a year now, but a buddy of mine wanted me to grow him a super lemon haze. sooo, i put it in my small tent with my old 200w CFL. hydro, with dyna grow nutes, which i think i've got pretty dialed in. anyway, i topped it thinking i could keep the size down a...

there is about 1/16 of an inch of standing water in the bottom of my flood tray. roots are long enough now that they're just sitting in it. will that be a problem? i don't think there is a feasible way to get the water out, but i can get the the pots up out of it if i need to. thanks!

so, this is my first hydro grow. built a little 4 gallon, 2 plant system. it's been up and running a week and a half. i can't seem to get the water to stabilize. every day the ph creeps up. started at 5.7 on day one. day two it was 6.1. lowered it to 5.7. day 3 up to 5.9. lowered it...

i'm pretty sure my plants have been nitrogen deficient, based on all the pics i've seen and posts i've read. however, i think there may be something else going on as well. fan leaves have been pale in color, and the ones that haven't come around get brown spots, like this...

i decided to make the transition from dirt to hydro, and am trying to get a couple of seedlings going to put in my mini hydro hands on learning system. problem is, i keep killing the damned things. i get em sprouted fine in my humidity dome. once they're popped up and ready, (by dirt...

can't seem to find a flood tray that's 2X3. 3X3 isn't going to leave me enough room to work in my tent, and 2X2 would waste space. anyone know if there are 2X3 trays to be had? checked ebay and google. nuthin...

i'd like to put together a mini ebb and flow system to play and learn with before going full out. my question is, is there a formula for determining what size resevoir would be needed for a specific flood tray size?

this is the third i've grown, and i've not had a bit of trouble until now. haven't changed anything either. i did just battle some fungus gnats, but the other plants in the tent are all fine... i've looked at several of the plant problems posts but can't put a finger on what's going on with it...

ive been growing in soil for over a year now and am kicking around giving hydro a go. i've read a good amount now, and understand less root space is needed per plant when growing hydro. correct? i'm planning on building my own system, but have looked at complete systems to get some ideas. my...

according to the legislature, dispensaries can buy up to 30% of their product from outside growers. the applications i've looked at distiguish between caregivers and dispensaries, but as far as i can tell there isn't a catagory for growers supplying only dispensaries. anyone know how this will...

i don't post much, but this board has been an incredible source of information. figured it was time i gave a little back. all of these were grown at the same time, with the same lighting and nutes. one 250w cfl per two plants with 42w cfl side lighting and the fox farm trio as per their feeding...
