Got an Auto that is 6 days old (from removing the seed off the cotyledons) it is roughly 1 1/2 inch tall and only has the first set of actual leaves developed , with maybe the next set just starting to show. It seems pretty slow and i'm not sure but maybe it's a little too cold? Temps are in...

Anybody tried the Philips LED's? They are 14w at 6500k and put out 1400lm per bulb , and just screw into the e27 fixtures, comparing this to the equivilent CFL which is 24w and 1450lm. The temp is alot lower with the LED . How far off the young plants should you have the LED? Still a good...

Hey ,i have a couple of Hans Panels and jnust wondered if i could also use some cfl for the lower half of the plant as a substitute light? The Hans Panels seem ok but when the plants get a bit bushy you start running into problems. Would cfl's effect the LED effective light footprint overhead?

Is there any disadvantage in growing under full spectrum as opposed to a veg light and a flowering light? I assume thre must be otherwise it just seems like you are making it harder for yourself , dealing with swapping lights. Are yields lower?

Anybody recommend me a light that will yeild well for one plant and also be cost effective with low heat? suitable for a small commercially brought grow tent.

Hey , I was attemting my first DWC and it all went well until the flowering stage where basically nothing has happened for a month. No new growth but still looking healthy on top , and white roots on the bottom. Ive been thinking why it's not flowering when the setup is the best ive ever done...

So i tried my first attempt at DWC . All in all I found it Lot easier then soil grow , no deficiency at all , the plant looks really nice and healthy. Tree truck stem on it as thick as my middle finger , roots nice and white with weekly res changes and daily ph checks and adjusting. I topped it...

This is an 8L container , 2 gal. Is that too small for a plant to veg and flower in? It would be good for a smaller size grow yeah? These containers seem good as they are insulated for cold things to stay cold all day and totally light proof.

I have just lowered my res by an inch . I have two airstone in a bucket with about 12L or so of water in it , the water level is 13 cm from the top of the bucket and about 10cm from the bottom of the netcup. I know you are supposed to have the netcup close to the water but my medium is actually...

So just wondering , to pollenate a cannabis plant do you need pollen from cannabis or just pollen floating around in the air in general? Any sort of pollen from any sort of plant / tree.

Say I want to make up a grow box and plan to line the back and side with mylar that wont get direct sunlight unlike the front of a plant. Will this be worse for the plant or better? I plan on having non see through greenhouse type plastic on the front. ventilation shouldnt be a problem.

To build a veg box , would car sun shield reflectors be a good alternative to using mylar from a grow tent or is it the same material anyway? I just figure it'll be easier to cut square and neat over cutting apart a grow tent.

I know I have had pollinated plants , shit happens. What happens now? Will the bud thatr has already developed deterioate and will it all just turn into a seedy mess or will it continue to bud up until the end of the grow like normal? Do seeds start developing once a plant has been pollinated?

Would a plant have a better yield if you had it veg for a month or so under lights and then when switching to flower put it outside to get natural sunlight? Would the end result result in better bud or will it most likely just send it into hermi mode?

As the topic says , is it that important? With the rates needed so low would you just be better off using good old plain water?

Confused if I should have pulled it off or not. It's the only one and it looks like it has the white hairs coming out of the bottom nearest to the stem. Inside it was just green bits which I'm not sure were more of the immature hairs? NFI.....

I assumed it's a female as it was flowering but I noticed this today. They look like sacks. Is that normal?

Beside that it will be smaller ,are there any main problems to have plants veg and flower in 5L / 1.5gal pots?

Do little young plants sometimes just grow looking very abnormal and continue till they die? Some i've seen look so deformed if it were a human baby it would be one without 3/4 of limbs. I also assume crappy growing plants will deliver a terrible yeild too right?
