the optimal temp for veg is anywhere from 80-86F. growth starts to slow once it passes the 90F mark. At night, instead of using a heater, can't you use your 400w hps to heat the room up? Unless there are light leaks and may create suspicion. In terms of humidity, for veg I like to keep it high...

bump. please help?

Hello everybody. Well this is a 2 week old white widow plant from seed under around 50w of cfl. I have a 400w hps with a mh conversion bulb ready and am not sure if it is time to switch to it yet based on efficiency. Also, I plan to transplant this into a 12" pot and lst it. Is this babe old...

looking at the big picture, I think you'll be better off buying an actual grow light (mh/hps) at that price. For $200, you can easily get a good deal at HTG or someplace like that. I know I got a 400w hps with a mh conversion bulb for about 200. I'd say the only benefit from the cfl light is...

HTGSupply is always a reliable source for some pretty cheap lights compared to the other hydro stores. The shipping could get a little expensive though, but I definitely think it's well worth it.

a simple test i do is put my hand right above the tops of my plants. If it's too hot for my hand, it's way too hot for the plant. having a fan blow the hot air from the light away from the plant can help you maximize efficiency by letting the light hang a lot closer to your plants, thus more...

there are a few in this area. My favorite is BetterGrow Hydro and the other that I've been to is Atwater Hydroponics. They both are small shops but have large selections of everything you possibly need for hydroponics. (BGH has a great online store as well which you can check what they have in...

well i personally don't like the smell/taste of vinegar and sure don't want my buds tasting like it :P. But in all seriousness, the local garden center was having this clearance sale and sold the lime (raise ph) and sulfur (lower ph) as a pack. 5lb box of each for $2.99. so nobody knows if...

of all the knowledgeable experts and experienced growers here, nobody knows? :(

trainwreck is a good choice, very forgiving and resistant to molds/bugs and pretty easy to clone. As crazyoutlaw said, flowering right after they root will maximize your harvest because it's better to have a bunch of small plants yielding say about a 1/2 o each than 1 fully grown plant that...

With indoor growing, you have much more control as to the time you want to put into each stage. It all depends on your light cycles. I usually veg for about 4-5 weeks, then switch the light cycle to 12/12 (with the dark period) to make the plant start to flower. There is no required amount of...

I am going to start a indoor soil grow soon and came across E.B. Stone's Soil Sulfur at the local garden center. They come in pellets and dissolve in water. But the question that I had about this was if I use this to lower the pH of the water/soil, will there be an excess of sulfur in the...

what's even better than a double double animal style is animal style fries :D. McDonalds is always a good alternative especially with their 2 bigmacs for $3.50 deal now

from my experience, jiffy peat pots are not the best way to go because they retain too much water and can contain some creepy-crawly stuff inside (bugs and sometimes even mushrooms). I personally like rockwool because it offers the perfect water/oxygen ratio for the roots and as long as there...
