The general rule for the pump is 1 watt per gallon of water. With the size of your reservoir you should be good with just about any pump. You may want to look into something a little more appropriate for growing like a durable tote as a reservoir, too.

That light would get you some growth. Does the seedling have a root structure developed yet? How big is your reservoir? How big is your pump? You may need a bigger stone, lots of bubbles are key! If there isn't a root zone dipping into the aerated water/nutrient solution and a 1"-2" gap between...

The general rule of thumb for air pumps in DWC set ups is 1 watt/gallon of water you're using. That pump will probably be more than enough for either the 5 gal bucket or the cloner. You'll be needing more light in there by the time flowering is induced. You may want to pick up a couple 42 watt...

Thanks for the input! I picked up a couple more air stones today. 2 Top Fin brand 6" Fine Bubblers. I'm pretty excited to see how they compare to those I already have. I'll post some pics once everything's set up!

With the 3.5" net pots in, I can fill my reservoir with 4 gallons of water/nutes and maintain a 1" gap between the solution and the pots. Will my air pump suffice? I've got 2x12" air stones hooked up now and after running for a few minutes the majority of the underside of the cover is covered...

Thanks, MBG! I had heard tell of the Lucas Formula, but didn't quite understand it at firstbongsmilie;) After a bit more research it doesn't seem too complicated. Just have to get my first grow out of the way first, haha! One last question if you don't mind:) I have my set up pretty much...

Thanks! Great condensed bit of info:D +Rep for you, sixstring!!!:bigjoint:

I just read something that suggested using 1/3 strength of whatever the bottle recommends throughout the entire grow and with your input I'll probably do that for my first run through! So if I'm starting from seed I just run the system with water only for the first little while then start...

I had another question that I just remembered. Am I still able to add molasses to the mix during the last few weeks of flowering to help "juice up" my buds?

Hi. I'm relatively new to growing, but have developed an interest in DWC and I think that'll be how I grow my next crop. I know that a lot of people suggest using extra diluted nutrient mixes when you start dosing plants in soil (ex - 1/4 strength for a week, 1/2 strength, full and so on . . . )...

So dose the plants with a combination of water/nutes/molasses then water only next time then the combo etc? I have heard that plain water isn't really necessary as the molasses isn't adding a bunch of gunk to the plant if used moderately, anyway. I just picked up the General Hydroponics 3-part...

Here's an article. Apparently the quality of the bud will be better because blue spectrum bulbs like MH emit more UVB light than red-spectrum HPS. I thought it had something to do with the type of high like harvesting based on the colour of the trichomes, guess I was a little off. Wonder how...

Hello again, RIU. I found some Schultz brand "Bloom Builder" (5-30-5) liquid fertilizer to use alongside my molasses during flowering and had a quick question. First of all, I was planning on watering with nutes (1/4 dose at first) then watering with molasses 2 days later (1 tbsp/gal) then using...

It wouldn't hurt. As long as you're running the right light schedule your plants will flower. Keep in mind that the light spectrum will determine what type of buds you harvest. Generally, red light will give you denser buds, blue will give you fluffier ones, though I hear plants flowered under...

Purple hues in the leaves could be the result of cool nighttime temps. Do you know what your grow room temps are? Highs/lows? Now, I have minimal growing experience - I'm currently flowering my 1st plant under 8 23w CFLs - but I've heard that may be one cause for purple leaf edges. I've also...

I'm running 1 "cool" (6500˚K) bulb for every 3 "warm" (2700˚K) ones. My girl seems to be enjoying it:D It also seems to be a popular configuration on these forums. I'd say that you should be fine as long as you've got the majority of your light in the spectrum that would most benefit...

Cool. I just found a great article here. It gives the Nutrition Facts of what I'm assuming they consider to be ideal. The amount of Potassium, Iron and Magnesium is considerably lower in what I've got going on, haha! I'm going to look around town for an alternative before using what I've got. I...

I should add - 1 topped plant about 6" tall w/8 23 watt CFLs in soil. I water every 48-72 hours depending on how the plant looks/feels when lifted and temps. I plan on using 1 tbsp/gal for weeks 4 and 5, bumping it up to 1.5 tbsp/gal for weeks 6 and 7 and finally 2/gal for weeks 8 and 9. May...

Morning, all! I know most people who add molasses to their water during the last few weeks of flowering use "unsulphered" "blackstrap" types, but I could find neither word on the carton I purchased. The ingredients are solely "Fancy Molasses (100% Sugarcane Juice)." It seems to have a good...

Looks good! You'll notice the inter-node growth start to catch up on lower branches. I even had to die down the uppermost pair of "tops" to keep the canopy even. Best of luck in the coming weeks!!!
