I have 2 400 watt HPS lights in my 4x4 tent with a 250 CFM fan and i'm ok with temp. it never goes over 80F, even a foot away form the lights. i'm just afraid a 600 watt MH might be too much for a 2x4 tent :/ i just really want a 600 watter cause if i ever expand i can still use it. also i...

If i had a fan running constantly to keep the temp down, would a 600 watt MH be too much for a 2x4 tent? I want to keep my mothers and veg under a 600 watt MH in a 2x4 tent before i transfer to my flowering tent and i'm afraid it might just be too much light for that space

i did 18/6 for about a month (they grow really fast) and then i transferred them into a DWC bucket under 12/12 and like 2 weeks after i saw about 10 of the flowers turn into little tiny tomatoes. now there's about 20 of them and they're all still green but in a week or two they should be good...

nice grow man! i love DWC. It's so easy to maintain and it does wonders! I'll be checking in to see your progress. I'm currently not growing anything but once I do, I'm gonna have my mother sit in a DWC bucket (exactly like yours), veg using a drip irrigation, and flower with a 3x3 ebb and flow...

Most know how to increase yield, but what techniques do you use to increase the potency of your product?

These things cost a fortune so I thought I'd built one myself. Of course you can just use two tables but I enjoy thinking about these things, planning them out and then building lol. This took me just under and hour to built and about 35$ worth of stuff I bought from Home Depot. This is for a...

that would depend on how long you run the dripper for. assuming you know how much you water your plants everyday, get a digital timer/dripper/tubing(you'll need 1/2 and 1/4 inch)/water pump and hook it all up. set up the timer to 5 minutes and measure the amount of water you get. if it's too...

yeh i've seen it done all the time at my hydro supply store. it works

nice! i'm gonna have a similar set up. i have 2 400 watt HPS and my grow area is a 4x4 grow tent. how many CFM's is that fan?! i think I might've made a mistake by buying a 250 CFM :/ we'll see how well it performs. nor do I have a cooling system like yours. nice set up man! i'll definitely be...

i use a pump bag (you can get it at a hydro supply store) you put your submersible pump in it, but the whole thing in your res and it acts as a filter. it works great. it keeps dust particles (from the hydro ton) and roots out of your pump.

i have my thermometer hanging at the top of the tent and the temp this morning was around 80 with the door open and the fan blowing in cool air. and no for the moment i haveno exhaust but i should be getting my fan soon

your plant doesnt cover an area of 9 feet does it? i believe you need around 7500 lumens per square foot

ps, 1984 is great

hey man, i've asked ventilation questions about 10 times in here and it's very hard getting a response. i have a grow tent, it's the same size as yours. right now i only have a 400 watt HPS and what i do is i keep the door slightly open and use an oscillating fan to blow in cool air. this seems...

i know eh? try craigslist.com for complete kits instead of hydro/home garden websites (they're way too overpriced - i learned it the hard way) i bought 2 400 watt HPS ballasts + 2 bulbs + 2 reflectors for 110 CA$ lol but definitely agree on the grow tent. i'm gonna try to find a 3x4 (if they...

well thanks for the help. i'll be looking online to see if i can get a good deal on a can filter... any suggestions? also, will some of the fan's efficiency get lost if i pull it through a filter?

well i cant afford a filter + a fan strong enough to pull through the filter and keep the room temp down so i just bought a 250 CFM fan and hopefully it'll do its job of keeping temp and humidity down. i'll worry about the filter later lol so how many plants can i safely grow in a 4x4 area? i'm...

what kind of hydro system you got?

that looks like a sick plant! but yeh, that's what i'm doing right now until my exhaust fan comes in the mail (hopefully next week) btw, how many plants can i safely grow in there without causing too much canopy blocking the light for lower leaves. i'm guessing around 9 should be good? thanks...

i have always wondered why people don't do this. all i ever hear is sugar + yeast. it works but is it worth the trouble? i bought baking soda and vinegar a while ago and thought of doing exactly what you suggested. i also thought of using my ph down solution for this. i figure it's more...
