Closet Grow gotFondue

This will be my first real grow, with a real grow light haha!

I started growing about 3 weeks ago with a 70 watt HPS security light I had purchased from Home Depot (HD). This was a completely failed attempt at growing. I returned the light and then went out and purchased a 400 watt HPS grow light and ballast plus air cooled hood.

I am in the process of looking for a 400 watt MH conversion bulb for this set up as to help my clones veg for a while. Any suggestions on conversion bulbs would be greatly appreciated.

Well my setup for growing:

Size: 6'x3'x10' (Will not be using all the space only 4 plants.)

Light: 400 watt HPS

Plants: Not sure yet, going to pick them up in a few minutes from the clinic. I am only going to get 4.

Soil: I am using Miracle Grow

Pots: two 12 inch pots and two 6 inch pots.

Nutes: I have SUPERThrive and some Marine Cuisine (some old lady gave me the Marine Cuisine at the local nursery)

Well this is the start I will have pictures posted when I get everything set up. The light should get here sometime today.

Conversion Bulb: htgsupply.com
Fans: Find a way to exhaust the air from the closet/area. That website has good inline fans to look at. I'm sure you can find better deals on other websites though if you look around for them.

small a/c in window or more fans

easy gotfondue just read your post and looking at your picture it looks like you need to sort out air to be inputted and extracted from that room.

QUESTION: can you cut holes in that door or not? if not can you get another door you can chop hols in?

The reason being you need adiquate air exchange. this is very important for the plant to grow propperly. i have found this out the hard way with a 400w hps light, i had majour problems with temp to which reduced my yeilds alot. i have since gone down 2 a 250w hps and will use the 400w for the last few weeks to fatten up the buds some more, but back to the point in question.
your size of light needs a cool tube or some kind of cool hood/shade and an inline extraction fan, just for the light to keep that coo.l it is possible to make them if you follow this link you should find a good one

or have a search around for the info, then you need at least 2x 4" bathroom extraction fans, one at the top of the door and one at the bottom, this should not not cost to much and make a considerable difference to your plants and yeild, i would also leave window open all the time as long as you cover the bottom intake fan with a filter like a stocking say it will keep little mites gettin in should be sweet.

i have also used same DIY co2 bottle which seems to be working well.

hope this is some use to you but keep up good work....

peace........

Forget about conversion bulbs mate. Get a dual spectrum hps, use it from start to finish. About the temps, a cool tube is def the way to go.

Hey MrFloaty! Thanks for that post man!

I had never even thought about buying a new door for that room. It has a double door set up. So I can have one door on the inside and one on the outside. I will probably just buy a new door and remove the old one and add those fans. I should have thought about that a while ago! Sheesh! Also the cool tube was something I was thinking about but never found any good info I will definitely make one of those if not buy one. HAHA! You saw that Co2 bottle? I was thinking if anyone could even tell what it was. You think that's enough or should I add like 3 of them in there?


Geozander, I have never heard of that! It sounds like an amazing thing to have I will surely look into buying one of those. Thanks for giving me that tid bit of info!


So the temps today in my area were 100+ the temp in my grow room reached a top temperature of 90.3! I was shocked that having the A/C on 24/7 and those two floor fans on a low setting blowing the cool air into the closet was enough to keep them down today. I will get right on the door thing today making one shouldn't be that hard two holes in the top and bottom some hinges, a lock and a door knob should do the trick. This also means I can rig up a carbon filter for later use.

Another question I had, since my humidity is also pretty low, what I have been doing is filling up plastic 16oz cups with water and leaving them inside my grow room. This seems to help a lot adding 30% more humidity to the air. The only thing I was worried about was pests, should I have to worry about them at all? I also have a fan running in there at all times.

easy gotfondue, its a pleaser to be of help to someone, i can defo recommend a small bathroom extraction fan for top and bottom of your door then thnings should get easier with the temp.
talkin of which the big necrotic looking peaces on your plants look like heat burn i would move your light a few feet away from your plants, remember the plants are little and the light is powerful and hot, they say put your hand just above the top of the plant if your hand feels comfatable with the heat then sweeeeeet if not move your lights away, they will still get enought light to grow big and fat.

the little white spots i think is the dreaded spider mite ( little fuckers) have you had fresh air comming in from the outside without any filter to catch the particals, if not it could quite possible be spidermite. have a look very closely at the plant leaves (use a magnifing glass if needs be), branches and on the underside of the leaves, you will seen very tiny little specs of what looks like dirt MOVING!!!!!, THEN ITS COMFERMED!!!!.

first thing get pure neem oil, or any spacific spidermite spray. spray your plants as instructed and then again a week later, the other thing you can do now is to raise your humidity up to about 80% this will cause the little fuckers to pop, and to also reduce the temp as much as possible at night. they will soon scater or die keep this up till no further signes show,
remove significantly damaged leaves after spraying as these leaves are not doing there job properly. if they are very badly spotted then the infestation maybe bad and you need to remove plants, disingfect growroom and start again.
these little shits are the bain of many growers lives, they say you should never come from outside to inside your grow room as you will bring in insects pollen from other platns etc, so much so to where spacific clothes just for your grow.

to raize your humidity there are 3 ways, place water in bowl in your your grow room like you have already, spray your plants reg with water, or get a humidifer from your Hydro shop or get one from a baby store they are cheeper there, its a little water bowl with heater and timer which blows out steem so help with breathing eh should be no more then £30. about $50

Cheers mate. Def trim those burnt leaves, they aint serving no purpose now.

Alright so, just out of curiosity I wanted to check my roots to see where they were at. I bought them at my local clinic so I didn't know the exact DOB. Well tell me if you think it is time to transplant them. I think so they are three different plants, not the same.

Wow, I didn't think they were this old.

I am going to go get some new soil right now be back in 20 min.


So I transplanted them into bigger pots. I need to go get two more larger size pots to match the other two.

Potted with ROOTS organic soil. I am now adding nitrogen to the yellow plant as I think that is the problem. The pH was good, and the water was also good.

So I just bought some SPRAY SAFE from my local hydro shop. He said it is one of the best that not only kills the mites but kills the eggs. Just pour it into a spray bottle and let at it. So covered everything with the stuff the underside of the leaves, the stems, the tops, the soil (just a little over spray but shouldn't hurt right?) I also trimmed the dead leaves off of that other plant (the one with the mites) and everything should be doing good. The temps are really reduced so far.

Working on getting the door setup finished and getting a cool tube made really soon! Should I start my plants on any nutes?
