Hey everyone this is my second grow and ive decided I would use the scrog method in soil. I'm using Fox farm Nutrients and dirt. I have a 250w mh/hps switchable ballast The box its in is Depth- 2.5 ft, Width- 2.5 ft, height- 4ft. As well I have a 4 inch exhaust fan pulling hot air out and a fan blowing cool air in. Here's what the current setup looks like.

All of the plants are clones. The two smaller clones are Supergirl and the other is Great white shark.

Supergirl is one of the new powerful strong kinds! This plant is dark green, sturdy and easy to grow. Supergirl produces big swollen buds with shining THC crystals. After your labor of love growing Supergirl you’ll be rewarded with of her high THC content for hours in Nirvana. Flowering Time - 60 days roughly

Great white shark is a cross between a Super Skunk and a White Widow. Flowering Time: For indoors a suggested time of 8 weeks. Achievements: 2nd - Place - BIO-Award 1997, 2nd - Place - Cannabis Cup 1997

If anyone has anything to say or advice i could use please post away, Ill be updating as much as possible. :joint::joint::joint: Thank you in advance ..

I will def b watching this grow. I want to see how the great white turns out in hydro.Is ur great white from greenhouse? i have 10 great whites in soil going right now they r a fun plant to grow with outstanding buds . I found out that pumping them for right around 10 or 11 weeks was the best results. Just a couple tips. Check my grow out>>https://www.rollitup.org/grow-journals/348487-ganjas-1st-grow-kinda-2300watt.html and if u have any questions about the great white or any strain or aspect for that matter, dont hesitate to ask. Good luck with the grow.

Well i bought a glass sheet for my reflector and its working very good. I also moved the light closer to the plants and they seem to be doing great. The great whites touching the screen and the Two girls are just starting to fill out for there size. As well i went out and purchased a whole list of products i could use for hydroponics ( air pump w. stones, water pump and drip feed system, Aeroponic system could also be used as well, Cloning gel and rock wool cubes, ppm Meter,and pH up and down.) I still need to buy a ph meter and sum nutrients before i start. any advice??

UPDATE , 091410184215.jpg091410184309.jpg091410184224.jpg091410184741.jpg091410184431.jpg I only transplanted two because i didnt have enough dirt for the other super girl. The great white is in the green 5. gal bucket and its already growing into the screen. all of the plants are coming along great but the one super girl is a little root bound as its trying to grow. Ill get more piks asap

how many CFM is your 4" fan? Your dimensions are close to what I plan to build. I too will use 250 mh/hps. Concerned about the heat - 85 is somewhat hot - no?. What is your ambient temps? That is, the temp outside the box?
I will be growing with 61 ambient temp - so hoping the 250W will work. Jus not sure what size fan I will need to get the box to 78-80 or so.

Thanks so much for any advise. I've been searching for a while to find someone with the same specs!

The reason its 85 degrees is because i have a little fan pointed at the tops while the lights are on. Also the hood im using holds heat very well if i put my hand one inch under the glass i dont feel any heat at all. the inline fan im using is from home depot i payed 25 bucks for it and its got two different power wires you can hard wire. One wires for free air at 65 cfm or a booster which runs at 80 cfm. Im only using the 65 cfm and its working great. if you would like colder temps. i would suggest buying two in-line fans and making one as a intake and the other an exhaust.

Haha! My bad Rachshow. I was under the impression they were only here to harass which I see far too frequently here. I can also agree the negative rep would only be abused. Either way, I'm excited to see Supergirl when she flowers.
