So I've decided on T5HOs..

but which are better? or as long as they're 54 watts? I've seen 80 watt bulbs but I think those would just be overdoing it. but then again more light more bud right? should I follow the 100 watts per first plant and 50 for every additional rule?

I was thinking about getting a 4x8 tent and using 4x4 for flower and 4x4 for veg now I wanna do T5s for veg and I have a 1000 hps for flower. I just don't know how many T5s or size I would need for that footprint. I wanna do 7 plants in 7 gallon pots.. or 3-4 plant in 10 gallons. I wanna scrog though veg with t5 and flower with hps.

anyone with direction or some advice from experience chime in. I know nothing about indoors. and I'm just getting started.

thanks.
 
I have a 6 bulb t5 array thats 48" long in 5x3 space. Seems to work just fine...

7 plants in 7 gal pots might be a lot crowded in a 4x4 space. I used to run 4 plants in 5gal pots in a 5x5 space with 1000w which worked well...
 
My first advice is to get yourself two separate tents or sacrafice the turn around time and veg and flower and the same tent.

HTG makes a tent called a short stack($100) that will allow you to veg plants to about 20" in 1 gallon pots with t5's, i'd recommend their tek 4 light($130) in that tent. An 8" duct fan should be enough to keep the tent cool and will only run you another $35

after you veg your 7 plants in that tent, transplant them and then move them to the 4x8. Throw up your trellis and veg them another 6-8" before inducing flower. That tent does amazingly well with 3-4 600w lights in flower. You need a minimum of two 600's IMO because of the 8' length. Also I'd suggest an 8" HV Fan for exhaust and to reduce down if you go for 6" flanged reflectors.

get this tent for veg:

With this light:

With this fan: (needs flange too)

Then flower with 3 600w lights in that 4x8, with an 8" HV fan for exaust.

No i need to question anything just buy and set it up...

I wouldn't be able to do 2 foot plants cause of the stretch after the flip. I plan to scrog but doubt that even after the 2 week flip and train they'll still be really close to any lights I use? maybe the t5 wouldn't do so much harm being that close?


EDIT: WAIT NEVER MIND. LOL
 
Thats a lot of plants and larger pots for the space. I would do 4 plants in 7g pots and scrog with a 600w or 1000w hps and do 2 ft plants. I have done 3 grows from start to finush with just t5ho and i was pretty haooy with the results.

54w is T5HO. 95w is T5VHO.

If you're going to have HPS, why not MH in veg? What will the T5 do for you? (Or, why not do CMH for veg and flower. I haven't used it. But, it seems to use less energy, produces less heat, more useable light.). If I didn't live in a hot climate I would use it.

If money isn't an issue, buy Area51 LED.

my 2nd comment was a lazy re-post after thinking my first comment didn't go through.

I would highly suggest doing something similar to what I suggested. you should be able to turn out a crop every 10 weeks +/-
with the benefit of a separate veg room that will only require a little over 200w and a cheap fan to cool.

If you were to opt for a MH(HID lighting) in veg your going to need a larger veg space and a more powerful fan. Being that you plan on trellis netting anyway, you are more than likely topping early in veg and keeping the plants shorter to begin with.....So why bother with a light that requires more height and more energy to cool?

BTW this all assuming your in a traditional soil or soilless mix.
 
I just got a 4tube 4' t5, I usually run 600w veg MH, thinking of using it during fresh transplanted clones and seedling for my veg, for a week or so, then hitting it with the 600w. Just to try and save a little power bill $.
 
Also i wonder when you really break it down comparing CMH to Cree Cob the CMH has a better spectrum >>>>??? i own Nanno;s and presently 4 - 1215 WATTERS contemplating implementing three nano 315's inbetween the 1215 Cost wise i think this will infact be the COB destroyer

Why Don't you run sog and forget about vegging? Work on your cloning game. stagger the clones, maybe 15 every 3 weeks. If you cram them into a 4x4 tray, 49 ONE gallons fit.

If only growing them in those 1 gallon pots, would you put them in flour immediately, or let them veg a little as soon as they come out of the dome?

Do you get results comparable to a 450 watt HID, and how much penetration can you get out of those t fives?

Don't know. Never run it. Never weighed, its personal use. Three plants with eight main buds about 15 inch long and big around as a 16 oz water bottle.

I'm going to weigh this run. Hoping for a pound.
 
I'd need it to be able to withstand a strong super soil. Starting it straight out the dome is possible too. Probably won't be as root bound at the end but will require a lighter mix and more attention, sooner . I personally would party cup them then transplant into the 1 gal's full of super soil.
 
I have a 354w (54wx6 bulb) t5ho along side an older mag ballast 400w mh in my veg area. My observations..T5's produce a shorter thicker plant, but at a reduced growth rate. I see noticeable differences in stem thickness on the T5 plants, but they are generally about 2 weeks behind the 400w in height. Only thing i can think of is i can drop that T5 right on top of the plants where the 400 is 12" away and much hotter. Heat is my biggest issue, just like others..the T5's help to keep it under control a little better. My T8,T5 and 400W each have a dedicated 2x4ft area under them, big enough for me to run a 34 site clone tub.

I've found they don't like going from flouro's directly under high intensity lights, a transition stage seems to help. I run a staged setup mothers/clones under a over driven t8 light@ appx 250W, veg under a t5@ appx 350W for about 2 weeks, move under a 400W mh to transition to HID's then they go into the flower room under the 600w with mh's for another week then i switch out to hps bulbs and flower. Just lifting your HID up high at first will do the same thing, just lower it slowly over a day or two.

Here's what to do..go with 2 4x4 tents. Set them up so you can just swap out lights. Run the T5 at first, about 2 weeks before you flip for flower, take clones,once your clones are rooted move them and the T5 to the next tent and get your flowering lights in the first tent. If you plan on scrogging you aren't going to want to move plants once they start getting big.

appreciate all the tips.. and I didn't even think about the light stress from the transition. good point. how many plants per T5 8 bulb? or would two 4 bulbs be even better?

I wanna do a 4 plant scrog. 2 pounds sound possible in a 4 plant scrog in a 4x4 tent?



I own a 1000 watt hps, and I intend on getting maybe another 600. but like you stated heat is also going to be my biggest issue. what's hotter, 2 6s or 1 1k? which covers the canopy better for a higher gpw?

I don't see how there could be much of a difference between a single 8 bulb or (2) 4 bulbs, other than you could spread out the (2) 4 bulbs for slightly more sq ft coverage..it would be negligible IMO. Either setup will only cover an appx 2' x 4' area..you could do a SOG with 32 small clones - 1 clone per 6" sq - or you could grow a few big plants. I can fit 6 in 5 gal buckets under my light, comfortably, probably 9 if i wanted to push the outer edges of my light spread

IDK what it takes to get 2lbs in a 4x4..or if it's even possible. Most people are happy to get 1 lb in that sized area.

2 600's will have more heat but it won't be as concentrated, unless maybe you were running a dual bulb hood. I run 2 600's in cooltubes because i don't have the height to get 1K's up high enough from the canopy. I don't see 2 600's fitting in a 4x4..the 1K will probably be better, just going to need a good fan to cool it.
