250w HPS Club And Help Guide

i got a 3x3x7 ft grow tent a 250w HPS should be good for 4 plants right? im just concerned about the heat thts why im not going with the 400w the tent has no vent holes ill have to make some and im not sure how good i can get the ventilation without risking light leaks ya know? vegging under 125w CFL and a few 26watters next week should start flowering once i recv my light but i have a adjustable ballast so a 400w wud be no problem to get? but i shud get by with a 250w right?

I'm also curious about you 250w HPS users in tents..what size tents you in? I was also looking at a 3x3x5-1/4 or something like that..if I used a 250w or 400w in there, would heat be a big issue? Also you guys with carbon filters, you got them inside the tent scrubbing or outside the tent with the air being exhausted out into it?

You can get by with a 250 with what you want to do. Duct tape will be one of your best friends lol, or that foil tape. The height is a little high, if you can work with the 400 go for it. You have I wanna say that Galaxy ballast or wth it's called, can't remember for the life of me sometimes lol.

Also welcome Ito.

airpot ppl,how hard is it to transplant out of those?im hearing up to 30% increase in yeilds with just switching to airpots. this thread just wont stop!its great to see everyone that is in here.

I'm also liking all of the activity here.. we might want to re-post the signature post

I took a look at the air pots, pretty reasonably priced for something that can be used many times. Although I'm liking the Smart pots I might have to give them a try, the Smart Pots are reusable but from looking at the air pots I can see that re-using them would be much easier.

good idea^likes.

Yeah the plan is to do that eventually, it's not in use yet so its not urgent but I was just gonna use duct tape or put a lid on it. that'd probably do it
Eventually I'll have the medium and nutes ready for use, going to talk to my mate tomorrow see if he's willing to chip in for an oz or so XD



Nah Ebb and flow and flood and drain are the same thing I think you'll find, you can have top feed ebb and flow but this isn't one of those, the principle is the pump fills the tray for 15 mins 3 times a day to water them, the roots should technically stretch to the tray, but yeah the plan is to root clones in those propagation cubes and then put in 3 or 4" cubes (pots aren't very wide), once roots are seen at the bottoms of the larger cubes I'll stick them in the airpots with the hydroton stuff, should have enough roots to reach the tray's

anyway enough rambling XD



those airpots are awesome! the root mass you get from them is immense and plants are ridiculously healthy. The ONLY bad point about them imo is that when you water it comes all out the sides and is r8 messy XD lol



I'm well excited too, can't wait to get it running!!

Damn I haven't had that many replies to a post in aaaaaages!

Stay Frosty guys!

Well i hope it works out for you dude ill be subbed up if you start a journal..

250w would be great in your 3x3x5 tent, you could do a 400w but you'll need some damn good extraction.

As per Carbon filters I have my fan blowing into it so it's on the outside, this is the most efficient way to use them in terms of smell dispersal as more of the filters surface area is used... A lot of people have them on the inside and have the fans suck through them as it is more stealthy to have it on the inside, however if you have a tent it's not exactly stealth in the 1st place, so I'd mount on the outside. XD

Airpots are SO easy to transplant out of, 1 way is to plant the smaller airpot directly into a large one, roots are no longer air pruned in the small pot and grow through then get air pruned in the second one... another way, they have 2 plastic screw in type things that you use when you put them together (they come flat packed and just require being rolled round and screwed together) just unscrew them and unwrap the root mass, transplant as usual.

probably because it's spring everyone's happy and wants to grow more (spring is good in the UK lol seeing as it rains most of our summer) XD

Haven't seen smart pots in detail but air pots you just unwrap clean down put back together and fill don't think it gets that much easier
