do you think i can pull .35 grams per watt with this grow?

what yield range do you think i can pull?

Hello RIU friends!

i have two plants (i believe they are Green Crack) that i found in a bag of buds. I originally started with 7 and had to downsize to 4 due to space concerns and 2 ended up being males, so yea..... but thats behind me and Ive moved on and I'm focusing all my attention to my 2 girls.

i vegged them in a small 2x2 cab under 500 watts of cfls, while my flower chamber was under construction, they flowered their first week in the same chamber and i was finally able to move them up to the bigger 6X6X6 flowering room with a 400watt HPS setup. i own a 600Watt bulb i want to use but I'm in the process of fixing some ventilation issues in the room when i use the bigger bulb.

The tallest one is 36" tall, followed by the other one standing at a 26" tall....... the bigger one has always been the tallest and bushiest of all the plants i planted, it was also the one that pre flowered first.

they are about to start their 3rd week of flowering and I'm starting to see some nice buds forming all over them.

the temperature has always been a steady 76-80F day 70-73 at night in the room, they are potted in FFOF soil in 2 gallon pots.

i have fed them a fertilizer mix recommended to me by my local hydro store guys, and i recently switched to Floratech's Recipe for success kit because i got ahold of 23 free kits!!!! lol don't ask how. the plants seem to be liking Floratech's nutes.

my air cooled reflector allows my plants to stay about an inch form the glass or about 2-3 from the bulb no problem. the walls are painted flat white and i have some styrofoam squares coated with mylar to reflect light where there is no walls.

i try to make the most use of the light so the plants are cornered in an area that is about 4X4 and i use the mylar squares to make a little reflective chamber.

i know that there's probably no way ill get 1 gram per watt.....

but do you guys think i could be able to pull off .35 - .50 grams per watt? if not how much?

help me out guys, i won't cry if u guys wanna provide some constructive criticism... I'm just tryina get some point of view from your past experiences.

is there any other techniques or stuff i could do to the plants to help me increase my yield? lollipoping? pruning? supplemental light? plant steroids?

thank you so much in advance guys!!! :leaf:

pruning the lower growth that doesnt get light helps, and you can never have to many lumens so go for the supplemental lighting too, throw that 500 watts of cfl around the plant, also low stress training is helpful, there are soooo many techniques you can use, but in the end its all about personal preference and space management, but they are looking good, is it just me or are they stretching a bit? but if your keeping the light 3 in away i have no idea why they would be stretching
 
Scrogging and better ventilation. I'm gonna guess your temps are on the high side.

Pull the hot air out of the hood as well. You're pushing through is highly inefficient and ineffective.
 
.35 per watt comes out too 6.25 ozs between those too.which is a large yield if you ask me with the 500 watt cfls,but 600 watt hps will definitely help you maximize for sure you could even compliment the hps system with cfls, some may disagree but ive talked to people who have, could depend on the strain and what not. good luck to ya

thanks! I'm going to see if i can put up some cfls for the bottoms of the plants...

isn't it too late for LST tho?

i did think they were stretching a little lately... but i think is just natural elongation????

my temps are always between 77-79F so i think thats pretty good?

good point about the fan tho, I'm trying to buy a little inline fan, i did read that fans can pull 4 times more air than pushing it. thanks for your reply!

they are not under the 500 cfl lights they are under a 400 HPS, hoping to mount the 600 within the next week or so...

why would people disagree with cfl light supplements?
 
You could snap the tops to get the canopy lower down where teheran rest of the bulk of the plant is. In their current size and height with no changes I'd say you could expect around an oz per plant.

really? just 1oz per plant? thats only .14 grams per watt with my 400Watt HPS?!!!!
 
in my opinion its really never too late for lst espically unless your growing autoflowers? any auto should not really ever be lst just because its constantly in flowering its just about the plant not recovering enough during flowering to focus energy on those buds.. and to be honest i have no idea why anyone would disagree? something about too many lumens and different spectrums on diff parts of plants... bs if u ask me, if your using those to compliment under the 600 as well. i expect youll have a great yield

thank you very much bro for your honest answer :) :weed:

I'm not basing it off your light so much as the current size of the plants and how far in flower you are. You could put them under a 1000 right now and I still think you'll be around the 1 oz per plant range. Of course a 1k would penetrate all the way down and you'd probably get more like 2 but ur rocking the 400.
 
I say that because you have very little side branching and the colas are quite stretched with not so many nodes to build bud there.
 
2 gal pots .i pull in 3.5 _4 oz with my 1000 watt. .in 3 1/2 gal pots. which i now veg in,i moved to 5 gal bucket and doubled every plant .i say u pull2-31/2from 2 gal pots
 
Not even,just because the stretch and low short branching,i have 2 2ft 12/12 from seed plants flowering with over 10 colas each that will yield more than your plants because i used 400w MH for 3 weeks and i tied them down then 400w hps,i get less stretch and more actual foliage growth.
 
who sir i veg 400 mh two my 1000 pentrate better than 400watt hps ,got one ,when i first bought equip,ent. didnt take ,two grows before upgrading ..i grow vert,no lst or chit maybe fim few tops here and there .since upgrade to 1000 i never look back

I was referring to the original post and since you use MH and HPS you should notice the difference in vegging with each.MH = short bushy HPS = Stretchy.I vegged with hps on a few plants on my current grow and the rest started with hps,the ones started with hps are almost as tall as the ones in flower but lack branches.

can i use a MH bulb on an HPS electronic ballast??
