What's a good starting point for H2O2 per gallon in my res? My temps hover around 71-73. Wish I could get it lower but even after insulating it that's as low as it will go.

This is my first time running flood and drain and im basically learning on the fly. So far everything is good but i was wondering if I needed to run my air pump 24/7 or can I cycle it. Im running a 18 watt 760 GPH pump into two 6" diffusers. 15 gallon res. Right now it runs all the time. Temps...

Im setting up my first flood and drain grow (mainly grew in soil or peat) and have decided on using 6" rockwool cubes. My question is should I fill the area in the tray between the cubes with hydroton? Ive read to use a coco mat as well. Or do i need not worry about it?

Does anybody own one? Im wanting to try hydro out and want a flood and drain set up i think. Im height limited so this interests me since its only 10" tall...

So I've been SCROGing for a few years and decided I'm sick of dealing with it. Don't get me wrong it's done me well but it's just too hard to maintain in my little room. It's hard to reach the back of the plant to trim under growth, hard to check for problems and if I have to do a filter or fan...

Ive been using Hydroponic Research's Veg & Bloom since my first grow but the cost is getting out of control. Dont get me wrong its a good product and ive had some really good results but i want to find a way to get the cost down. I use Veg & Bloom Dirty (for peat) $120 for 5lbs , Life additive...

i have never had a single problem with seedlings all the way up to flower. Usually my problems happen late in flower so this is new to me. Haven't wavered on my setup in the last 6 grows. Growing in promix hp with lots of perilite. Only feeding 100ppm of veg&bloom. Ph'd at 6.5. The leaves are...

Ive only made oil a few times using ISO but recently caught hell from a friend for using it so thought I'd try everclear. Used an ounce of Alien OG bud in one and CBD OG trim in the other. Both trays were crystal clear (trim has green tint) but after a while the one on the hot plate (very low...

does this look like a plant 9 weeks in flower or a ph problem? Checked my meter it's on the money. Feeding at 950ppm plus some flower nutes at 100ppm and calmag in soiless medium. Ph at 6.5. I've had this issue before but it was a bad meter so my meter was reading low. I want to try and get...

Here is one aspect of growing that's always troubled me. How much to trim. I grow scrog so obviously everything under the screen is removed. I've already snipped a lot of the fan leaves but this damn thing seems to compensate for everything I trim! It's Cali connection CBD OG. I know I should go...

if you have a problem with storage solutions drying out and getting crystallized try this. Plastic wrap a small jar and poke your meter thru it.

I've been using hydroponics research's veg&bloom for several years now in my soiless grows with good results but am considering switching. Been looking at Canna products and General organics. Anybody have experience with either in peat based mixes?

Starting another plant while I wait for my Alien OG to finish up.

Here is a question ive been asking for some time and havent really gotten a straight answer. Ive been growing soiless from day one using Promix HP and shit tons of perilite. Ive mostly done trial and error and have had good results with one strain (pennywise) but have had issues with others...

Popped a new strain a few weeks ago. Same plan as all my other grows; soiless promix hp, hydroponic research veg&bloom nutes, 5 gallon smart pot but this time I might be growing under LED if I get my light done before I transfer it from the clone cabinet to the grow room. I get good numbers from...

Ive been growing in a 3x3 space with a 4.5' height. I run a 400w mh for veg and a 600w HPS for flower in a cooltube and fan. The issues im having are slightly high temps in flower (high 80s) and the cooling tubes being in the way. Electric bills arent that high but could always be cheaper. Im...

I think I developed a magnesium deficiency. The last few grows have done this late in flower. I already use calmag and pk booster that has mg in it. I started foiliar feeding an Epsom salt solution and gave it a shot of calmag this morning to help the problem. In starting on week 7 of flower so...

Is this a nitrogen deficiency or a PH issue? Leaves are starting to turn yellow. Growing in soiless using promix. Hydroponics Research all in one nutes and HR pk booster for flower. Feeding at 500ppm at 6.0ph. Ive got 6 grows under my belt with this set up and havent had any issues at all but i...

Just starting this grow after I had to scrap my GAS newjack because of a hermi issue. Like with all my grows...using ProMix HP with lots of perilite, Hydroponic Research nutes, 400 MH veg, 600 HPS flower, scrog and i start them under compact flos. So far it popped quick and broke through the...

So I was in menards the other day and spotted a little Pyrex dish for $6. Instantly knew what I needed it for. Found a piece of lexan for $4. It's thin but works. They wanted $60 for a piece of 1/4" and wasn't paying that. I think I have a chunk at work I'll aquire. I already have a pump and...
