400w HPS Orange Cookies

That's a ph test drop kit.

But if you want, and I don't know why I haven't, once you've got the vial , you can buy a bottle of universal indicator , 500ml for like $5 - $10 , that will last your lifetime..

More light, more heat, you increase extraction and/or use an air cooled hood.

However, you've got your thermometer in direct light, so it's probably a few degrees lower than it says. You should shade it with a bit of card so the IR doesn't hit it.

But a 4x4 needs a minimum of a 600w hps and its still on the weak side.
Or about 500w of good led, preferably 600w.

You'll see the difference in the last month.

The kit will last ages, when the little bottle is empty, buy a litre of universal indicator, which will last you 50 years.

It's cheap and reliable, unlike many ph meters.

Some of the branches are pushing thru the second net alreqdy I i didnt say this before in the last post the day after switching it to 12 12 i stopped feeding with dyna grow - Grow Nuits for veg and went over to Dyma Grow - Mag-Pro after we hit about half way ill switch to Dyna Grow Bloom
